Thank you. You have rated this product.

Heat exchanger upgrade for the 2006-2015 MX5 MP62 Supercharger kits. This is the same heat exchanger used on our 300+ HP silver car.

Width and height of this cooler are nearly the same as the cooler that comes included in the MP62 kits, but core thickness goes up 25% and more efficient core design so it can shed much MORE heat and capacity about doubles thanks to big chunky end tanks (more water means system slower to heat and much more stable temps on long pulls down big Nascar straights like Fontana). Make sure your supercharged MX5 can take on any weather and any conditions you can throw at it! Perfect upgrade for supercharged cars that see track use.

INCLUDES new lightweight precision-made aluminum brackets to fit this cooler in the same position as the one it replaces. These brackets have a modular design so you can add our 19-row oil cooler kit later if you wish - that means you don't have to decide between a bigger cooler for the supercharger OR an oil cooler!
INCLUDES corrosion-resistant metric grade 10.9 hardware.

No changes to the tune are necessary, just bolt on and go.

After reading many other positive reviews on both the GWR and Miata forums I finally decided to buy this product. My main concern for many months was whether or not I was up to the task of installing the header. But with the excellent instructions on Brian's forum as well as several Miata forum threads it turned out easier than I expected. After receiving notice that the header would arrive on a Friday afternoon, I began the disassembly process. After about 3 hours I had the stock manifold out. Later that afternoon the new catted header arrived right on schedule. And it is a thing of beauty. I opted for the stainless version. Installation on Saturday morning took another 3 hours, although I could have shaved some time off of that but I was actually enjoying the process of double checking torque values and cleaning up my engine compartment. I already have the GWR catted midpipe, so that connection was a snap. I put everything back together, reconnected my battery, and went for a drive. NO CODES! Nice throaty sound with my RSII muffler, and a significant boost in power and low/mid torque. Another happy camper here. I since have added a M-E tune and I feel I have realized all of the gains that Brian has achieved on his 2012 project Miata. I've put several hundred miles on my Miata since the install with zero problems. This is the car that Mazda should have built all along. Thanks Brian.
