because the plastic ones bend and let in un-metered air... :)

I have an A'pexi which, in tests was shown to be the best on the market, so I'd steer you towards that one. It's quite expensive against the competition.

I run a JWT pop charger, must admit it work well and can be cleaned and re oiled

HKS on mine which is great but it does not like the rain and definitely stay away from floods!

 

Apexi all the way ? incidentally, I have one for sale!

I have 2 jwt 's for sale, brand new. Bought for mine but won't fit given new plans

I had many a discussion regarding Apexi filters years ago, and I believe the test you refer to is covered here: http://mkiv.com/techarticles/filters_test/1/index.html & http://mkiv.com/techarticles/filters_test/2/index.html

 

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.

 

The test was conducted in 1999, and doesn't bear any relevance to today's filters 16 years on, as designs & materials have changed. Back in the day, the Apexi was dirt cheap to buy compared to the others. I had one on my S13, but was not a fan and there is a long thread on SXOC way back March 2007.

 

This was the Apexi filter that was actually tested:
