Customer Reviews: Miata Header Heatshield Blanket--New UPDATED VERSION 1990-2005
After installing a K&N intake, the air intake temperature seemed too high at 160ÃÂ°F (Texas summer, highway speed, 4000 rpm). My first step was to wrap DEI-050503 heat shield around the K&N intake tube. That reduced the heat soak due to hot air from the radiator. Next I installed the heat-shield blanket (very easy on a '99 Miata). These modifications reduced the intake temperature by at least 10ÃÂ°F. After six weeks of summer driving, the average temperature reduction has been about 20ÃÂ°F. In the past it took 15 minutes for under-hood temperatures to rise, now it takes an hour.
Once again, Good-Win comes through with delivery of my order in less than 24 hours. Love that!
This heat shield is a perfect fit for my Miata with a 99-00 JDM block. It took me all of about 15 minutes to install. I must admit I'm not a mechanic by an means, but this was easy-peasy. Two sockets and a torque wrench.
I have an aftermarket intake which crosses over to the hot side, so I grabbed this item to control the intake temps. I felt different parts of the intake after a full session on track, and it was warm but certainly not hot. I feel like that is as good as I could hope for.
Lightning fast shipping, great product, easy install ... happy camper!
I installed this blanket on a GWR header. The material seems to be very good quality. Installation was straight forward, the fit was very good. I used it during a weekend of racing at WSIR. The under hood temp was definitely lower and after a 20 minute session I was able to touch the blanket with my hands.
I bought a 99 California car with the exhaust heat shield missing. The manifold with the second catalytic converter attached got so hot I could hardly pull the dipstick. The updated heat shield blanket fits great, stays cool and looks cool!
Since installing header several years ago, the under hood temp. was a bit much. Installed Fast Forward blower kit a few months ago. Getting lazy and looking for an easy way to lower under hood temp bought this blanket. It has dramatically reduced the temp and installed in about 10 min. Price was the best I could find. Thanks.
