K&N or Pipercross?

[Khare]

Just to through another one in the mix,i have a green cotton filter

Not hear much about green filters, but being cotton I assume they are the same as the K&N filters.

what sort of gains do you get from the filter?

30% more airflow than normal paper filters so it says.

Realistically, I got louder intake sound, better throttle response, more MPG, and better pick up on the revs.

agreed tbh its one of the best things i fitted cant rate enough also the pipercross filter doesn't need oiling its dry foam according to the box mine came in just requires washing with recommended cleaner,dry and then re-fit 

Not true you need to spray the pipercross dirt retention fluid on or it wont work as a filter, too much though and it will block the airflow.

supposed to be a good filter by all accounts  anyone fitted ITG ?

[snap-on]

Green cotton was the best recommended for the 03- wrx so i got one and certainly done the job !

i was gonna get a kn panel for my aum but there around £50 where as pipercross are around £35 so it maywell be the x for me .

Has everyone who has replacd thier filter also smoothed thier air boxes?

I cant be ar*ed to take it all out and smooth it - can it be done in place by just removing the lid?

smoothing the box is easy!.. but i aint put the r32 intake pipes in so cant comment on them... iv just smoothed my box and put a pipercross in 

when are you suppose to clean the pipercross panel filters anyway?? i never got any spray or anything with it as lads from r-tech put it in for me   

[tariqb]

that still doesn't resolve the question  - - why piperX is better than K&N or vice versa  - what distinguishes one from the other, some technicalities please.

[gtigolfthree]

I think K&N have the edge because they are not as good at filtering, an air filter as its name suggests has to filter sh*t out of the air without restricting air flow, a contradictory task. K&N I think were developed for racing cars running in fairly clean air where as piperx were developed for motorbikes especially motx and rally cars where the air is dirty. What is more important to you, a longer engine life (piperx) or slightly better air flow and performance (K&N) unless you are in a dusty area K&N should be fine.

k&n are good i dont like pipercross ,just what i think......
