Intake Manifold

High-Flow Engine Intake Manifold Assembly
Airflow Optimization & Combustion Efficiency

Precision OEM & Performance Intake Manifolds

Maximize engine horsepower, low-end torque, and airflow distribution across all cylinders with our OEM direct-fit and performance intake manifolds.

The intake manifold evenly channels clean air (or air-fuel mixture) into each cylinder head intake port. Common issues like cracked composite runners, warped aluminum flanges, stuck swirl flaps, or vacuum leaks can cause lean misfires and poor acceleration. Our replacement intake manifolds feature reinforced high-temp nylon composite or cast aluminum construction, pre-installed runner gaskets, and integrated sensor mounts for reliable, leak-free engine breathability.

Symptoms include erratic high idling, engine misfires (P0300, P0171 lean codes), whistling or huffing vacuum leak noises from the engine bay, coolant leaks near the intake gasket crossover, and reduced fuel economy.

Yes! Most of our replacement intake manifold units come with molded silicon intake runner gaskets, throttle body seal rings, and mounting hardware pre-packaged for quick installation.

Composite plastic manifolds endure constant thermal heat soak from the engine block combined with oil vapor and vibration. Over years of driving, the plastic turns brittle and cracks near coolant passages or mounting bolt holes.

Yes, for many engines, aftermarket cast aluminum intake manifolds are available. They eliminate plastic cracking permanently and handle higher boost levels in modified vehicles.

Yes. Cleaning carbon deposits off cylinder head intake ports and scraping old gasket residue ensures a smooth mating surface and prevents vacuum leaks on the new gasket.
