Part Details

  • Location: Lower

Our intake manifolds are some of the highest quality replacements on the market!

This cast ALL aluminum lower intake manifold with installation kit for GM trucks with the 5.0L & 5.7L is a new, aftermarket replacement part. It is a direct bolt on that is built to strict quality control standards.

The original intake manifold, due to the design, has an abnormal tendency to crack or warp, leading to overheating and in many cases complete engine failure and/or damage to other parts of the truck's engine. This new and improved lower intake manifold is designed to eliminate those problems!

Specifications:

  • Made from cast aluminum
  • Highly engineered
  • Fits only 5.0L 305ci and 5.7L 350ci V8 engines

Installation kit includes the following which is pictured below:

  • Coolant Nipple
  • Distributor Cap Screws
  • EGR Gasket
  • Fuel Injector O-Ring Set
  • Fuel Line O-Rings
  • Fuel Meter O-Ring
  • Lower Intake Manifold Gaskets
