i dont believe in cold air filtersetups on turbocharged/supercharged applications. however as far as a filter goes a oil impregnated cotten (k&n) is going to give you much better filtering then something that uses a foam element such as a greddy or blitz... things that use a small metal mesh are just crap and for looks.

So the blitz system is crap?? I remember reading something where they filtered better.

I have yet to hear of an engine or turbos dying from lack of filtering. Even some single turbo guys run without filters.
Just get the intake you like they best. The difference is really in "what you like", not "how they perform". They are all pretty much the same aside from minor fitment problems with aftermarket ICs.
Having said that, for stock twins, the Blitz looks the best under the hood IMO.

Also a side note, i just spent 15 minutes looking for info on filters. too much bias crap on the internet to prove this argument either way.

unfortunatly you would never know that it was improper filtering because it causes degradation over time.

On a turbocharged car, IMO, it's not that important (unless as you said, you are throwing bolts into your intake). With NA cars, it's a little more important.
However, there is a price for filtering as more efficient filtering means less air. There is always a trade off.

I have the blitz sus as well and its the best looking filter out there.Its also the most durable as it is stainless steel mesh not foam or paper which over time degrades a lot faster than the blitz units.Im very satisfied with this intake system and recommend it to anyone with an fd or another car that it fits on.Im also confused as how a bolt wound up inside your engine.The blitz units have no such opening to allow something like that to enter your engine.

Well based on the article it does seem like the apex one is the best as far as filtration goes.As far as looks go both the blitz and the apex are the best looking and as far as the horsepower gains its clear that theyre damn near identical.blitz 13.9 the apex 14.0.Not much difference at all in my book.But I do like the blitz better as far as overall looks go.

It is questionable how accurate the original source of data is, as HKS are proven to sell more induction kits than any one of the others featured in the test, and yet there induction kit rates as the worst kit in the test. This suggests that either HKS rely upon their brand name to sell their 'poorly' manufactured air filters, or that the original Japanese test was nothing more than a PR stunt to promote the lesser known equipment. HKS and Blitz continue to be the best selling induction kits in the UK, and are used by Middlehursts, Hiteq and Abbey Motorsport as their first choice when the induction kit modification is carried out.
They didn't do the tests themselves. The data was provided to them.

I read on the K&N web site that air-entrained particles 10 to 20 microns in size are the most damaging to your engine. It appears that K&N filters are capable of removing material as small as 5.5 microns in size. You can read more about air filters than you ever wanted to know by clicking on the link here:
http://www.knfilters.com/facts.htm
If the K&N information is correct then the Blitz filter and others like it are only for show and are effectively useless as filter. I know that many members use minimal, or even no, filtration and claim there is no downside. I find that hard to believe given that every auto manufacturer in the world equip their cars with air filters, including the high performance types like Ferrari.
