Don't be fooled by one of our competitors who offer this pump as one of their own brand name products. It's simply an off the shelf high quality water pump by the company Gates, who we use for many of our other gaskets and engine components (belts mostly). The most important thing about this pump is that it is a brand new core, not remanufactured like a local auto parts store would carry, and it has a cast one piece impeller, not a stamped or multiple piece impeller which can prematurely fail (even the Mazda OEM water pumps are not as good as these).
We use these water pumps on our cars here at 5X Racing and recommend them to you. Gates is a top-quality OEM replacement brand and we have put them to the test on both the street and racetrack.
