Features & Product Details

Cosworth's High Flow Intake Systems feature increased surface area of the element, large smooth radius bent aluminum inlet tubes for superior air flow management coupled with a high flow air filter for maximum air flow and performance.

Each kit includes an integrated heat shield designed to isolate the air intake from engine heat - delivering cold air into the engine for superior power conversion. The filter element is large, conical in shape and engineered to dramatically reduce intake restriction resulting in additional power and torque.

      A:  This is a direct factory replacement unit. So if your inlet works with stock airbox then it will work with this intake.

  • Q: Compatibility  jindajiver6 years ago

    Will this work with the AVO Silicone turbo inlet? Thanks.

      A:  Hello, unfortunately this intake will not work with the AVO inlet. The AVO inlet has the post MAF hose built in,and this intake requires the removal of the post MAF hose. Thanks.
