B58 Gen2 Intake Manifold

RK Autowerks B58 RK Billet Port Injection Manifold – GEN1

This manifold is designed for plug-and-play fitment using OEM mounting points. Please note that if you are not using port injection, you will need to purchase blanks. Precision Raceworks sells the blanks very cheap. 

RK Autowerks is known for their no-compromise engineering, and this manifold is a direct result of meticulous design refinement, race-tested development, and a commitment to quality. Features include optimized internal geometry and increased structural integrity, ensuring consistent performance across the rev range.

Each manifold includes an integrated billet aluminum fuel rail, precision-machined to support aftermarket injectors and ensure balanced fuel distribution across all six cylinders. It’s built to pair seamlessly with your preferred port injection kit and tuning solution. Fuel injectors and port injection kit are not included.

Whether you're chasing horsepower records or building a reliable, track-capable B58 Gen 1, this manifold delivers the engineering excellence and performance that RK Autowerks is trusted for. Perfect for high-boost, methanol, or ethanol-fueled applications where OEM plastic manifolds simply won’t hold up.
