To effectively address the inadequate factory heat shield on the M340i, which allows excessive turbo heat to compromise performance, we engineered a superior solution.
The HPS Cerakoted Steel Turbo Heat Shield is constructed from heavy-duty steel for robust durability and is treated with a Cerakote ceramic coating. This advanced coating significantly improves heat rejection characteristics, ensuring the shield itself doesn't cause heat-soak.
The most critical upgrade is the shield's superior coverage. Our streamlined, one-piece bolt-on unit provides more than double the surface area compared to the factory shield 144.29 sq. in. vs. 67.77 sq. in. By blocking significantly more radiant turbo heat, the shield's core function is to maintain cooler Intake Air Temperatures (IATs). Cooler IATs prevent the ECU from automatically reducing boost, ensuring the engine can consistently operate at its peak performance level, especially during spirited driving.
The unit is a straightforward direct bolt-on replacement and includes all necessary stainless steel hardware. The combination of robust Cerakoted steel, enhanced thermal performance, and a clean aesthetic makes this heat shield an essential upgrade for maintaining optimal B58 power and engine efficiency.
