While developing the intake plenum for the H1, I decided to offer the same plenum for Hayabusa bike engined cars. This is done by providing a different 4 hole back plate. Additional pictures are on the Engine gallery page.
The intake plenum can use standard Hayabusa velocity stacks or billet ones can be provided as shown. The Billet stacks are 42mm long.
Price of the Intake plenum with back plate, and 70mm (2.75") flange adapter is... $300.00
Price adder for billet velocity stacks and special rubber seals is... $160.00
(This is a special package price as they normally sell for $200)
See the contact page and email me if you are interested.
The billet velocity stacks will also fit the Hayabusa airbox and can be purchased by themselves from Schnitz racing. See www.schnitzracing.com
