My 05 sti has standard foam filter , what aftermarket panel filter do you recommend ?

 

I use the pro r one (pipercross) and I think the do luck one got good reviews when tested

 

Iv got a almost new K & N panel filter
You can have it £15 posted
Pm me if your interested pickle

 

K&N

 

Cosworth!!!!

 

I have a k&n in mine , does the job well, brought that one as I already had a cleaning kit.

 

Green filters are a good choice.

 

Thanks for the replies guys, there is quite a bit of choice. Don't want one that I have to oil up much

 

Cosworth one has no oil involved wot so ever and japspeed are doing them for £31 delivered at the mo!!!!

 

On their site it's £34.80?

 

Standard OEM one.

 

running an HKS panel filter in my WRX a couple days now. seems to sharpen up the engine a little but may sell it and switch to cosworth or pipercross as im not sold on the fit of the HKS filters plastic cage, took a little jigging about to get it sitting right.

 

Have been advised to get Perrin cold air intake, anyone got one of these and what are their thoughts ?

 

It's a good bit of kit, without looking i'd say they're £200+ though as well as a £200-500 remap. Then that's where the slippery slope starts..........

OEM panel filter is fine, there is next to no gain from aftermarket panel filters so don't be swayed by the big named ones.
