A BankSpeed™ product proven in the Banks Duramax Sidewinder® S-10 diesel drag truck, the Big Hoss Intake Manifolds are the only purpose-built manifolds created for a Duramax. Big Hoss replaces the factory's crude clamshell intake with a tuned 16-port manifold assembly that provides tremendous flow and uniform air distribution for more available power at a given boost level.

Includes: Twin plenum manifolds and mounting hardware; Fuel system relocation plumbing and hardware; Boost air inlet nipple fittings

For use at sanctioned racing events only

Attenion: This is for the serious Performance Customer. This manifold is NOT a bolt on and go set up. There are several major engine components that must be relocted and/or modified to accommodate the intake system such as; the turbo, EGR valve, fuel and coolant components, alternator, AC compressor and egine fan. Also, this system was designed to operate with a custom twin turbo set up. With the proper tuning this will be the most powerful and proven kit for your Duramax.
