Its aim is to achieve more stable temperatures (coolant\/oil – depending on vehicle configuration) under high load, such as during sporty driving, track days, or with performance-enhanced setups. Designed for high flow rates, the thermostat promotes more even heat dissipation and can reduce heat spikes in demanding operating conditions.\u003c\/p\u003e\n\n\u003c\/section\u003e\n\u003csection\u003e\n\u003ch2\u003e Performance features\u003c\/h2\u003e\n\n\u003cdiv class=\"kth-card\"\u003e\n\n\u003cul class=\"kth-list\"\u003e\n\n\u003cli\u003e Performance-oriented thermostat for M156 \u0026amp; M159\u003c\/li\u003e\n\n\u003cli\u003e Supports more stable operating temperatures under high load\u003c\/li\u003e\n\n\u003cli\u003e Optimized for sporty use and high-performance vehicles\u003c\/li\u003e\n\n\u003cli\u003e Focus on flow rate and reproducible temperature behavior\u003c\/li\u003e\n\n\u003cli\u003e A useful addition to upgrades such as downpipes, supercharger\/charger setups, mapping (depending on the vehicle)\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\n\u003c\/div\u003e\n\n\u003c\/section\u003e\n\u003csection\u003e\n\u003cp\u003e\u003c\/p\u003e\n\n\u003ch2\u003eScope of delivery\u003c\/h2\u003e\n\n\u003cdiv class=\"kth-card\"\u003e\n\n\u003cul class=\"kth-list\"\u003e\n\n\u003cli\u003e BlackBoost Wide Open Thermostat (vehicle-specific version)\u003c\/li\u003e\n\n\u003cli\u003e Note: Seals\/additional mounting material depending on kit\/variant\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\n\u003c\/div\u003e\n\n\u003c\/section\u003e\n\u003csection\u003e\n\u003cp\u003e\u003c\/p\u003e\n\n \u003ch2\u003eTechnical details\u003c\/h2\u003e\n\n\u003cdiv class=\"kth-card\"\u003e\n\n\u003cul class=\"kth-list\"\u003e\n\n\u003cli\u003e Application: Mercedes-AMG engines \u003cstrong\u003eM156\u003c\/strong\u003e \u0026amp; \u003cstrong\u003eM159\u003c\/strong\u003e\n\n\u003c\/li\u003e\n\n\u003cli\u003e Function: Optimization of thermal management (flow rate \/ temperature stability)\u003c\/li\u003e\n\n\u003cli\u003e Recommendation: Professional installation, system bleeding and coolant level check\u003c\/li\u003e\n\n\u003cli\u003e Note: Results depend on vehicle, peripherals, and setup.\u003c\/li\u003e\n\n\n\u003c\/ul\u003e\n\n\n\u003c\/div\u003e\n\n\u003c\/section\u003e\n\u003csection\u003e\n\u003cp\u003e FAQ\u003c\/p\u003e\n\n\u003csection open=\"\"\u003e\n\u003csection\u003e\n\u003ch3\u003e Does the thermostat improve temperature stability?\u003c\/h3\u003e\n\n\u003c\/section\u003e\n\u003cp\u003e It is designed to support more stable temperature behavior under high load.
