The Mishimoto racing thermostat for 2003–2006 Mercedes‑Benz E55 AMG is a direct-fit replacement for the M113 5.4L supercharged engine that opens at a lower temperature (180°F) than the stock unit to promote earlier coolant flow and more consistent operating temperatures. Intended for street or track AMG use, it helps reduce peak engine temperatures and includes Mishimoto’s Lifetime Warranty for long-term support.
