THE JQRacing White Airfilter Holder
THE White JQRacing Airfilter Holder includes the filter housing, and filter neck. I remember when designing the arifilter I had no idea how much bigger the foam should be than the holder itself. It is these small things that just stop you in your tracks. I had never even considered the issue, but it is clearly and important one. Use high quality air filter oil, on both the inner and outer foams.
