I'm looking to get a good intake system for my 4.6. I was thinking either K&N or Air Raid, or Air Force One. My question is will this affect my exhaust system. The reason I ask is because when i put a K&N air filter in my truck my O2 sensors went bad 3 months later. Im not sure if the filter caused this but I wanted to make sure. Any advice or suggestions would be appreciated.

 

The only reason an air filter would cause parts to fail would be if the filter was over-oiled.

Otherwise, it was just coincidence that your O2 sensors went out shortly after upgrading.

 

any thing ur intake would suck in gets burned up during combustion so its most likely its just a cionsidence

 

thanks i appreciate it. At that time i hadnt oiled the filter so that wouldnt have caused it but i guess just coincidence. Thx. So i guess i'll go ahead and get the intake.

 

get the AF1, its pretty dope, and looks trick!

 

i bought a cheapo off ebay 3 years ago and its holding up perfect. i made my own heatsheild out of some stainless saves myself 200 bucks.

 

did you get the same kinda power from the cheapo though?
