supRo Posted January 18, 2006 Share Posted January 18, 2006 Now we all agree that alot of aftermarket filters are poo at filtration. My question is why do alot of highly tuned cars use the HKS mushroom style filters for example? I'm sure these tuners (you see pictures everywear, just look at the jap tuning mags) know what they are doing, yes they could probably re-build engines as and when they please to but surely for the sake of an air filter, they wouldn't want to do an engine rebuild??? Just seeking knowledge so be gentle! Please discuss! Thanks, Ro Quote Link to comment Share on other sites More sharing options...

Jake Posted January 18, 2006 Share Posted January 18, 2006 As I understand it, the stock airbox and filter are not a restriction until about 500BHP. All the cars you're talking about make way more than that ....or claim to Quote Link to comment Share on other sites More sharing options...

All the cars you're talking about make way more than that ....or claim to yes, but are they (tuners) not concerned at all about damage from the crappy filtered air? edit to say: Surely K & N/apex-i style filter (cotton) would have been the obvious choice?

mr keef Posted January 18, 2006 Share Posted January 18, 2006 I have thought about this too,A massive company like HKS with all the testing etc,and some people say there filters are shite.To be honest i dont believe that,i mean yea stock airboxes are awsome on some cars like the supe,but i aint seen many cars that are tuned,or in magazines etc still with standard airboxes.Thats not to say follow the sheep,but with every car i'v had airfilter and exhaust have always been the first engine mods.And i dont think Hks would make a filter that doesnt do the job....But thats just my opinion Quote Link to comment Share on other sites More sharing options...
supRo Posted January 18, 2006 Author Share Posted January 18, 2006 As many will say, alot of aftermarket products are there just to sell stuff that makes the companies money but doesn't really benefit the car e.g. the hks cam gears which have sheared cam belts. So why do these respectable tuning houses use the mushroom filter???!! Quote Link to comment Share on other sites More sharing options...
mr keef Posted January 18, 2006 Share Posted January 18, 2006 People buy Hks for a reason if there stuff wasnt up to scratch...tuners wouldnt use them.....and people wouldnt buy them.....and they wouldnt have a buisness.... Quote Link to comment Share on other sites More sharing options...
Jake Posted January 18, 2006 Share Posted January 18, 2006 But are those cars built to do real world high mileage. They aren't exactly daily drivers - even the ones that claim to be. Does Terry S run with a HKS filter? Does Matt H, Does Ian C ? Leon? Quote Link to comment Share on other sites More sharing options...
supRo Posted January 18, 2006 Author Share Posted January 18, 2006 Alot of members have these (so did I!) and judging by the aluminium piping that usually comes with it, you can tell that they've been on the car a good few years (pitted/oxidising) but the cars are running absolutely fine!

mr keef Posted January 18, 2006 Share Posted January 18, 2006 I aint saying the HKS is the best filter,but i doubt its the worst,the japanese seem to love the Hks filter Quote Link to comment Share on other sites More sharing options...

RobSheffield Posted January 19, 2006 Share Posted January 19, 2006 im sure the K & N ones would be better on the highly tuned single turbos. iirc thats what Terry et al use. a lot of the big singles (both Supra and Skyline) that come over from japan ready tuned have HKS on, because they buy into the marketing blurb over there!

That would put the world-wide supra question of the stock box being better than an induction kit issue to rest forever Quote Link to comment Share on other sites More sharing options...
supRo Posted January 19, 2006 Author Share Posted January 19, 2006 I totally accept the stock air box is good for upto 500 bhp'ish and people have to junk it when goin single. But still not convinced that HKS mushroom although not great at filtration -Is it really that bad for your car? Quote Link to comment Share on other sites More sharing options...
