A simple yet effective upgrade, these Bav Auto High-Performance Ignition Coils feature modified core windings that offer increased firepower and promote a faster, more efficient burn. The result is greater low-end torque and increased horsepower in the mid to top-end. When used in a properly functioning engine, a noticeable difference can be felt. In addition to better torque and horsepower, fuel economy is also improved! These coils come with new spark plug boots. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

Excessive driveline vibration is caused by one of a few things, but more than likely, it is the mounts in your vehicle. They keep your engine and transmission secure for more positive shifting and driveline triangulation as well as absorbing vibration. If any of these are occuring in your BMW, it's time to examine your mounts.

Loosen the reins on your thoroughbred with our 8 mm ignition wires. Stock Ignition wires have built-in resistors that reduce voltage to your spark plugs. That's like keeping a tight rein on a thoroughbred race horse -- it wants to run faster but can't. Our 8mm wires loosen those reins, providing the hotter spark your BMW craves. Both the wires and boots use a spiral core magnetic suppression conductor to provide a higher spark voltage for maximum combustion efficiency. And they're insulated with 8mm of pure silicone to completely eliminate interference. Be aware that due to the increased size of the wire these will not fit in the factory wiring loom. From 1974 to 2019, Bavarian Autosport was one of the premier vendors for BMW and MINI auto parts. We are happy to preserve the Bav Auto legacy by continuing to carry their high-quality products into the future. All Bav Auto parts will remain unchanged in design and sourced from the same OEM suppliers to ensure long-lasting reliability. We trust these parts, accessories, and upgrades so confidently that we back every Bavarian Autosport branded component with a 2-year warranty.

These are the stock rubber motor mounts for the E30 M20 engine - 325e and 325i. These are the original spec full rubber mounts. The M20 has a fatal flaw especially when the motor mounts are worn. The engine can shift and contact other things in the engine compartment, mostly cooling-related parts. This is especially troublesome on the 1984-1987 models as the alternator belt and blades can cut into the lower radiator hose. Don't neglect your motor mounts! A worn motor mount allows the engine to twist and shift around. The harder you're driving the more shift will occur. Twisting of the engine can also lead to shifting problems as the transmission twists with it. There are countless issues related to worn or compressed motor mounts so don't overlook these as a regular replacement item (every 50,000 miles).

For more serious track or street cars we recommend our HD motor mount kit with reinforcing cups - click here. These are a stiffer mount to begin with (coming from the Euro 635CSi) and the aluminum cups give additional strength especially for the side-side shearing loads that you get from cornering.

These stock rubber motor mounts are sold per mount .

This item fits the following BMWs:
1984-1991 E30 BMW 325e 325es 325i 325ic 325is

This is the sealing o-ring used for many oil cooler kits on various BMW models. They're also a prime source for oil leaks because the o-ring gets 'flat' or shrinks or becomes damaged. These are usually easy to change though which puts an end to annoying small oil leaks.
