Using Banks’ Ram-Air cooling technology, this pan dissipates more heat than factory or competitor pans. Features include a break-away Ram-Air scoop, an additional 2 quarts of capacity, and Banks FlowThru Fins to help cool the fluid for longer-lasting transmission performance.\u003c\/p\u003e\n\u003ch3\u003eEngineered to Run Cool\u003c\/h3\u003e\n\u003cp\u003eThe forward-facing scoop channels ambient air through external FlowThru Fins for maximum heat transfer. The pan includes 2 extra quarts of fluid capacity. The plastic scoop is designed to break away without damaging the pan, and Banks will replace it free of charge if needed. Optional Deep Pan adds ~3 quarts of fluid capacity for enhanced cooling.\u003c\/p\u003e\n\u003ch3\u003eBanks vs Competition\u003c\/h3\u003e\n\u003cp\u003eDie-cast construction ensures smooth, low-porosity surfaces for optimal fluid flow.
