This low profile and compact design were developed to allow the end user to fit under a stock bonnet. Short intake runners with tapered top are designed to increase air velocity and more evenly distribute airflow to all 8 cylinders improving performance and throttle response. We use thick 3mm (1/8") T6061 sheet aluminium for the intake plenum for maximum rigidity, so you will not have any issues with the intake manifold distorting under boost or warping during installation.

This LS intake manifold suits LS1/LS2 cathedral port heads. Powder coated black creates stealthy engine bay styling.

Each manifold is ready to bolt on out of the box and are designed to accept 102mm throttle bodies and include high flow fuel rail kit, all gaskets and hardware for a hassle-free installation.

Vaccum Ports at the back of the intake manifold:

• 3 x 1/8" NPT
• 1 x 1/4" NPT

Vaccum Ports at the underneath the intake manifold:

• 3 x 1/8" NPT
• 1 x 1/4" NPT

This Intake Manifold only comes with 3 x 1/8" to 1/8" (3mm) Barb and 1 x 1/4" to 1/4" (6mm) Barb. Block off plugs must be purhasced separatley for all unused ports.
