Outstanding product design. Paired with a Hayden 678 cooler and magnefine filter. Was able to complete installation without removing the bumper. Cooler gets great air flow. Pinning the transmission thermostat open and performing a fluid drain and fill flushed the radiator and external cooler. Trans thermostat doesn't open until around 180 deg so pinning it open allowed fluid to flow through radiator cooler and they Hayden external cooler and dropped my transmission temps (during winter months around 25-50 deg ambient temp) from 185-190 without cooler to an impressive 145 degrees around town. This should show significant drops in summer time. Overall very satisfied with the craftsmanship of this product and have made recommendations on this product to the reddit community. Thank you!
