BMW Radiators for BMW 3 Series E30 (1984-1991)

Clear BMW chassis

Please ensure your correct model is selected

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.

Give your vehicle a cooler, more efficient running engine by installing a performance Mishimoto aluminum radiator. These radiators are a direct replacement to the factory unit making it an effortless install and provides up to a 30% more cooling capacity. Made from aircraft quality aluminum, these radiators have a dual row core and polished end tanks. So what are the advantages of an aluminum radiator? Well, first is the lightweight aspect of the radiator. You can run a larger radiator at the same weight as a stock unit. Also, in case of leaks years down the road, an aluminum radiator can be welded and repaired, saving costly replacement in the future. It is also much more durable, channeling heat better and resisting cracking and breaking, even at high temperatures. WARNING! Prop 65 may apply to this product.

Mishimoto X-Line E36 Aluminum Radiator features - 90% more capacity with thicker core 30 degree reduction in coolant temp All aluminum construction Hanger tabs for Euro oil cooler included More durable and longer lasting than plastic components Excellent fit and finish Unbeatable lifetime warranty and accident-forgiveness Mishimoto radiators address all of the defects of the stock E36 radiator in a well-engineered and price-competitive direct replacement unit. The Mishimoto X-Line radiator is an all aluminum design that replaces the factory plastic and aluminum stock radiator. The stock plastic end tanks are notorious for cracking and leaks whereas the Mishimoto has aluminum end tanks that will never fail. The X-Line uses a thicker core than stock for 91% more coolant capacity but still fits in the original location with no modifications. More coolant volume means the fluid is not heat soaked for as long (less super heated 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 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.
