This blow off valve block-off kit includes an aluminum block-off plate, o-ring, and v-band clamp. It’s used to cover and seal off the 50mm blow off valve flange in the event that you decide to not use a blow off valve on your setup. This block-off kit is compatible with the 50mm flange that is included with certain Fizzle products, such as the Fizzle Yamaha Intercooler Kits and select Fizzle blow off valve kits for Sea-Doo and Yamaha. This vacuum adapter kit allows you to easily connect vacuum reference lines for performance accessories such as blow off valve kits, boost gauges and rising rate fuel pressure regulators. This adapter directly screws into the factory intake manifold, eliminating any need for drilling or modifying the intake manifold or other methods like splicing into the MAP sensor signal. This kit includes two 1/4” barbed fittings and one 1/8" barbed fitting to fit a variety of accessories. It also includes 2 block-off plugs in case any ports go unused.
