Designed for high lift, long duration cams, this ITB design will seriously boost your throttle response and peak power/torque over the stock manifolds which are themselves very good. Runner length and trumpet design has been maximised for mid to top end power without sacrificing bottom end, of course the final characteristics will depend on other factors such as actual cam profile used, static compression ratio, spark timing and fuel type.

Injector placement has been modified to ensure best fuel atomisation and shortest path, in addition to improved valve head cooling.

It is design for a single 8mm shaft and 22x8mm bearings captured in place by a 2-piece body. Linkages are not included in this design.

For road use a fine idle circuit and controller is recommended.

Modifications required for some LS engines and custom seals/gaskets/fuel rail are required.
