So I am wondering. Do I run an air filter or just use a screen on the compressor inlet? I am reluctant not to filter in a street car although it will have limited use. But then I am thinking a filter to flow the air properly for high bhp might be a struggle to get? I have seen a lot of builds with screens or nothing at all but not surenif that is how they actually end up being driven or if that is just for dyno and pics.
Thoughts?

 

if you run no filter you don't deserve to drive it.
Always run a filter...ever seen a sand blasted impeller...if not you will soon.

personally, run some good ducting and select a good panel filter and plumb it up to your turbo.

 

I have never not run a filter! I only asked as I see lots of builds that appear not to!

Answers my question though. I think I will need to find a decent cone filter as I am starting to struggle for space in the bay now to mount panel. I am thinking about putting a vent/hole in the bonnet to feed it directly outside air.

 

K&N has their catalog on their website. They have pretty much any size/shape of cone filter you could want. They will also make custom ones for you if needed, not sure of the cost.
