1995-1997 Buick Riviera Intake Manifold Upper V6 3.8L (excluding Supercharged Models)

This part replaces:

  • DORMAN 615-180
  • OE # 89017272
  • HOLLANDER 329-1438

  • New

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

The original intake manifold, due to plastic construction, fails because of the intense heat of the EGR port. This heat causes the plastic to corrode and will create white exhaust smoke that appears much like a blown head gasket.

Another prone failure of the original intake manifold is along the gasket sealing area. If this area warps, it will cause a vacuum leak or an external coolant leak from the area under throttle body. Both of these will cause poor engine performance.

Specifications:

  • Brand new Upper Intake Manifold
  • Replaces dealer part numbers: 89017272, 89017554, 17103013
