Just installed a True Flow I got from Jason B. Haven't had a chance to test drive yet since the wind is blowing like a B so it would be real hard to tell if performance was gained...
What I can tell you is that this filters frame is a rigid as it gets...It fits the Airbox very tight...no dirt or air will get around the frame of this filter. At first I thought I had it in there wrong. Checked and double checked...It just fits with really close tolerances! After all thats what you want anyway.
Looking forward to driving tomorrow.
