Automatic transmissions are reliable, shift smoothly, and can last without issue so long as they are properly maintained. Over time, the transmission fluid becomes thick and the filter becomes contaminated with small metal particles. This can cause excess wear, high transmission operating temperatures, and eventual failure. To prevent this we recommend changing your filter, fluid, and seals to ensure your transmission continues to operate flawlessly. We recommend filter and fluid changes every 50,000 miles. Included in this kit are high quality Red Line D4 ATF fluid and OEM filters, seals, and plugs.

The oil in your manual transmission is extremely vital to the life of your transmission. Over time it will begin to break down, lose viscosity, and begin to allow excess heat and friction. This kit is the perfect remedy to this problem. Included are 2 quarts of Redline MTL 75w-80 transmission fluid, which features a fully synthetic base for better protection and wear resistance, and Genuine BMW fill and drain plugs.

Turner's Tip for a healthy S14:
+ Take a peek at your alternator � is the alternator belt riding a little crooked? If it is � replace your alternator bushings with our HD ones (and replace the belt too)
+ I suggest keeping a spare cap and rotor in your tool box. They're hard to get in a pinch and I have seen them go bad out of the blue.
+ A spare fuel pump relay is a good thing to have too.
+ Keep an eye under the water pump for any signs of weeping � usually they give a unnoticed warning when they start to go�
+ For best performance replace spark plugs every 15,000 miles.

    Often an oversight in maintenance, ignition components are also susceptible to wear and tear. Spark Plugs can accumulate carbon, reducing the spark intensity and it's ability to properly ignite the air/fuel mixture, leading to misfires and generally declining performance. Other ignition components, such as coils, boots, wires, caps, and rotors, can also wear out over time due to factors like heat and contamination, preventing the current from reaching the spark plug. To start over fresh with all new components, we now offer these Ignition Service Kits. Each kit comes with brand new high quality components, replacing any potential fault points in your ignition system for peak performance! The kit includes: Bosch Spark Plugs Karlyn Spark Plug Wires Bremi Distributor Cap Genuine BMW Distributor Rotor

    Over time, accessory belts begin to wear out and crack. This can lead to the belt slipping, squeaking, or even snapping. Replace your belts and tensioners on a regular basis to ensure you don't end up stranded on the side of the road with a dead battery or over heated engine due to a bit of simple overlooked maintenance. This kit includes the belts and tensioner bar.

    This cooling package for the E30 M3 consists of all of the major components on the S14's cooling system. There are no major weak points to the E30's cooling system, unless you count skipped maintenance. The entire system is serviceable in individual components so you don't need to buy a complete package of parts. Many of the indivdual parts are on our site but we have setup this package to cover all or most of what you would need to perform a major overhaul. This overhaul package consists of an Genuine BMW radiator and then you build the package from there. Add hoses, sensors, water pumps, thermostats, gaskets, hose clamps, and more. We also sell the Original BMW antifreeze to finish off the job.

    Any problems with the cooling system are likely electrical. Sensors become corroded and fail over time which will send the incorrect signal to the corresponding unit, including the engine computer. Diagnosis of electrical type problems is easy and repair with the OEM Bosch or OE BMW sensors is not too expensive for a car like this. Electrical connections, particularly solder joints, can also become brittle and fail. These are not helped by the intense vibrations of the S14.

    Top Turner Tip for a healthy S14!
    E30 M3s always seem to have cooling problems at the most inconvenient time. If the temp gauge starts rising in the summer months first check and make sure your auxiliary cooling fan is working if it's not it's most likely the switch or the wiring going to the switch. Also remember that the E30 instrument conductor plate can make the gauge read whacky try tapping the gauge if it seems like it's acting up. When it's time to do a water pump (which weeps through a hole on the bottom before it goes completely) take a good look at the radiator too its not expensive and you have to remove it to install the pump anyway.

    Use the options below to build your package.

    This cooling package fits the following BMWs:
