Why Upgrade?

From the factory, your VQ’s intake plenum is restrictive. By porting the runners and throttle body inlets, airflow is significantly improved — resulting in more horsepower, better mid-range pull, and harder top-end power. Combine with bolt-ons and tuning for the ultimate street or track setup.

Upgrade your VQ the right way with the Initiate Motorsports Ported Intake Plenum — proven gains, precision workmanship, and performance you can feel every time you hit the gas.
