I just changed my air filter today. I haven't driven it yet. I'll find out tomorrow, if there is any difference in the engine performance with the K&N Air filter when I drive to church.

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.

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.
