Has anyone installed an aftermarket cold air intake system or even seen one to install?

give it about a year. Aftermarket companies working on it. Should be a no brainier. Modified version of the cold air intake of the Cadillac CTS 3.6L. Exact same motor, just without turbo.

I thought I saw an option for a cold air induction on the GM web site.
Chevy does have their own GM Performance Department. They might have something, but doubt they'd have it so soon for the blazers. Anything in their "SPORTS" lineup they would have for sure. Apparently their supercharger and turbo kits for the Camero's are pretty good. Worth looking into if you want to maintain any kind of warranty.

Obviously not a cold air intake, however, I replaced the stock paper filter with a K&N high flow oiled air filter. I order it directly from K&N's website.


I can't say it's a night and day difference in performance, but I've got to believe it flows air better than the stock filter.

I agree. Performance not so much, but I do get better mpg from the factory filter.

Sooooo, this last weekend I tried to build my own cold air intake and it was... interesting.

I have a Cold Air Inductions intake on my 2010 Camaro but since it is off the road for winter (Canada eh) and I had an older 2016 Sierra intake laying around I chose to mess around in the garage a bit.

GM uses the same MAF mount and intake tube for both the Camaro and Sierra (and many other GM vehicles) so I just cut the Sierra intake tube flush before the stock box, slapped on the 5 inch cone and slid it into the Blazer intake tube.

Bingo bango boom she worked no prob. legit right? fired her up and went for a burn. I wasn't expecting any performance increase although my butt dyno did notice a bit more low end and intake nose was considerably louder, which is what I really wanted!

2 min in... check engine light. F*&K, had a feeling this would happen so pulled out the code reader as I suspected MAF code. sure enough, P0101 - sensor has a Range/Performance problem. Slapped back on the stock intake, cycled the ignition, code gone.

I have a bit of technical know how with GM and LS engines so my guess is that the MAF was too close to the cone filter and wasn't getting constant air flow. the code appeared after warm up which makes sense since it was running in closed loop during warm up (ECM pulls from air fuel table instead of MAF for "warm up") without fully doing a data log and unlocking the ECM and using HP tuners i wouldnt be able to confirm.

anyways, long story short, I will just have to wait for an official intake to be made or if I get bored again I might try adding some tubing in between the filter and the MAF and test again.

I saw the K&N Cold Air Intake System for 299.99 on EBay.

The thing about getting it from them directly is they won’t ship it to California (where I live). They said it is not for use in CA 👎🏻
