E9X 335, E82 135 6MT Mishimoto Performance Aluminum Radiator - Automatic

Product Details

As most 335 owners have discovered, the cooling system is vital to maintaining high levels of boost. The car's sophisticated electronics wisely shut down and limit boost when temperatures are elevated enough to do potential harm. Don't short-change your cooling system or performance on the street or the track! Where the stock radiator suffers is in capacity, which is why BMW also sells an additional radiator and other cooling upgrades with their Performance packages. This radiator for the E90/E92 335 and E82 135/1M is a larger 40mm core (2mm thicker than stock) for additional capacity and bulletproof cooling. It fits in the stock location, with the stock shroud and fan (some plastic trimming may be necessary), maximizing the available space to dedicate to fluid capacity and surface area. Having a greater capacity means less saturation time for the cooling fluid which leads to more consistent engine temperatures, reducing the possibility of limp mode condition and reducing wear and tear on other cooling components such as the water pump and thermostat. If you're looking for the most complete and unbeatable radiator solution for your E9X, this is the best we have seen. 

Not only is this radiator larger, but it's also designed with the stresses of motorsports in mind. The cooling vanes use a unique oven-brazed bonding technology that will not fatigue and crack like epoxyed construction. Aircraft-grade aluminum is used for the tanks and frame, which are TIG-welded for superior strength. This radiator is a direct replacement for the stock E9X radiator, with all of the same hose locations and fittings as the original radiator. Because of the extra depth required between the radiator and engine, extra care will be needed when installed with upgraded intercoolers, intake piping, and oil coolers. 

This aluminum radiator is a replacement for the stock BMW radiator 17 11 7 558 480 and fits the 135i and 335i/xi (automatic transmission only).
