We love feedback! And this is one killer review/opinion from a couple of guys who were helping us develop our Instant Muscle Shield for the 2011-2014 V6 Mustang. Here the test comments.

"I was able to meet up with my son (FoolnYa) this afternoon and do a comparison test between our cars and the 'Heatshield Products Intake Cooler' Reflector. My son's car is a 2012 3.7 M6 with 3.73 gears, mine is exactly the same except for it is a 2011.

Our cars both have BBK chrome long tube headers with O/R X-pipes, JLT plastic tube CAI's (mine is painted, his is plain). I have the BBK 73MM TB and Lone Wolf ported manifolds, he has a self ported stock TB and stock manifolds. My car has the Heatshield Products Cooler/Reflector, his does not.

Both of our cars had been sitting overnight. We started the cars and drove about 5 miles of normal driving to get the cars up to full operating temperature. The outside air temperature was 84 degrees. We then pulled into a parking lot and opened the hoods and took 3 different readings. One reading was right above where the vacuum line from the brake booster plugs into the upper intake. The second reading was right behind where the strut tower brace crosses the manifold. The third reading was right near the rear of the manifold.

The second test we started the cars back up and drove about 5 miles at 60 MPH on the freeway and then turned unto a side road and did one WOT blast from 1st gear through the top of 3rd gear and pulled into a parking lot and took the same readings as the first time.

We both had heat guns so we both took readings and then I took the average of the two. Most of the readings the guns read within one degree of each other, the largest difference was 6 degrees. We tried to take the readings with the guns at the same angles to make the results as accurate as possible.

Here are the results:

Cold start, 5 miles of normal driving, cars at normal operating temperature:


With Heatshield Products Cooler/Reflector readings from front of the intake to the back were 99 degrees, 99 degrees, 100 degrees.
Without Heatshield Products Cooler/Reflector readings from front of the intake to the back were 138 degrees, 138 degrees, 137 degrees.

The cooler/reflector intake was 37-39 degrees cooler than the other intake.

5 miles of 60 MPH cruising, then WOT blast from 1st through 3rd gears With Heatshield Products Cooler/Reflector readings from front of the intake to the back were 114 degrees, 115 degrees, 115 degrees. Without Heatshield Products Cooler/Reflector readings from front of the intake to the back were 129 degrees, 131 degrees, 132 degrees. The cooler/reflector intake was 15-17 degrees cooler than the other intake. he results were pretty interesting and

I definitely think that this is a worthwhile mod for our cars, especially since it is inexpensive and pretty easy to install!! "
