The Mazda 2.3L MZR DISI engine is assembled using paper thin metal gaskets between the intake manifold and cylinder head. The same paper thin style metal gasket is used between the throttle body and intake manifold. This design allows intense heat to be transferred to both, greatly increasing boost air temperature and robbing you of horsepower.
The JBR Thermal Insulating Throttle Body Gasket & Coolant Bypass Kit prevents this unwanted transfer of heat from the intake manifold and eliminates the 200°F coolant from flowing through it. This reduces boost air temps and increases horsepower.
Constructed out of .062 virgin grade PTFE with a temperature rating of 500°F. CAD designed and ported to ensure there’s no reduction in flow and it’s reusable too!
The JBR Thermal Insulating Throttle Body Gasket Kit is stackable up to 4 thick while utilizing stock mounting hardware.
Application: Mazdaspeed 3, All
Kit Includes:
1 Insulating Throttle Body Gasket

2 Coolant inlet caps

The JBR Thermal Insulating Throttle Body Gasket & Coolant Bypass Kit performs even better when combined with the JBR EGR Block off Kit. What’s the point in re-circulating hot exhaust gas in to a cool intake plenum?

Simple install lower Temps
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, throttle body included.
