Product Description
This 3 piece modular intake manifold by Skunk 2, allows for easy disassembly, porting, and plenum volume changes through the use of a removable plenum. The design is one of the least restrictive out there, yielding both torque and power gains well over any other offering!

Using a large 68mm throttle body opening and constructed with thick walls at entry, this manifold minimizes concerns of breakthrough when port matching. The 1.8L plenum volume manifold will distribute even airflow to all four cylinders under dynamic load conditions. Furthermore, placement and design of the velocity stacks were rigorously flow tested to ensure maximum delivery of air to the cylinder. With 10.00” long intake runners with smooth transitions, it will allow the Ultra Street Intake Manifold to outflow all other production intake manifolds.

Note: This manifold was designed to be used in modified naturally aspirated applications as well as mild turbo/supercharged setups.
