Maradyne Champion Series Electric Fans
Maradyne Champion series electric fans are great for use on remote transmission coolers, oil coolers, or intercoolers. They feature a reversible motor, so they can be used as a puller or pusher type, depending on your space constraints. They use sealed motors, perfect for harsh conditions, including off-road, and they can be sprayed clean without moisture entering the motor. The Maradyne Champion series electric fans have a glass-filled nylon shroud and blade and are high-temperature and impact-resistance for harsh underhood temperatures and greater resistance to flying road debris.

Mishimoto Thermostats
Mishimoto thermostats are effective in noticeably lowering engine coolant temperatures. These thermostats are built with high-quality wax and are shipped with new rubber gaskets (where applicable) for a good, leak-free seal. They are then digitally calibrated for precise operation. Mishimoto thermostats open up at a slightly lower temperature than OEM or standard thermostats once your engine is fully warmed up. This allows the coolant to flow through the engine sooner, thus reducing and maintaining cooler engine temperatures. Whether you have a daily driver or a modified and upgraded turbo, Mishimoto thermostats will maintain optimal temperatures to efficiently cool your application.

Denso Air Conditioning Accumulators and Receiver-Driers
Often overlooked, accumulators and receiver-driers play an important role in A/C operation. Denso air conditioning accumulators and receiver-driers manage the flow of liquid and vapor refrigerant through the system, assuring maximum output and smooth, surge-free operation. They also contain powerful desiccant packages to isolate harmful moisture from the system. This protects the internal components from corrosion that can wear systems prematurely from the inside out and create costly leaks. When major A/C service is performed, replacement of the accumulator or receiver-drier is often recommended. Denso accumulators and receiver-driers are manufactured to the most stringent OE standards to provide new-car performance and efficiency. Additional features of Denso air conditioning accumulators and receiver-driers include: * Denso First Time Fit provides the right part and the right fit ... the first time, every time * Close tolerance manufacturing ensures durability * Solid construction supports the higher operating pressures of newer systems * Helps to remove debris and moisture from the system * Assures cold A/C temperatures, on even the hottest days * Promotes smoother, quieter A/C system operation
