Opel Z16LER Billet Intake Manifold
Description
The factory OEM plastic intake manifold suffers from poor airflow geometry, creating a highly dangerous restriction that leads to the notorious 4th cylinder lean problem, which frequently causes engine failure under load. Our innovative side-feed plenum engineering completely fixes this flaw, ensuring a flawless 100% equal airflow distribution and uniform mixture to every single intake port. This perfect balance guarantees safe, optimized power delivery across the entire powerband, keeping your engine protected even under extreme racing loads.
To support your upgraded high-horsepower fueling demands, this manifold comes complete with a custom-matched, high-flow billet fuel rail designed for your primary injectors. To completely remove intake restrictions and ingest massive air volume, the manifold accommodates multiple throttle configurations, offering dedicated flange choices that support an upgraded high-flow 70mm or massive 75mm throttle body setup.
- Side-Feed Plenum Design: Optimized high-capacity side-entry plenum configuration engineered for fast throttle response, uniform air distribution, and absolute structural strength under immense boost pressure.
- Velocity Stack Design: Individual runners featuring high-flow venturi effect velocity stacks for superior cylinder filling and maximized airflow velocity.
- Auxiliary Injection Ready: Built-in provisioning with dedicated water-methanol or nitrous injection ports (1 dedicated port per cylinder) to safely support your cooling and octane requirements under extreme load.
