Thank you. You have rated this product.

The TDR Heat Shield was designed to help keep your under hood temperatures in check. It is manufactured using heavy-grade industrial aluminum to reflect radiant heat and to balance the conducted heat across its surface. Insulation is 2000 degree rated ceramic wool that helps maintain its shape as you form the TDR Heat Shield around the exhaust manifold or header. The outer surface is an aluminized fiberglass mat that not only looks good, but also adds to the efficiency by dissipating heat, resulting in lower surface temperatures.

Why the Heat Shield is a better option over header wrap: Cool air needs to be around the header, and insulating it with a wrap to hold exhaust heat in makes the header material surface temperatures reach near molten levels. When you wrap the header you trap the heat in the header, but also suffocate the material that needs to breathe to dissipate heat for its own survival. Most header manufacturers will NOT WARRANTY a header which has had a wrap installed on it. We also know that headers have been destroyed after running headers wraps, and these headers were on perfectly tuned engines. If you want a true thermal barrier that will reduce under hood temperatures without damaging your header or voiding its warranty, the TDR Insulated Heat Shield is the obvious choice instead of header wrap.

Works with factory manifolds and all aftermarket headers for all Miatas and MX-5s and is a must for supercharger applications. Creative customers have also used these insulated heat shields on everything from Honda Civics to V8 powered race cars.

Updated in 2013, this heat shield was improved with an additional layer of fiberglass mat and increased in size by about 20% so it works better with the Racing Beat header and the NC cars. Now 1 " wider and 3" longer in size.

Shown below on NA/NB Generation Miata but install looks about the same on the NC generation MX5 Miata.

REVIEWS

As you can see, i placed another order for more parts for my car. I wanted you to know that I'm pleased at how quickly the wheels/tires came, and the radiator too. Great service and response time.

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.
