BMR Throttle Body Water Bypass Kit (TB002) - 1998-2002 GM LS1 F-Body
Unlock hidden horsepower in your 1998-2002 GM F-body with the BMR Suspension Throttle Body Water Bypass Kit. Factory LS1 engines circulate hot engine coolant through the throttle body to prevent potential throttle blade icing in extreme sub-freezing climates. For enthusiasts in warmer regions or those building performance-focused engines, this heat soak is unnecessary and negatively impacts intake air temperatures.
BMR’s bypass kit allows you to effectively reroute the coolant lines, keeping the throttle body significantly cooler and allowing for a denser, colder air charge entering the engine. Designed for street performance, drag racing, and handling applications, this kit includes a high-quality billet aluminum adapter, durable hose clamps, and rubber dust caps for a professional finish. Installation takes approximately 1 to 2 hours, making this one of the most cost-effective modifications to reduce heat soak and improve engine efficiency.
