Volvo 740 & 940 Airbox Thermostat Delete Tube

Replace the failure-prone factory airbox thermostat system with a simple, permanent solution that routes fresh air directly from the front of the vehicle. This eliminates the common failure mode where the thermostat remains open and causes the engine to draw warm engine bay air.
