Yep, what Monte said....Torker is old school, there are much better intakes out there. If you must have a single plane, I would use (and have used) Team G.....but the Performer RPM is great, you can get the regular one, or the air gap...the air gap looks a little more like a single plane, has some space underneath it. A dual plane will work better for you on the street, especially at lower rpms. You wont see a difference on the street between a 650 and 750, so if that's what you're looking for, spend your money somewhere else. And stick with a vacuum secondary, dont go with a double pumper on the street. It will be crisper responding.
