Customer Reviews
Very high quality built. I was able to take the heat sleeve off with ease so I could have it ceramic coated. I reached out to Dmaxstore for their opinions on brand and they reached right back out with the answer. Install was a pain having to lift the cab. I would recommend purchasing AC Delco #29536834 for the transmission dipstick. When I pulled my dipstick, this rubber seal was very hard and brittle. Had to wait an extra 2 days for a new one to come in the mail. I think Dmaxstore should have this as an option when purchasing. Otherwise it seems to have helped in airflow and a very minor bump in MPG
great fit. good quality. smoother air flow. recommend buying a new trans dipstick seal when doing this project.
Easy installation. Make the truck feel slightly more responsive.
Excellent product! I haven’t fully tested it yet but the truck sounds better.
Fit perfect 🤙🏽
