The Hellmann Billet Intake Manifold is the original one-piece side draft intake manifold. The innovative design was initially created to solve the issues stemming from porting and polishing process on the intake side of the cylinder head.
To properly perform this function, the cast manifold must be cut off of the cylinder head, leaving no way to secure fuel components and intake piping. The Hellmann Performance Billet Intake Manifold will secure to the side of the cylinder head taking the place of the preformed restrictive cast piece. The Manifold is designed with performance in mind; enlarged intake entrance ports are much less restrictive than stock creating superior air flow.

Hellmann Performance’s Billet Intake Manifold is constructed from a single piece of aircraft grade T6 billet aluminum. It is cut to exacting specification in a state of the art CNC machine. The Manifold is predrilled for fuel rail installation, and comes with high grade stainless steel hardware. All predrilled mounting holes have been painstakingly measured to ensure perfect fitment of all OEM fuel components, including being able to accept dual CP3 injection pumps.

The kit also comes with a prefabricated intercooler pipe, v-band clamp, and return line fittings. Manifolds are designed for 2003-present Dodge 5.9L and 6.7L Cummins Turbo Diesel engines.

The pipe & inlet size is 3 inches.

The Hellmann Performance Fuel Distribution Block eliminates the mess of fuel lines associated with dual CP3 systems, or aftermarket high volume fuel pump. (ex. FASS, Air Dog) Once a dual CP3 system is integrated, fuel lines are a mess in the engine bay creating confusion. If running a FASS / Air Dog high volume fuel pump system, OEM canisters are normally the first thing to go. The Distribution Block is designed to mount in the OEM position of the fuel filter canister. The Distribution Block is intended with choice and option in mind.

It is machined with three ½ inch NPT fuel feed ports, five 3/8 inch NPT fuel return ports, and two 1/8 inch NPT fuel accessory ports. The block is machined from aircraft grade T6 billet aluminum, includes mounting hardware, and 2 fuel port block off plugs. It is designed to be used with Dodge Trucks equipped with Cummins Turbo Diesel engines, 1998.5-2007.

By: Hellmann Performance

Running lots of boost? Oil leaks from the crankcase breather system on your Common Rail Cummins engine? Tired of your engine bay looking plain? Enter the Hellmann Performance Billet Valve Cover – solve all of these problems at once. This valve cover was originally introduced to solve issues stemming from high boost applications and a very restrictive crankcase breather system. The OEM crankcase breather seals are prone to failure, and spread oil all over the engine bay. The Hellmann Performance Valve Cover System uses dual ¾ inch crankcase pressure outlet lines (rear of valve cover) to flow into a custom fabricated oil catch can. The bottom of the catch can is designed to return all oil back into the oil pan by utilizing the factory oil return location. 

The Hellmann Performance Billet Valve Cover System includes the Valve Cover, constructed of aircraft grade T6 billet aluminum, the custom fabricated catch can, crankcase breather lines, hose extension (to tie into factory oil return line), clamps, fittings and all mounting hardware. The Hellmann Performance Billet Valve Cover Systems are designed for 2003-Present Dodge 5.9L / 6.7L Cummins Turbo Diesel engines. 

03-04.5 Trucks Have the "Wavy" valve cover like pictured.
If your 04.5-07 Truck has the straight edge valve cover, select the 05+ option below please.

Includes billet oil fill cap!

Substantially more crankcase ventilation for high horsepower applications.

Please allow 5-7 business days before shipment!
