Whats the best free flowing panel filter on the market as I find k&n ones get blocked quite quick with stuff in the v grooves any better ?, dont want induction kits as its a NA car and they sound gay

Surely the quicker they get clogged, the better they are doing their job? If a certain type of filter stays cleaner longer, then surely it is passing the muck through it...

K&n and piper cross are the only panel filters I would use, and as said they clogg for a reason as there not letting too much past, do you use the oil cleaner?

I know what you mean guys as I swore by k&n for many years but on my focus it seams to clog up way too much and yes I know its doing its job but opening up the airbox every few weeks is a pain it arse big time to brush the grooves clear, induction kits on NA cars is nearly all about noise and looks plus im too old for that bollocks, so im leaning towards pipercross as they mention the problem I am having with k&ns in their advert so lets see what £35 brings

A standard clean paper element is the way to go on a fairly standard car.
That filter much better and have far more surface area.
I've never had any good results from a panel filter.

I have bit the bullet now and bought pipercross so will see if it pans out better than the k&n on the plus side I sold the k&n for £25 = result

Yep, OEM and change often if there are concerns

can u not airline clean it, takes two tics,no brushing needed?

due to having a very free flowing exhaust I needed a decent fast flowing filter which is what made me go away from paper, but I will give the pipercross a go and see how its pans out in comparison to the k&n, as for the airline yeah of course but evey few weeks was getting tedious

An airline will fuck a panel filter as it will blow holes in the foam. To clean it use a soft brush and proper panel filter cleaning solution.

Have you tested the OEM setup to see if it poses any restriction ?

Most modern cars flow very well, over and above what the engine needs, plus you get the added bonus of proper cold air feeds.

yeah it was dyno'd not too long ago after fitting the decat and k&n and it had a tweek on the ecu too so all was as it should be Im using the OE filter box with a 2nd cold air intake so it was set up for this by the tuner and runs like a dream
