K&N 57 Series FIPK Air Intake (50-State Legal) - 57-9025

Great Intake. Clean install. Acceleration dramatically increased. There is a small whoosh sound from the intake during quick revs, but I love it.

I love it! Noticed more horse power and deeper sounding.

Very high quality craftsmanship, fairly easy to install. Not much change in engine noise so if that is your main goal you would probably be better off going with an exhaust system but there is a noticeable mild increase in power, especially at higher RPMs. Street legal in California

K&N provides 2 brackets to relocate the secondary air pump (which weighs about 3-5 lbs). There are 3 connection points on the air pump, it's mounted on rubber and requires 3 connection points to mount it securely. K&N designers expect the air pump to be mounted at two connection points which leaves the weight of the air pump suspended and with time and road vibration it will break. Imagine the stress on the connection points going down a dirt washboard road. I went back to the stock intake.

Easy installation, Great Quality. Had an issue with 2 bolts being too small when installing the heat shield also Intake was not as pictured. Had to use OEM air filter box less the filter. I was expecting the intake tube to connect directly and delete the OEM Air Filter box..

Overall, the K&N air intake system looks great. The throttle response on 3rd gear (around 3000 rpm) is smoother. On the other hand, the installation guide was vague. The secondary air pump wire was little short on new the relocation site.
