Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
Intake Manifold
The intake manifold is a 2-piece (upper and lower) aluminum casting. Runner lengths are tuned to optimize engine torque and power output. Manifold provides mounting flanges for throttle body assembly, fuel supply manifold, accelerator control brackets, EGR valve and supply tube.
Vacuum taps are provided to support various engine accessories. Pockets for injectors are machined to prevent air and fuel leakage. Pockets in which injectors are mounted are placed to direct injector fuel spray immediately in front of each intake valve.
