interesting reading cheers

 

I've said this for years.

This is why for example, Prodrive will recommend an ITG panel filter on the scooby, as it doesn't destroy the AFM like a K&N will do..............

 

may as well not bother with one at all if you've got a hks, that's shocking filtration! what's fitted to yours then?

 

The worst one was the HKS foam filter which is probably the most popular

 

I got a HKS type filter for my RST, fuck....anyone wanna buy it? I dont run one on my Pug Derv.....feel the powwwwwer

 

i heard k&n work better mucky

 

Basicly its not the make, its the TYPE of filter regardless of make.

Foam ones are just plain shit, may as well just scoop up mud n thow it into the engine My car came with HKS filters. Thats why i sold mine to IMA

Metal ones are pretty bollocks too.

But cotton ones are good

I got 2x massive "GrpA" Cossie K+N cones with alloy trumpets to go on mine now, for just 1 turbo, lol.

 

ITG are foam...

 

I knew the HKS was shite! but was th eonly pissin thign i could find that wold fit on the esccy!


Phil u shoudl b able to get a monster cone on yours!

 

arnt the apexi ones meant to be bad for flow hence why they let the least dirt tho??

 

I once read a filter test by Dave Vizard in which he tested all the popular manufacturers filters and filter types, from paper to foam.

The K&N filter came out tops. There wasn't a huge amount in it between the top filters in peak flow but he also tested the filters again after 1000 road miles and the K&N was out flowing its rivals by a huge margin! Seems as the K&N gets dirty its performance doesn't drop off nearly as much as its competitors!

I would go for K&N every time. Very easy to wash and re-oil.

 

........ but not covered in oily shit that kills the MAF sensor

 

Rich,

I wasnt critisising ITG at all - i know they're good filters.. I was commenting to whoever said that all foam ones are turd lol

 

I've seen the effect of the HKS ones on a Skyline - it needed two new turbos .

 

@ Mike, fuck...lol....hmm, anyone want it?

I fancy a huuuuuuuuge pipercross one really, but very pricey and still foam

 

on k&n and others, it's not the filter itself that picks out the dirt, it's the oil. that's why you should clean them and re-oil them properly.

 

are skyline afm's hotwire type? these are one of the most delicate parts on the entire car.

 

Phil itg do hoooooge 1s for cheap! (Hoopers) did u c the 1 i had for mine b4 i got the tubular manifold!? was mooooooosiv!
