BMW Radiators

We sell only OE supplier or approved aftermarket upgrade radiators for your BMW. It seems BMW took some shortcuts when it came to radiator design and used weak materials like plastic for critical connection points. If you are tracking older models like E30, E36, or E46, you probably are well aware of these issues. As these cars age, the plastic pieces become more brittle and failure prone. The solution is to replace with upgraded radiators that perform as upgrades for the original, failure prone radiator to avoid being left on the side of the road or, worse yet, the track.

This heat exchanger upgrade is a high-quality replacement that dramatically lowers engine oil and water temperatures by providing a 50% larger cooling surface than OEM. The benefits are most noticed during back to back runs at higher boost levels where the factory cooling capacity can be overwhelmed resulting in ignition timing pull and reduced turbo efficiency. Direct bolt-in installation.

Dramatically increase the cooling performance of your Supra with Mishimoto's new Performance Aluminum Radiator. Key Features: All aluminum construction More durable and longer-lasting than plastic components 30% more capacity in the same space 180% Increase to external fin surface area Excellent fit and finish Unbeatable lifetime warranty and accident-forgiveness Mishimoto radiators address all of the defects and deficiencies of the stock Supra auxiliary radiators in a well-engineered and price-competitive direct replacement pair. Mishimoto's radiators feature an all-aluminum design that replaces the factory plastic and aluminum stock radiators. BMW style plastic end tanks are notorious for cracking and leaks, whereas the Mishimoto has aluminum end tanks that will never fail. Mishimoto also allows a 30% increase in coolant capacity into the radiator that fits in the original location with no modifications. More coolant volume means the fluid is not heat soaked for as long (less superheated fluid circulating through the engine). For a direct replacement performance radiator, the Mishimoto is hard to beat! Mishimoto was established in 2003 as a supplier of cooling components for drift and rally cars. Their radiators and intercoolers soon found a strong following in the hyper-competitive drift scene where high horsepower and prolonged high revs dictate the need for durable and robust cooling solutions. The catchy Mishimoto name is a combination of the name of the founder's family pet - Mishi - and "moto". All products are designed and tested in the USA using state-of-the-art CAD tools and prototyping and with the continuous evolution of product design. Mishimoto is so dedicated to quality that they offer a limited lifetime warranty and accident forgiveness. WARNING! Prop 65 may apply to this product. Proposition 65 (Safe Drinking Water and Toxic Enforcement Act of 1968) is a California law that applies to call companies selling products in California.

This performance heat exchanger from CTS features a number of upgrades over the stock intercooler, offering better reliability and cooling performance. The first major upgrade is the heat exchanger's full alumnimum constructions. The factory heat exchange is partially constructed from plastic, which is prone to damage and cracks as the plastic becomes brittle over time. Full aluminum construction results in a stronger intercooler, which will last the lifetime of your BMW. The second major upgrade is a redesign of the coolant flow path and fin layout. This redesign allows for higher cooling efficiency, resulting in greater heat dissipation and reduced coolant temperatures.

The 3.0L I6 bi-turbo engine of BMW M3/M4 models is equipped with an indirect charge-air cooling circuit. So the cooling of the charged air is not realized by the ambient air as cooling medium (as usual), but made with its own cooling water circuit. A reduction of the temperature of the cooling water is directly equated with an improved cooling performance of the charged air. This is exactly where the advantages of the WAGNERTUNING upgrade water cooler comes into play. The new developed competition racing core of the WAGNERTUNING high-performance water coolers increases the radiator volume of the OEM water coolers by a total of 60 %. The calculated ratio between the inner and outer cooling surface generates a maximum heat transfer and allows at the same time enough air flow for the surrounding components (for example the engine water cooler) for its own heat exchange. The water coolers are equipped with a heat-conductive anti-corrosion coating to ensure a lasting cooling effect. The plug & play installation of the system is simple and easy to perform (an installation instruction is included as well). Dimensions OEM radiator: 505 mm x 605 mm x 30 mm V = 9.16 Liter A = 3055 cm² Wagner Dimensions 505 mm x 605 mm x 48 mm V = 14.67 Liter A = 3055 cm²
