After Market Air Filter

UPDATE: I drove the Blazer with the K&N Air Filter and there is a difference. Is it a huge difference? No. There is a noticeable difference during shifting. It runs smoother. It's not that much faster, but it rides much nicer.

Looks a bit less restrictive than the factory filter and should last longer. This is always good first swap to make on a new vehicle. I do wonder whether we will actually see aftermarket intakes for the 3.6l.

Do you have plans to direct air better to the intake? I have seen that done with other vehicles in the past and the result seems to be good.

I just can't speak for how it might impact what the O2 sensor was calibrated for

I don't think I'm going to go any further. I don't know much about engines and mods. Just the basics for now.

Hello everyone. I just had to ask.
1. After installing a K&N filter it shifts smoother?
2. After installing a K&N filter it rides smoother?
3. After installing K&N filter it is faster?
So GM is so bad at designing that their air filter screws up the shifting of the transmission, makes the ride worse, and slower. Maybe I should avoid chevy altogether....

no difference really. get more are, might bump the hp/trq up by 1 or 2. about it.
common misconception on air filters. it's a filter, it's not gonna make a lick of difference in tranny or suspension.
and faster, definitely not. an air filter does not make any vehicle faster. in fact no upgrade does. not a matter of going faster, but getting to target speed faster. doesn't mean the vehicle is faster. as it is, blazer is fast enough, stock she'll get up over 210kms/hr. (for the sake of rules, i am not admitting to having the blazer up that fast......)
