Greenfilters kill K&N's.
Maybe my butt dyno is off, but it appears there is a detectable difference in the two. So much so, that I threw the K&N's away after one banzai run. Acceleration is markedly quicker than my old dirt clogged paper AMG filters. Now for stealth exhaust tweaking.

Yup, especially in a car that weighs over 3500 lbs. The throttle response is the most marked improvement.

Does anyone have real numbers? I am very skeptical of any one's feeling - especially after they just spent a bunch of money.
What I am saying is that the only thing that matters is the dyno. All other data is not accurate, in my opinion.

For what it's worth, I have real numbers for K&N filters (no other mods). The dyno runs were performed the same day, about an hour or so apart.
Pre-K&N HP: 297.6
Post-K&N HP: 298.2
Pre-K&N Torque: 292.9
Post-K&N Torque: 296.0
Note that my original filters only had 1000 miles on them at the time. Had they been "old dirt clogged" like the original poster perhaps there would have been a bigger difference (with the Pre-K&N number being lower).

You can't just make a mod to these cars and make one run up the street or one dyno run and get any indication of whether it made a difference or not. It takes many runs and miles for the computer to learn the mod. I doubt there is much difference between the K&N and the GeenFilter sincee the GreenFilter is just a copycat of the K&N with green instead of red cotton gauze.

Someone here posted about a blowdryer and floating ping pong ball test that was performed back to back with a greenie. Apparently, the green filter allowed the ping pong ball to be pinned to the top of the chamber. A crude flowbench, but none the less convincing. That coupled with Renntech's adopting of them is what made me dump the K&Ns for Green. The seat of the pants just confirmed, albeit subjectively, what was already posted. Could be placebo effect, but I didn't subconsciously feel the need to get my money's worth. I'll see if I can find the ping pong ball post.

haters crazy
They have a website, check it out www.greenfilterusa.com I just ordered a set. I'm going from ITG filters to Green. I also have a renntech airbox. The people I bought mine from said they have 15% better airflow than K&N, but remember the source is a green dealer.
