The New UPR Plug n Play™ Single Valve Catch Can System for all 2014 to Present 5.3L and 6.2L Equipped Silverado and Sierra Trucks.


By popular request we have decided to come out with a full UPR Plug n Play™ Single Valve Catch Can System. Offering the most advanced patented internal design with multiple stages and dual diffusers and coalescing filters. This is not just a billet catch can with an internal cylinder and a scraper skirt like all the other manufacturers offer. We incorporated our top of the line Patented Diffuser System that will deliver the best performance hands down and never have any capacity problems or need to be an oversized can. The new UPR Plug n Play™ Single Valve Catch Can is specifically designed to be run hot and deliver the BEST coalescing and condensing. This was done to force the moisture and condensation that collects in the catch can to evaporate instead of building up and overflowing your catch can and requiring it to be drained all the time and wasting time making messes.



This is how we are designing all of our new catch can systems to require much less maintenance and deliver even better performance. We have been continually improving our catch cans for years and we have improved our internal filters in all our diffusers in an effort to be sure we continue to lead the way in oil separators. We are very concerned with making sure you have the most reliable maintenance-free catch can system available. Nobody wants to have to keep checking the level in their catch can. 


The Kits all Feature Continental 300psi never collapse insta-grip braided hoses and not some cheap rubber fuel line or heater hose. Most importantly there are no clamps or cheap flimsy connections. We only use OEM Plug n Play™ direct replacement fittings to give you a system that will meet or exceed your every expectation. The very best part is everything is pre-fit and ready to go not just a roll of hose and a bunch of bagged fittings.


I have included the links to the UPR website and put the kits on special on the website so all you have to do is just purchase them directly without any hassle or headaches.


Normal retail is $249.99 and we have them on introductory pricing special of $199.99


The kits come complete with all the UPR Braided Lines and UPR plug and play™ fitting for a complete installation

of the Brand New UPR Plug n Play™ Single Valve Catch Can System with Check Valve.

Yes, UPR continually works to have the most efficient internal diffuser systems with all our catch cans. Making sure we always deliver the very Best Coalescing and Condensing Performance for your PCV system. We've even designed our coalescing filters to be custom exact fit to the Internal dimensions. We have also taken into account the wire thickness and weight of each stainless filter to adjust the airspeed and size of oil droplets that get sucked through the improve the coalescing characteristics.


Stuffing random wads of loose stainless steel wire or media is a sure-fire way to show the world how little thought went into a proper coalescing and tuning airspeed for maximum PCV function and crankcase evacuation. Most people have no idea just how important these variables are when it comes to a finished product that will give you the very best performance in hot and cold weather.


Our Catch Can Systems are designed to maintain the maximum airspeed so you can get the Best HP and MPG because they maintain the most vacuum through the PCV system. Other brands actually restrict airflow to help control oil which and they do not take into account that the loss of vacuum and airspeed will reduce overall ring seal and performance and by not allowing the crankcase to be properly evacuated.


Our small cans were developed to compete with the bigger 4" catch cans that outperform all the other small catch can systems.


This is not a flame or a knock against any other brand. We just have an extensive amount of time into testing and improving the characteristics of the PCV system to be able to deliver maximum oil control without reducing airspeed and or vacuum to the PCV system. There is so much more to a catch can and its true function than to just add a can and hoses and slow down airspeed and mount it in the coolest location to be able to offer the best performance.


I would appreciate keeping this a positive post to benefit forum members and enthusiasts and not turn this into a brand bashing post.


Thank you, Joe

i have a couple questions, I haven't looked into the full operation of the catch can . I was wanting to know what, where  and why are the check valves used/needed and curious as to if there could be a concern of seals gaskets blowing/leaking from pressure build up ?  I travel to upstate NY in the winter and the temps can be extremely cold. So I have a concern of condensation and freezing causing the CC to not operate correctly, and potentially cause ill effects such as blocked lines or frozen check valves that could cause a seal to blow or leak somewhere. I look forward to hearing from you joe and you are always willing to respond with good information. thanks

I was also about to order the Single Valve P&P but wanted to ask about the benefits of the dual valve and what the Pro check valve upgrade would really do.  From the little bit of reading I've been able to do, the dual valve setups seem to really benefit boosted or high pressure scenarios so I don't know that it would be that necessary on a 5.3L, correct?  Regarding the Pro Series check valves, I guess I'm wondering again if I'd see any benefit.  


Right now it looks like the Single Valve kits are on sale.  I think I missed the sale on the dual valve kits.

Cold Weather and UPR Catch Can Systems – ( UPR Cold Weather Catch Can Performance )


We mount our catch cans in the hottest location to reduce condensation and any chance of freezing in colder

climates as we have tons of customers in NY, Canada, and Alaska that run UPR Catch Can Systems. The most

important thing is just to empty right after every drive in the winter and keep any moisture out of the catch can.


Pretty simple procedure and we've never had any customers have any engine problems with seals or gaskets.

Unlike other catch can manufacturers we developed this catch can to perform the same in cold as it does in

extreme heat.


That’s the reason the USPTO awarded us a UTILITY patent for the multi-stage and multi-chamber diffuser system

by the unique condensing and coalescing it delivers. This was a very necessary improvement over the standard

barrel and scraper design other manufacturers use with just a single diffuser inside.


