  5. SpeedCircuit 8 Injector Intake Manifold

    SpeedCircuit 8 Injector Intake Manifold

    $999.99

    Running a lot of boost? Need more fuel in your engine? Here's your answer. Included with this manifold are four additional ~330cc injectors. Combined with your stock 280cc injectors, you'll have more fuel than you'll need.

    An extra injector per runner means that you'll get an even distribution of fuel among all cylinders, rather than the pre-throttle body injector setups which may cause certain cylinders to run richer and others to run leaner.

    For an additional $250, you can upgrade to a brand new single runner 626 intake manfiold for better airflow and more power.

    (Stock injectors, fuel rail, and hoses not included) Learn More
