K&N for me

From that list, K&N.

Or Green.

Basically one that doesn't require oiling (if still running a MAF, that is). Even then, it's an arguable point if the oil gets on the sensor and alters the MAF voltage, anyway!

ok,
so whats the best between the green cotton or k&n

Take your choice!

Just personal preference and/or price (although both will be around the 30-40 quid mark).

I have got genuine Sti panel filter. hard to find but much better than the rest..

At least they have been made specifically for the Sti...

Newer put genuine Subaru filters..

Is that not contradictory, every K&N i've used in the past 25 years has required oiling, are K&N now making filters that don't require oil? Also a green filter my mate had needed oiling too.

I've got a k n at the min but also used a jr one and noticed no difference to be honest

I,ve used K+N on my Scoobs over the last 12 years with no problems. Steve.

Possibly.

Which gives credence to the fact that they aren't detrimental for the MAF, anyway.

(K&N actually did a K&N/MAF test, etc. - check their site).

just been reading up found a test on a 05 sti and the Do-luck come up best 2bhp more than the K&N
but that could still be totally different to my93 wrx lol

^^^ Was that the Scooby Clinic test... where on the other side of the results page, there was a massive great Do-Luck advert?!

Forget it - don't get tied up in knots over a panel filter. The OEM paper filter/airbox combo on a Classic is capable of around 350bhp anyway! And it's not as if a possible potential 0-5bhp increase of a freeflowing filter is gonna magically transform the performance/drive now, is it?

Cosworth, ive lost faith in K&N after my last filter.

k&n or green for me. Used both after recommendations on here.

Had an HKs panel as well without issue either just to confuse matters!
