Review on Premium Upper Intake Manifold with Gaskets for Ford F250 F350 E150 E250 E350 E450 5.4L V8 - MOSTPLUS 615-188 by Jeff Ross

Cheap collectors with poor quality control. Received an elbow with a leaking adapter pipe and cross thread bolts (1st two pics). I fixed and installed it as best I could, didn't have time to wait for another one or I would have sent it back. The collector had been in service for a little over a month when the rear seal (3rd photo) for the pipe failed and antifreeze leaked out. Contacted the manufacturer for a replacement as Amazon's return policy has expired and it says it has a 1 year warranty. Good luck if they honor it. They still haven't even replied to my email and it's been over a week now. Buyers beware of poor quality control, slow customer service. I will never buy Mostplus products again.
