JBR Thermal Insulating Gasket Intake Manifold Mazdaspeed 3 2007-2013 | Mazdaspeed 6 2006-2007

Fitment is great. Looks a lot more sealed then the stock one!! I Recommend this product

Has a pretty good thickness and doing great so far. Have noticed a little difference in temps and enjoy its reusable.

Skeptical at first but worth the price!

I did notice lower temps according the Cobb AP. I haven't reviewed the data logs yet though. Certainly worth installing if you are planning to remove your intake system.

According to the datalog, this seems to have dropped intake temperatures and BATs pretty consistently by about 5 degrees once at operating temperature. I think these shine the most at red lights, where intake temperatures seem to rise the most. Looking forward to see if this helps in the summer.

Who knows what it's doing, but it was affordable and I wasn't going to buy an OEM when I can reuse this fine gasket!

Great quality, even comes with a spacer for the bottom mounting point.

This is a JBR product so as always works as expected and installs perfectly.

Couldnt be more satisfied. It fits and works perfectly. Thanks for the fast shipping too!

Great product and install directions. Continued great service
