2011-2013 Yamaha FZ8 AIS Engine Block Off Plate

Fitment 2011-2013 Yamaha FZ8 *For race/off highway use only. Description Our kit is the perfect, no-fuss way to eliminate bike's factory air injection system. The factory system has several drawbacks including making it difficult to properly tune your bike. Drawbacks are due to the "fresh" air being injected into the exhaust causing O2 sensor readings to be incorrect. This modification also significantly reduces the ignition of fuel vapors (backfires) in the exhaust systems. It helps you to preserve your expensive exhaust system and prevent damage to the internal muffler packing. CAD engineered for precise fitment and CNC machined from 6061-T6 heat treated billet aluminum for strength. Prevents warping from high engine temperatures which could lead to vacuum leaks. The plates have been anodized black with a hi-temp coating. Promotes a better surface seal and also provides a clean, finished look. Also included is a vacuum cap for the lower air box port. Prevents unfiltered air from entering the intake system. Our kits are high strength and integrity. Comes with full installation instructions and installs easily.
