fitment, cleanliness, and ease of installation were superior. It was as if the old one was pulled off and put right back in. Further, it is such a treat to receive a part that was thoroughly clean and not covered in sticky preservative or anything of the like. in closing, customer service people were wonderful to deal with.

Best price around, smooth, quiet and Cali legal. Got here in 2 days. Everything needed to install is included. Truck has 421k, really runs good, new injectors from Riffraff last year.
