intake question

[dmurph12]

I bought my truck with a complete k&n intake system and I want to replace the filter as ive heard bad things about them, my question is can I use the napa filter with the k&n intake elbow?

[bruce51d]

the napa filter has a 4" inlet, i'm pretty sure the k&n is a 4" tube

[dmurph12]

I think it is a 4" tube, so I should be good?

Yes you can. That was the set up I was running up until a week ago.

There is nothing wrong with the K/N filters on there kits. Its not an issue with the filter on there drop in's. Its the way it seals or for a better word, does not seal to the factory box.

Seems most folks would disagree with you about the K&N. They don't filter small particles as well as the 6637 filter does.

Then they are uninformed and mistaken.
