those foam filters (like hks) have really good flow, but their filtration is something to be desired... especially after running for awhile as the foam sucks in and moves it creates gaps for dust/dirt particles to get through...

theres an asm article on best pod filters within budget. hks rated pretty low. just incase anybodys interested 3A racing rated the best =]
damn thats pretty bad. lol i had mind for about 15,000km and its a alot cleaner. yours is a modified box ?Quote:

as was said before there was probably some under table dealing with the asm test as the local filters rated best.hks rated something like 8 out of 10,because they said it flowed less and was dirty as.sure it does let alot of dirt through because of its foam design,but no way does the 3A flow more than it,even if there dodgy test says so,the hks you can see through the holes in the foam are so big,the 3a is cheap finely woven metal.Quote:

different areas of driving.10000km in the city is nothing compared to 100km in dusty conditions.just give it a clean and oil and its good as newQuote:

i know this post is old but feel it right to correct it...Quote:

this also applies to any car that uses an AFM.... fortunately for hondas we run a map sensor...
Do our Hondas use such a MAF? Or rather a MAF which is positioned where it is prone to oil contamination from the K&N?
K&N cleaning kit will fix that right up
just so people dont flame me if i say yay or nay,being a mechanic by no means makes me an air filter expert....omg i wonder if some sick bastard has that job.Quote:

if your company makes lightbulbs,chances are your gonna be pretty bloody good at making lightbulbs....k & n make air filters,not like hks,3A, etc etc who make a huge range of parts,so k & n know what they are doing and they have the mix of performance and engine protection pretty much spot on
hondas use a map sensor (manifold absolute pressure sensor), not a AFM (air flow metre) or MAF (mass air flow sensor).so we are ok.correct me if im wrongQuote:
