Do they work? I tried the cr10ek plugs and I could feel the difference and even swapped back and forth between the cr10's and stock to be sure .
Do the air box mods really work and who has the best kit?

Fix Powersports brings in the coldest air and the most air and cold air is what makes hp and yes it works, just not as much as they claim, but I think it works better than anyones.

hands down, ulmers, cheap and as quiet as stock! fix's lid is pretty loud imo. just crack the front of your air box and crack on it a few times, some people like the sound but i personally dont care for it. i installed a box like ulmers and i felt the difference imediately
