TTE Thermal Shield for BMW S55 hot side, add-on insulation for TTE740 Plus units, part number TTE10386.66

Control underbonnet heat on your F8x M car with this dedicated thermal barrier for the S55B30 twin turbo engine. Designed by TheTurboEngineers specifically for use with TTE740 Plus hybrid turbochargers, this precision-made insulation shield keeps radiant heat in check, helps curb heat soak and safeguards surrounding components for stable performance on the road and at the circuit.

At MJ Modifications we have installed this heat shielding on multiple F87 M2C, F80 M3 and F82 F83 M4 builds and the feedback has been excellent. Lower bay temperatures, improved thermal stability and protection for hoses, looms and adjacent hardware. Daily drivers and track-day customers alike have been very happy with the durability and effectiveness.