We have a Patented Series of Diffusers and Coalescing screens that outperform all other designs while maintaining

maximum airflow for optimum vacuum and eliminating any freezing issues. You will be fine, my daughter lives in

Saratoga and has a Dual Valve with Clean Side Catch Can on her SUV and it never misses a beat on her SUV.

I’m very familiar with the Cold as I'm originally from CT.




UPR Pro-Series Check Benefits with Dual or Single Valve - ( Great Upgrade to improve efficiency )


The Dual Valve is just beneficial to deliver more vacuum from Dual Sources and with the Pro-Series™ Check Valves,

you'll really benefit as they flow 4 times as much air any other check valve available from any catch can manufacturer.

The increased airflow is highly beneficial when you have any type of catch can system as the increased airflow will

result in a much stronger vacuum source and scavenging effect in the crankcase delivering better MPG and overall

ring seal.


This has a DIRECT relationship to the overall performance and longevity on every engine. Just like a vacuum pump

the more efficient it operates the better results it delivers every single day. Most important features with our kits are

we only use Braided Hoses and OEM Plug n Play fittings to eliminate the days of CHEAP rubber hoses that can crimp

or suck closed and UGLY hose clamps that can loosen and never give you a clean secure fit.


We can always be contacted for forum discount on the UPR Plug n Play Dual Valve Catch Can Kits.

Ok so the dual valve catch can in theory work better than the single valve,? So can you use a dual valve catch can without the ccs, what is the purpose of the ccs in a dual valve catch can or any single or dual valve catch can set up. What do the internal workings or material look like in your CCS. Do you have a picture of what the dual valve set up looks like on a 6.2 with out using the CCS.  Either with a Cai or stock intake. I'll be using a CAI.

      To my fellow Enthusiasts,
      For everyone to understand about catch cans and condensation. Certain companies promote catch cans with all the water or moisture they collect and that gives honest manufacturers a BAD RAP. I will share the fact that most of the condensation / moisture a catch can collects is from the catch can and not the engine. Engines heat up so fast they force the moisture to evaporate and thus do not contribute much to the condensation / moisture in the catch can that gives it that Starbucks look. The catch cans actually introduce more moisture and create a steam or cleaning effect on the engine internals.
      Thin wall and welded catch cans will generate a lot more condensation / moisture as the thicker walled sturdier construction catch cans will not suffer from the same extreme temperature sweeps. Thicker catch cans will hold temperature better while driving as the thinner units will cool quickly allowing them to continually produce condensation / moisture while driving and this will fill the can quicker requiring additional maintenance for no reason and create a lot of wasted time.
      The design is critical to how much oil will be separated before getting into the intake tract and combustion chamber. I have been watching many re-sellers make claims that create fear or post millions of DI pictures of engine failures and giant bottles of Starbucks looking fluids collected. The proper design of a catch can is to be able to keep the catch can hot enough to evaporate the condensation / moisture and still stop all the oil.
      Most catch can manufacturers run the coolest location possible to hide the lack of efficiency and this is why so many catch can manufacturers show all these pictures of the Starbuck's looking Mixture.
      The fuel that gets by the rings or gets collected in the catch can is harmless and can be burned in the combustion chamber without any negative effects.
      The biggest thing we see with all the late model engines is how much stronger the PCV system function is and how much more oil they introduce and scavenge through the PCV to be ingested into the intake tract and combustion chamber.
      Please keep in mind that a catch can is an oil separator. Larger catch cans collect 2x to 3x more condensation / moisture being mounted in cooler locations and that feeds the sales pitch and bad rap for catch cans that are mounted and function properly in hotter locations than others. I have worked hard watching many so called experts regurgitating things like send it to Blackstone and wait till you see how much they collect in the winter etc. LOL, these guys are selling something that has nothing to do with the normal PCV function. A PCV system mainly introduces oil and fuel into the intake tract and combustion chambers.
      Either way, this is just to inform the readers about the reality of a Catch Can / Oil Separator's function and I'm not here to get into a he said she said and would just like to state the facts. 50yrs of racing experience and engine building with the very best in the industry has allowed us to test and see these things and it was the reason we have been able to continually discover many variables about the PCV that many still haven't figured out. We're not just some aftermarket street car guys that sell products and never talk down to anyone or want them to be uneducated about our products or a products true function. We sell our Catch Cans based on the true value and function and deliver the very best hoses, fitting and components across the board.
      I'm not pushing any product here and just sharing the information about how critical the oil separation is and the rest of the things that get thrown in to try and sell and promote these products is nonsense.
      Thank you for taking the time to read this and feel free to PM any questions as I'm always happy to help you make the ( best-educated decisions )

      I have had the Elite Engineering E2 Catch Can on my 2014 Silverado for about 8100 miles and just performed my first oil change since it was installed. (Don't worry, I use Mobil 1 Annual Protection). Shocked is an understatement of my reaction when I discovered how much oil my truck is burning. After seeing how much was captured by the Catch Can, I am very glad I decided to install one. I have run a catch can in my Camaro for several years and it captured far less oil between changes so I was very surprised with how much was captured this time. After doing this first check - up on the catch can, I now plan to check the can much more frequently (every 2,000 miles or so) to see how much is being captured. I will be uploading some additional follow up reviews on the catch can and how it is performing. Overall, I am completely satisfied with my purchase and will be purchasing from Elite Engineering again. Note that this engine is shared among many GM platforms such as the Silverado, Sierra, Yukon, Suburban, Tahoe, Express, etc.
