20B Lower Intake Kit with fuel rail **SHORT**
Xcessive's all new cast lower intake manifold for the 20B is based on the same concept as our original 13B-REW manifold, better runner flow balance, more volume and more fuel. We've made these manifolds with 6 injector bosses machined to fit Bosch type top feed injectors with 14mm o-rings without any adapters. We've placed all the injectors on the inside of the manifold to keep them away from heat leaving more room on the outside for turbo motors as well as a cleaner install.
The new lower manifold fits stock upper castings and comes in both a full height (stock) and short versions. **This is the short version**, it's 1 1/2" (38mm) shorter than stock (full height). They are also available with and without fuel rails. This manifold kit includes the fuel rail assembly. The fuel rail has 3/8" NPT ports on both ends with a -8 (1/2", 13mm) through hole and comes with the apropriate stand off's for full height top feed injectors. No more welding bosses onto a stock manifold and chopping and welding the upper flange, we've done it all for you in a single brand new piece that'll also out flow a stock manifold.
