The timing chain tensioner from the 1995 E36 M3 is a great upgrade for other Motorsport models - 1988-1991 E30 M3 and 1989-1995 E34 M5! This tensioner virtually eliminates the cold start-up engine rattle so common with the S14 and S38 engines. It makes the whole engine quieter and smoother. Any new tensioner will accomplish that but the S50 tensioner has several new features that make it superior to the original design. This unit also has a internally loaded spring, so installation is much easier than the old style tensioner (no need to squeeze the spring and hold it while installing). Includes oil seal ring (not pictured).

If there is a large amount of oil on the sides of the engine or if you can smell burning oil, chances are it's a bad valve cover gasket. The gasket fails and allows oil to seep down onto the side of the engine and other parts causing a mess and reducing the amount of oil in your engine. This replacement gasket from Elring is perfect to prevent any further oil leaks.

Includes the following Seals:

  • Valve cover gasket

Elring is one of the biggest OEM names in the manufacturing of high quality gaskets that are available for very affordable prices. Elring has supplied many automotive names for years with the gaskets that seal your car's components from day 1 so you can rest assured that these components will last for a long time to come!

We also offer the complete E30 M3 valve cover gasket set

This set of OEM gaskets covers everything you might need when re-sealing the bottom-end of the E30 M3's S14 engine. Using a complete gasket set will save you time and money if you have the engine out of the car and are performing any major repairs with the oil pan and timing covers off the motor. This is the correct S14 bottom-end gasket set, not a re-packaged M10 kit.

This set of gaskets is a both a time and money saver. It includes all of the commonly replaced gaskets, seals, and o-rings when performing this overhaul. Having these on hand instead of chasing them down at the last minute will save you time, money, and frustration. With this area of the engine apart you're going to want or need to replace these items anyway to ensure it's free of fluid and vacuum leaks. This is especially important because some states have very strict emissions regulations and vacuum and oil leaks can lead to failed inspections tests. On newer cars this can also create issues in the on-board diagnostics system. Even if you're not pulling the head this set includes so many valuable parts you'll want to keep this on hand to use for spares.

With more than 100 years in the industry, Elring is one of the oldest names in the European autoparts segment. Delivering OE-quality you can rest assured the job will be done right the first time.

Most people will probably experience a head gasket failure at one point or aanother during vehicle ownership. The signs of a failed head gasket are easy to identify: Milky oil as the coolant mixes in, loss of performance, and sweet smelling, white smoke coming from your tailpipe. It usually happens when the engine is overheated or has a number of miles on it. Replace yours and get your engine running again.

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

Preventative Maintenance: Proactively replacing your rod bearings and bolts with the WPC Performance Kit can prevent potential engine failures. As engines age and accumulate miles, wear and tear become inevitable. These components help you address this issue head-on, preventing costly engine damage and repairs down the road. This is especially crucial for BMW E30 M3 owners who value their investment. Long-Term Cost Savings: While the initial investment in a WPC Performance Rod Bearing Replacement Kit may seem substantial, it's a small price to pay for the long-term benefits. Preventing engine failure and costly repairs can save you thousands of dollars over the life of your vehicle, not to mention the peace of mind that comes with knowing your BMW is built for reliability.
