Blow off valve / Wastegate

The standard BOV does not do justice for the H2. Lucky, Extreme Creations has a plug and play piece. The standard BOV weights 352g. 

And no longer requires the oem hose which returns purge air back to the air inlet. This was the design that deadened the noise. This hose alone weighs 328g (excluding can) making the total weight to 680g.

This fat oem hose will disappear. And is a PITA to remove. 

OEM air inlet has the holes plugged off. The hose on the far left connects to the engine for the breather circuit. 

Crankcase breather for your info. Planning to make a independent breather kit at some point. 

To remove the oem purge air hose, you need to remove the airbox plenum. Not sure why Kawi added this wire mesh and tall rubber vstacks. I ditched them all. This saves another 201g. 

Installed the Turbosmart BOV and the pisshhhhh is now superperb.

Its a less complex kit, and in total  contributes to a savings of 497g.
