When are people going to understand that CAI does not increase HP. I like where is says 25-50 HP gain but with a computer tune. Your motor is only going to pull so much air in. The only thing a CAI does is give you more noise under hard throttle and makes you think you have more HP but you dont. Your truck already has a CAI but have sound deading baffles to cut the noise down thats it and it does not restrict air flow. DONT BELIEVE EVERYTHING YOU READ AS THEY ARE TRYING TO SELL A PRODUCT.

 

Now if you have a motor that pumps out 600 HP then yes you need more air flow in but that is at high rpm

At least they were honest about needing a tune for full potential. Before I got my tune I dynoed my truck with a new cai and gained about 6hp from stock, not sure how much I gained from the bb tune with the cai but did get a nice jump in hp and tq.

OK, so let me ask here. I am not new to GM vehicles, but I keep reading where you guys say there is no gains to be had. Do you have conclusive proof of this?

 

I have a 2009 G8 GXP. Car came with the Vette LS3 rated at 415h/415t from the factory. On back to back dyno runs with a Rotofab intake kit I picked up 13rwhp before we even touched the tune on the vehicle. I went from 342rwhp when I came into the shop and left with almost 363rwhp after the tune was done on a 500 mile old vehicle. Since then once the motor broke in the car is now a little over 370rwhp.

 

That is fact, not fiction and not word of mouth from the maker of the CAI kit. The stock intake tract is designed for NVH (noise, vibration and harshness) in mind. They use baffles to to make the truck quite under load, not exactly the best thing when it comes to power. A engine is an air pump, more air into the motor and provided you can get the air out will make more power.

 

If CAI did not work I would suspect GM wouldnt be offering them as a after factory part you can get thru the dealer then now would they?

Yes they would, as they are in the market to take money from those who believe the hype just as anyone else is.

Once again hype that is not true. We have done back to back runs and each time we have always seen a gain with a good name brand CAI kit. Each and every time, gains that were still there months down the road. The easier and more efficeintly the engine can pull the air in the more power that can be made, there is also an effect called sonic super charging that happens when air is pulled into the engine and then hits the backside of the valve as it close, that airflow is reverberated and then pushed into the next open cylinder.

 

So once again, CAI will produce gains and you dont always need a tune, but you will make more power with a tune if you are ok with tuning the vehicle. I may even tune the 2001 Silverado here once I get some time.

There was also a noticable difference in my truck after my Airaid CAI install. I had my truck on the dyno at my race car engine builders after my CAI install, it showed a gain of 9hp (don't remember the torque but that also went up, would have to find the sheet) Going to have to have it done again after tune and exchaust.

Some people will swear until they are blue in the face that a CAI is usless. Doesn't matter if they are presented with evidence or not.

I can tell anyone who will listen to reason, that CAI kits DO make a difference. Even more of a difference when combined with a tune and exhaust. I have tested my Camaro on the Dyno and verified this and have seen similar results on many other vehicles. The CAI is not only about the volume of air, but how much easier it is to pull air into the engine without all those silly noise reduction baffles that GM is required to install.

 

My experience is with K&N kits and now with the Volant system. I am not selling anything and not trying to argue.....I just honestly believe they work.

      OCI, not when but why?

      By KARNUT · Posted

      It seems fine because it pulls everything out of a hot engine. I’m not going to worry about a thimble full with 5K oil changes with synthetic oil. Every other oil change is at Honda they pull the plug. I watch them through the process. It turns out going to Honda what amounts to their normal oil change intervals.

      I tried tapping it.  This might sound like a dumb question, you should feel vibration or some type of noise when it turns on? Can someone please verify? Thank you all!

      first oil change - 2026 2500HD gas

      By Chuck FB · Posted

      I feel better now for my own view point and actions or lack there of towards the dealership service theme reading your post and others. GM corporate is who offers the two free oil changes on the HD trucks and I bought my truck in Feb of 2025 and those oil change offers run out within 2 years I believe and I highly doubt I will be using either one of them. I had asked if I could officially give those free services to another customer ( a friend ) and they said no, its all a GM corporate thing based on the vehicle in question. What that service advisor did however was go into a little story about how such and such customer was denied engine warranty because he had done his own oil changes because then they are not documented ... you see where that goes and so an employee playing the game of scaring the customer into having the service work done there most certainly triggered my thought process. At a later date I did talk to the person who handles warranty claims at the dealership and she said to be sure to document the oil changes and keep receipts for the oil and filter ( coped the receipts from cases of Mobil oil and case of filters I bought from them ) and the vehicles VIN, the date of service, mileage etc and staple that together as a record I would give them if that was ever needed and I keep my own log book for services for each vehicle as well. Oh and about 8 months after I bought the truck the dealer starts calling me to offer a maintenance service since they haven't seen my vehicle show up on their system ... for the mere fee of 300.00 Canadian to change the oil and rotate the tires and a few other minor checks and I declined the offer, I get the call again a couple of months later for the same thing and she could tell I was not interested and she asked if they should take my name off the call list and I said yes, do that !.    By the way did you happen to keep your factory oil filter to open it up and see the surprises inside as I expect some will show up as per the odd little sliver of metal shaving and particles that the filter does trap along with bits of grey silicone sealer that come off of the inside edge of mating surfaces. I have cut open every filter so far on my truck although few miles but have changed the oil often and the second filter was vastly better with very little of anything, that first filter was the unsettling one as I expected it would be.

      I get why they do this…but man…not ideal. I only extract on inboard boat engines because the drains are buried and even then I hate it because it’s easy to leave a quart behind with that method.   They should market it as an “oil refresh” not oil change!

      I only get oil changed where I can watch. Valvoline pulls through the dipstick into a see thru glass. When done they show me the dipstick. About the only way they can mess up is using the wrong oil. But that secret wouldn’t stay secret long. Honda uses TQ wrenches on everything. You can watch through a plate glass window. Discount tires does that with tires. Trust but verify.
