No issue at all warranty wise, GM even offers a CAI thru the performance parts catalog for the K2xx trucks. As long as you install it correctly then you will be fine. Most will say to not use a oiled filter like K&N, but I've never had a problem with them. My current setup is a dry filter Airaid system.

Nothing wrong with K&N. There are those who say K&N messed up their trucks or MAF however K&N has proven time and time again that when you install and oil the filter properly and don't have a heavily modified engine that will suck the filter into the intake of the engine, it ends up being a very very good investment. Great sound, with a note of performance increase. There will always be nay sayers, but K&N has one of if not the best Q/C and testing of their products and they stand behind them. They will back you up if the dealer gives you any grief over having one.

With a DI engine, intake valve coking is a potential problem. Using a K&N air filter adds a source of dirt and oil that will end up on intake valves. The OEM paper filters filter better, and will flow way more air than the engine will pull.

This is the wildest and most incorrect thing I have seen in awhile. There is not nearly enough oil in a K&N filter to "coat the valves" with oil and dirt, I mean unless you are rigging up some sort of automatic oiling device that continually sprays oil on the filter for some reason or are cleaning the filter daily and purposely over oiling it. I have been using K&N filters since 1990 and never had a issue ever with on in any regards to either killing a MAF or a transmission. I oiled them as per the instructions and they work just fine.

The correct term is "coke" not "coat". How many vehicles have you used a K&N air filter on have had DI?

 

Here are some photos at the same magnification, of K&N filter media, vs OEM paper filter media. This clearly shows why the K&N passes more dirt (and oil) than the OEM paper filter does:

Passing more media, eh? That's one of the oldest wives tales in the CAI book. Try again.

Actually it's not...good number of "dusted" turbo diesels out there to justify that statement. The dirt passed through a K&N filter caused scored cylinders. I know I had a K&N on a 99 Dodge Cummins and could wipe a dirty film out of the intake tube that was passed by that media, I promptly removed it from that truck.

 

I think K&N has changed their media since then though...

Keep in mind that K&N was originally meant for circle track racing, where high flow and some dirt ingestion was acceptable because the engine was rebuilt periodically...that didn't work so well when they moved into the daily driver market. Again, I am fairly sure they have since changed their media, but problems did exist.

Well from the test shared on this side, the AC Delco paper filter with just the Airaid M.I.T. tune flows better than a full K&N intake kit and others. I'm glad I went the Airaid M.I.T. route this time with my '14 instead of a full intake kit like I did on my '98.

 

As far as the oiled filters, I think as long as the filter isn't over oiled it shouldn't have any oil coming from the filter itself.

So now we are pouring a name brand soda on the intake valves, what good will that do. Do the DI engines need some caffeine to start their day right? Or did you mean "cook" the valves?

 

Even still, no issues at all. Not enough oil is going to come out of a properly oiled K&N filter to do a thing, my 2016 truck is my 3rd vehicle with DI and none of them had any issues at all with oiled filters on them.

From your comment, you don't have a clue what intake valve coking is. Educate yourself by reading this article on intake valve coking. Hopefully, you will be able to comprehend it:

The term is Coking, not coke. I am aware of it and once again still not an issue that will be changed or made worse from running a properly oiled K&N air filter.

When everything is said and done, there will always be haters for whatever reason. K&N has been in the CAI business longer than anyone else and stands behind their product, regardless of what application it is used for. I'm betting they have the best Q/C out there out of all the air filter manufacturers, and they know their stuff. If they didn't, they wouldn't stay in business in this day and age. The next time any of you are in Riverside, CA- I'd like to invite you to go take a tour of the facility and talk to them about any concerns/questions you have. These people know their stuff. Do they make the best application for your vehicle? That's up to you to educate yourself and decide. But I am very pleased with my experience with K&N products, and am damn proud to have a K&N drop in filter in my truck. If it didn't make any difference for me, I would have stuck with the regular factory/WIX filter, which no doubt is also a good product, and I have nothing bad to say about them.

      Silverado 4500-5500-6500 are they still being produced? Would have sold better as GMCs as well

      By C/K Man · Posted

      There was talk over the last couple of years that the contract to build these trucks between GM and International would not be renewed.  International moved production of all their other trucks besides the companion CV model out of the Springfield plant some time ago when they opened their San Antonio plant.  That left Springfield only building the Silverado Medium Duty, International CV Series, and some Express/Savanna long wheelbase cutaways.  International also put the plant up for sale some time ago.  This all answered my earlier question as to why GM and International did nothing with these trucks since they were introduced, as they had basically become a market 'placeholder' with a finite life.    The Silverado Medium Duty/International CV trucks were interesting combination of a GM powertrain, electrical system, and K2XX Silverado cab with an International chassis that was supposedly designed for a step-van type vehicle they never produced.  They were manufactured in International's Springfield plant along with the IH MV series initially.  When first introduced, there was much talk that the Silverado Medium Duty/CV would eventually get a gasoline engine option along with other upgrades and GM and IH would work on a class 6/7 joint venture truck.  This was before VW bought Navistar out, after that happened no more was said.  Draw your own conclusions...   About the time talk started that the GM/IH joint venture was not going to be renewed, rumors started that GM would develop a new line of medium duty trucks themselves.  The story is the new trucks will be part of the next generation HD's due in 2028, and will still feature a 'straight rail' chassis design that the current medium duty has.  GM views this as a desirable feature that differentiates their truck from the competition.  A gasoline engine option is also expected.  As the current Silverado Medium Duty remains in production until September 2026 and there is still a lot of inventory available do not expect any official word for some time.   I believe GM remains committed to their successful partnership with Isuzu, and all the LCF models will still be available from Chevy Commercial dealers.  Isuzu is on the cusp of opening a new large plant in South Carolina and there is also speculation that this may result in new product for both Isuzu and Chevy Commercial dealers.

      Software Update

      By nfisherman · Posted

      I have a 2026 2500 HD Ultimate. My phone app says there’s a software update available. It’s something about improved battery management and something to do with the running boards. I follow the instructions for the update but the “Check for Updates” option is greyed out in my settings menu. Has anyone else seen this? How did you resolve it? The help message just says “see your dealer” if the download doesn’t work. I’m just trying to save a trip.

      Exhaust Question

      By newdude · Posted

      Fuel mileage?  That's all how you use your right foot.  Exhaust will give you sound.   Stock exhaust 5.3 is 2.75" diameter piping.     If the truck is nice and worth putting some $$ into it, I'd go for a Corsa catback.  I had one on my 2019 old body 5.3 and it was just perfect.  Zero drone, just driving around and cruising on the highway you'd think it was stock, but when you opened it up it was like a Camaro with the factory dual mode.  Corsa bumps their catback to 3in diameter.
