I put an S and B cold air air intake on my 2024 Silverado 6.2 when it had about 1,000 miles on it and have always maintained it. I had been noticing that the truck seemed down on power and just wasn’t running right. I never thought it really did. I was thinking more about the s and b design with the air scoop just pulling hot air and all of the weird intake noises I got from it. The placement of the maf sensor by the pcv hose also made me question it. I have about 13,400 miles on the truck and today I was driving around and decided I was going to put the stock airbox back in it. I just thought that the s and b was not helping the truck. Right before I was going home to put the stock airbox in and got a check engine light for the first time and the truck really wasn’t running good. Pulled the s and b out and put the stock airbox in and all the codes for the maf sensor and map sensor went away. It was like driving a whole new truck. My fuel mileage went up to about 18mpg (was getting 9) and the power and smoothness of the truck was amazing. I realized that the truck already came with a cold air intake and that all aftermarket ones do is provide sound which makes you think they help when really all they do is cause problems and make the engine perform worse. One thing I did notice on the s and b was the pcv inlet tube was leaking a bit which could have contributed to some of the problem. I also think I got the s and b put in the truck before it was fully broke in so I thought it made more power but really didn’t since the truck was not even broke in yet. I was surprised because s and b was supposed to be a higher end air intake. The only performance air intake I would consider is the one made by GM. Sorry for the long thread, just thought I would put my experience in here to warn others about these so called aftermarket cold air intakes that do absolutely nothing for your truck but make sounds.
