    Your experiences of aftermarket panel filters

    Hi all, at the moment i have a standard air filter set-up (apart from removing the bottom pipe inside.)

    I'm looking at a couple of aftermarket air filters on ebay. one courteney, one pipercross.

    what are people's findings with these?

    do they increase noise, power or anything like that?

    my car's a '99 1.8 sport

    cheers

    i used to have a k&n in my old car but i never really noticed any difference. i was wondering if courteney or pipercross were any different. anybody used this in conjunction with the vectra derv intake pipe?

    Didn't one member here test out the air filter & airbox mod theory on a RR?

    Don't quote me, but IIRC, the best gains were with just an aftermarket panel filter. I think all combos gained over standard (just panel filter, just airbox mod, panel filter with airbox mod - or whatever was tested), but that the aftermarket panel filter gave the best results.

    Was a while ago, so i could be wrong. Comes to mind for some reason though.

    £32 K&N eBay jobby for me.

    Didnt notice any noise increase but seemed to pull better, had it on nearly 3 years now and had no issues.

    I did some back to back testing with panel filters back in the day, Pipercross foam filter (same as the Courtenay one etc.) was found to give the best results which were +3bhp (that was on a 2.6 Vectra), although I now prefer a standard GM filter replaced every 3kmiles.

    all the aftermarket panel filters tend to do is give longlife compared to the paper elements, both flow well but the aftermarket one can be cleaned and re-used time after time. i have tried both, foam (courtenay) and cotton gauze (green filter) and there is no noise difference or appreciable power gains just a longer shelf life.

    The test someone did on here was with a brand new GM paper filter and a freshly cleaned k&n filter, the filter on average gave about 2-3bhp more, this was with 3 runs per setup as I remember and they were all pretty consistant.

    Just read this site panning the K&N http://www.max-boost.co.uk/max-boost/intake/intake.htm

    Listed as info for the C20LET, but i assume their view would remain throughout as they link onto Porsche's at some point also.

    Anyone reckon the link is BS?
