Panel filter

Recommended Posts

i always rated k&n's had one in my old astra gte for 60 k just got one for my polo gt but when i got the corrado 5 years ago it came fitted with a jetex cleaned that a couple of times same make up as the k&n oiled cotton never used the foam type like pipercross etc so can't comment on those

 

 

think it comes down to how much you want to spend second hand ones can be cleaned and reoiled to perform like new k&n's have a million mile warrantee so they will outlast a few cars if cleaned and oiled regularly

i've got a pipercross on my 16v with the airbox drilled and all seems to be ok, previousaly had a K&N in it without drilled box so dont know if there is any sound difference between them, but again ran ok.

Thank's. U mention oil. Can u tell me what that is for ?

 

the filter is sprayed with special thin oil to help it work better (you can buy a kit of cleaner on oil to re do it )

 

as for bhp gains on a standard car no more than 1or 2 bhp at some points on the rev range you sometimes even lose a couple of bhp at other points but it does seem to allow the engine to rev more cleanly and pickup quicker but having just spend £40 on something you can't see you have to tell the misses something :lol:

intake noise will be a little louder normally also

 

don't believe the claims of 10 - 15 bhp with a filter alone just not there on standard cars
