i have just bought a 133 and im goin to put a new air filter in, and what ive heard is that green air filters are pretty good so what i wondering is where can i buy one from and how do i fit it haha
I have a BMC on mine (albeit a GT not an RS) and its great, cannot comment if they are as good on the RS though so i will leave that to those with experience
Both BMC and green filters are hand made so you don't get as much rubber seepage from the frame onto the filter compared to other manufacturers. Both are top notch quality so you can't really go wrong with either.. BMC ones tend to be the more popular choice though
