K&N RK-3906 Intake System-Honda Product Reviews

Sunday, June 29, 2014 - Part RK-3906
Overall great product! The kit comes with everything needed and good instructions. I only knocked it down one star because I think a company like K&N could have made a filter exactly the right size. It does take a little work to get the filter and cover on.
