    also for reference green filters are apparantly the no1 air filter in world motorsport lol how true that is I don't know but thats what it says on there website

    I have a heat shield already and looks like k&n will be the choice of filter due to the difference in price

    Thanks though, some real hood advice there!

    i don't like K+N, i used to have a few vauxhalls running them and i didn't really get any good results from them, in fact 1 of them i replaced quite quickly due to dodgy idle and cutting out!
    from there i went to pipercross, they were good, k+n cones are crap, never will i ever use 1 on a car that has it under the bonet!
    i have also heard good things about green cotton filters, and i think the price reflects that, its also good to point out that K+N have some filters that are quite expensive! and these are the 1s used by the tech guys, not the cheaper 1s found on boy racer cars, but i have never sampled these!

    green filter for me!!

    well I have got the K&N.. working with a heat shield so lets wait and see what happens, if all goes to plan then happy daises

    If not then Green hulk all the way (Cotton filter)

    Tbh my buddy in his MX 5 had some issues with his K&N set up... mainly because of the lack of a heat shield so fingers crossed

    They are all doing the same job - les restrictive filter is more power gain and more microparticles sucked into the engine = more damage to the engine in longterm using.
    My solution - keep the original filter for daily driving and use sport filter when you need more power ( track day,...).
    I like the green stuf me.

    I had an Apexi on my MR2 and came across this article at the time:

    http://www.mkiv.com/techarticles/filters_test/2/

    bit of any eye opener if you compare it to similar style filters on the market!

    Personally I'd go for an Amsoil filter: http://forums.evolutionm.net/evo-eng...t-results.html

    they do them for our cars and are low/no maintenance - although pretty rare this side of the pond!!

    if you're any good with Japanese you can read the original test results:

    if anything it should give you an idea of how the different types of induction kit perform (i.e. dry, oiled, mesh, sponge etc)
