Thumbs up Just installed HKS drop in filter.

All I have to say is that I'm impressed with what this filter did for my car. No break your neck type of stuff, but there's definately a little more 'oomph' with the acceleration.

Not bad for 37 bux.

Looks like the stock paper filter, except its green foam like the HKS mushroom filter.

How does it compare to a K&N?

Don't know how it compares to the K&N, so I couldn't tell you.

Leo, damn, I forgot to get the part #, but I got it off of ebay anyways, and I think the guy that was selling it bought it in Japan and brought it back here to sell.

I've had both the K&N and HKS filter and IMO, the HKS flows just a wee bit better, but it also gets dirtier quicker, hence more maintenance.

BTW, the HKS drop in filter has the usual HKS dual stage foam element.

Another alternative for those that can't get the HKS is the Amsoil which is basically the same thing, but you lose the green color and the HKS bragging name.(hence, no justifiableb "Powered by HKS" decal)

I've read a few different articles which indicate that the performance of foam filters will quickly diminish as they get dirty, since the pore will quickly clog. In some cases, prior to being cleaned, the flow is actually worse than the stock paper element. I wish I could remember where I'd read this. I know it was a fairly independent source, not K&N.

The K&N filter, according to them, anyway , will continue to flow well even while dirty.

I'm not sure that that reassures me. Does that mean that it is letting dirt through? How could it flow that same while dirty and not be letting some bad stuff through? I think that I would feel better knowing that even though my performance started to slip, at least my engine is well protected.

IIRC, the foam vs. gauze filter issue is covered in cobbtuning.com .
