Air Intake - Performance matters!

[Jergin01]

I am looking at many different air intake kits. I was wondering if anyone bought one that actually made a big difference on their blazer. I have a 4.3L engine. Please vote or tell me your opinions.

I ghettoed one together using the existing parts on my truck. She seems to be a bit more responsive and has given a small boost to MPG. I am still collecting data over a month's time of so to make certain of a few things. I am going on a roadtrip, some 400+ miles round-trip in a few hours. I will see what's going on for certain over a long, lazy 70 MPH jaunt up to Kansas City.

How did you make it? What parts did you use?

Ebay intake will give you the SAME increase and save you 150-200 bucks over the name branded variety.

Hey wolfox I read in your post about where you reset your computer after your air intake mod. The intake I bought from ebay didn't mention this and I never pulled the fuses. I have noticed better throttle response but only slight mileage increase.( maybe from using better throttle response more often?) My question is; If you don't reset the computer will It learn the new fuel mix on it's own over time? Thanks.

Are there any tests to prove this? Thanks.

Bro, its a tube and a cotton gauze filter.

The name on the side will not net you any difference in performance.

Do the no names have the larger diameter "hat" right above the throttle body? If not then it's not the same. K&N's were designed based on dynamometer testing. The knock offs may flow as good as the K&N and a side by side test would determine this. Without actual tests it's just speculation.

It doesn't matter how big the hat is.

If it is larger than the throttle bore size, it is good enough.

I bought an ebay kit.....$40 and I cant use it because the rubber collars that came with it dont fit. They are too small

Never was in a big rush to rectify that though. Sorry I am of no help here.

You do know they are probably not going to slip right on perfectly, they are rubber and will stretch over the fittings.

[Absolut Talent]

yeah, there is rubber that will stretch a little....and rubber that wont go on unless you heat it up a lot and freeze the throttle intake piece in some Liquid O2. I got the latter

[BlazerLT]

Send it back.

I procrastinate too much
bought this like 7 months ago
