This electric fan for the E46 M3 takes the place of the stock engine-mounted fan and offers several advantages - more horsepower by removing parasitic drag customizable temp control (with optional fan controller - not included in this kit) frame included for a direct fit more reliable than a stock-style fan clutch The stock engine fan is mounted on the water pump shaft and spins with the engine. Torque from the engine is used to spin the fan, which could otherwise be used to power the car. It's not a lot of lost power and torque - Mishimoto measured a max gain of 5whp - but sometimes every little bit helps. And the other advantages of an electric fan make it a smart move. The Mishimoto electric fan uses a 16" slim profile electric fan that flows at 1,850 cubic feet per minute (CFM). The shroud and frame are black powedercoated steel and mounts to existing points on the radiator for a seamless install. Mishimoto has confirmed fitment with stock radiators as well as their own Performance and X-Line aluminum radiators. Hardware and instructions are included. An electric fan must be powered by a 12v source. A fan controller kit is optional and is activated by coolant temp. This is the preferred setup method but other types of controls may also be used. Looking for a kit that includes the fan controller and temp sensors? See T#637722

Mishimoto radiators address all of the defects of the stock E46 radiator in a well-engineered and price-competitive direct replacement unit. The Mishimoto 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. Mishimoto can also build 30% more coolant capacity into the a radiator that 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!

Since 2010, Advanced Auto Fabrication has been producing and developing both parts and full fledged race cars. Their knowledge base covers a wide range of vehicles both domestic and imported. In the specific case of BMW, the team at AAF has a particular affinity for building and designing components for BMW race cars. Ideal for the SE46 racing series, the AAF E46 6-speed Transmission Crossmember is a heavy-duty and worthwhile upgrade. The OEM thin cast aluminum cross member has been known to fail in multiple different ways. When using stiff engine and transmission mounts, the cross member can crack out and break around these mounting points. The cross member can also break from the high amounts of load transferred through the drive train. While chassis flex from hard cornering is being applied through the engine and transmission from the front cross member, this load is sent from the transmission back into the chassis at the transmission cross member. This is simply too much stress for the OEM cross member to hold up to under the extreme punishment of road racing. The AAF E46 Transmission Cross Member is completely constructed of 1/4' thick heavy-duty aluminum plate. It is designed specifically to cope with hours of endurance racing.

More than likely, you are going to replace the radiator in your vehicle at least once. The joints where the cores meet the end tanks tend to get weak and are the first place to spring a leak. Impacts to the fins themselves can cause holes to form. Corrosion and clogging from the inside can make cooling less than effective and compromise coolant flow. Replace your leaking unit with a factory replacement and get that jug of coolant out of your back seat. This is a factory original style radiator from Genuine BMW and will fit perfectly into the stock location. Cooling will be identical to what your car came with originally. A great replacement with all the proper connections and in all of the proper locations. When doing radiator and cooling service, you will obviously lose coolant. Browse through the cooling section of your model to see factory correct coolants, seals, and caps. Before beginning, check your hoses to make sure everything is in good shape.

Water Wetter is a unique wetting agent for cooling systems which reduces coolant temperatures by as much as 30*F. This liquid product can be used to provide rust and corrosion protection in plain water for racing engines, which provides much better heat transfer properties than glycol-based antifreeze. Or it can be added to new or used antifreeze to improve the heat transfer of ethylene and propylene glycol systems. Designed for modern aluminum, cast iron, copper, brass, and bronze systems.

We have been using RedLine Oil in our street cars and race cars for years. Hands-down, it is the Number One brand of high performance lubricant for BMWs.
