38 Motorsports Air Induction System (AIS) block off kit for the Yamaha YFZ450R.
This kit includes- Block off plate, zip ties, vacuum cap, and wiring harness delete plug.
YOU WILL REUSE YOUR OEM BOLTS AND GASKET.
THERE WILL NOT BE A CHECK ENGINE LIGHT CAUSED FROM THIS BLOCK OFF KIT.
Removing the AIS system is a near necessity on the 2014 and newer YFZ450R. It lessens the popping on deceleration dramatically, and really cleans up the front of the engine. It is available in several color options that all include an etched 38 Motorsports logo, adding some functional bling to your quad.
Although designed for the 2014 and newer Ais block off, it can be used on the 09-13 models as a simple bolt on bling piece.
Perfect to pair with the 38 Motorsports breather box to make the install of both parts easier and less time consuming.
You can also pair this with our 38 Motorsports tank lowering collars to remove the entire plastic tray that the AIS mounts to.
THIS PRODUCT IS FOR CLOSED COURSE USE ONLY.
