🔧 Dorman 615-178 Intake Manifold for Ford, Lincoln, Mercury - Engine Component Selection Review

It has been a few years since I purchased and installed this manifold so this is the 'confirmed' rating we all look for when we read reviews.

I first noticed a small coolant leak due to a crack in the thermostat "cup" (also originally plastic). The improved manifold with aluminum transition pipe perfectly matched the original. As…

This fixed a leak in the thermostat housing on a 4.6 liter Ford engine on my Lincoln. This is a common problem with these engines and was the most economical solution.

I believe Dorman either sold the instruments or the rights to their design. So if you see a cheaper version of this air intake, look at the pictures and the part number and think "Yes, it's exactly the same but with a different name painted on the front", you know it's not is the case.A unit I bought…
