Review on ATP Automotive Graywerks 101403 Manifold by Gerardo Cibrian

Revainrating 4 out of 5

Great for GMC Envoy 4.2L

Worked great for my 2002 GMC Envoy with Vortec 4200 engine. Only thing the store said was that some screws were missing. Update: After about a year/20,000 miles the car is making the same ticking noise as before when the original manifold was leaking. Not sure if it's the manifold this time as it has about 230,000 miles on it and the engine is still noisy, but if it's the manifold I'm a bit disappointed that it's already failed when the original lot lasted longer.

Pros
  • Manifold
Cons
  • Some trouble
