After installing the new filter, I picked up (see my earlier post), I finally got the chance to take a quick day trip out to Boca/Stampede for a ride. I don’t have hard numbers on horsepower or torque gains compared to before, but my butt dyno did feel a little extra low-end pull. Maybe it’s just in my head, but if not, it was a nice improvement. The Pro R already has plenty of torque, so even a small bump is noticeable.

I haven’t had a chance to see how much dirt it’s collected yet since this ride wasn’t very dusty, but I’ll crack it open soon to check. Mostly, I’m curious whether anything made it past the filter. I’ll post a follow-up when I get the time—work has me pretty tied up lately. If you’re not sure what I’m talking about, here’s the link back to the original write-up.
