M177 Auxiliary Performance Radiator

Lower intake and engine temps with these auxiliar radiators. There are 2 of these on a number of M177 vehicles, one for the intercoolers and one for the engine. Keep your engine and intake temps happy with these oversized cooling radiators. Quick Highlights:1. Stock system has very poor heat soak characteristics. Intake Air Temps (IATs) rise about 15% per 60-130mph run in 90°F ambient conditions, resulting in major power loss after a few pulls. 2. Our Stage 1 system reduces IATs by 45% and 25°F after 5 successive pulls. One of the biggest benefits is reduced heat soak capacity and the ability to keep putting down more power. We achieve this through a proprietary core design and changing the system from a single pass to a triple pass coolant path. 3. Stage 1.5 further enhances Stage 1 with the additional auxiliary cooler which provides 54% and 30°F peak IAT reduction at the 5th run. 4. Our Aux cooler can double as an engine cooler and shows up to 12°F cooler engine coolant temperature
