Pay the extra and get these manifolds. Strength, fit and machining are all top notch. They’ve been on for a month or two with no issues. Even with the poor packing that CarParts did they survived shipping without damage and bolted up without issues.

Great manifold. Well machined flange and very flat when checked with a straight edge. Screw in plug to protect the oxygen sensor bung and the ball flange for the cat is well machined as well. Packaging sucked! That last part cost CarParts a 5 star. Best price I could find.

This was the perfect fit and it arrived very quickly! I can’t even imagine a company that promises 5 day ground shipping and it arrives in 2 days. Highly recommend!
