A new oxygen sensor can improve driveability and lengthen engine life. Ultimately, you achieve a smoother running engine that is more fuel efficient. Feedback from the oxygen sensor provides closed-loop control of the injected quantity of fuel for optimum air-fuel mixture, enabling virtually complete combustion to take place. Contaminants in gas and certain atmospheric conditions can drastically shorten the life of any oxygen sensor, therefore they should be checked with every periodic maintenance and changed if necessary.

This is the OEM Bosch oxygen sensor for E30 BMW's with the S14 engine. This sensor is mounted in the manifold before the catalytic converter. OEM replacement for BMW # 11781310838.

Bosch is one of the largest OEM producers of Genuine BMW and aftermarket parts in the world, providing parts for almost every major automotive manufacturer. Bosch has likely supplied many of the original electrical (and mechanical) parts for your BMW. Thanks to their quality, high durability, and reliability, you should expect a long service life from Bosch products.

The front seal or crankshaft seal is one of the most difficult to replace. However, they often fail, and when they do, your car will be marking it's territory with little oil drops wherever you park. Apart from making a mess, it can also cause oil to come in contact with the pulley surfaces. Replace yours and keep your oil in your engine.

This ARP Main Stud Kit is designed to replace BMW 11111735525 for the S14 B20, S14B23, S14B25, S14B27 engines found in the E30 M3. One significant advantage of these main studs is their ability to prevent main cap walk, which can occur when the main caps shift or move out of position, potentially causing damage to the engine. In addition, ARP Main Studs can safeguard the threads of your engine block, providing an extra layer of protection against potential damage. When opting for main studs instead of factory bolts, it's important to note that the engine builder should mic the bores. Using studs may require a line hone to ensure proper fitment and alignment. A line hone is a machining process that can be used to resize and reshape the main bearing bores, ensuring that they are perfectly round and concentric. This is crucial for ensuring proper oil clearance and preventing premature bearing wear. By mic'ing the bores and performing a line hone if necessary, engine builders can ensure that the main studs are installed correctly and that the engine will perform reliably and at its best.

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. AAF's Oil Pressure Sensor Relocation Kit allows for an aftermarket low pressure switch as well as oil pressure sensor, or two 1/8' NPT pressure sensors to be installed. This can allow a gauge or light to be on the dash and still log oil pressure in a data logger. This kit also moves the oil pressure sensor away from the engine and onto the chassis (or any other spot) where is it much easier to access, or install larger size diameter sensors. Fits all M20 Engines. Features: 4AN Stainless Steel Braided Line Banjo Bolt and Fitting (installs onto block) 3 Way 1/8' NPT Tee Fitting, for hose from block and 2 sensors. Note: This kit does not come with sensors – the factory low pressure switch can NOT be used. An aftermarket 1/8″ NPT low pressure switch can be used with the factory wire.

Keeping the oil inside your engine is extremely important to performance. Between oil change intervals, your oil can dip to dangerous levels if there is a leak you may not be aware of. The valve cover is an extremely common place for this to happen. Years of exposure to extreme temperature change degrades the gaskets and causes failure. Replace yours to keep your engine oil in your vehicle.

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).

Aftermarket Febi brand.

These mounts are designed for a 1983-1991 E30 BMW 3-series with a 24 valve M50/M52/S50/S52/S54 engine swap with an E21, 2002tii, or VW MK2 Golf brake booster. They use the OEM motor mount bolt holes on the E30 subframe. The mounts are angled with offset bolts to position the engine so that proper drivetrain alignment is maintained. They are used with E36 engine brackets. Revshift motor mounts are made by Revshift in the U.S.A. from high-quality polyurethane. Revshift mounts are the most durable and reliable mounts on the market. CNC machined billet aluminum flanged ends are embedded deep in the urethane which prevents the isolated ends from separating under extreme loads. Utilizing class 14.9 alloy steel removable screws these mounts will hold your engine in place for a lifetime. To further ensure the strength of these mounts we form the threads with a forming tap which creates denser and stronger threads in the billet aluminum end pieces. These mounts have removable screws for ease of installation. We recommend using Loctite on the threads during installation. Revshift Performance Engineering is a high-performance parts manufacturer with a focus on quality, reliability, and performance. Utilizing high-precision machining technologies and their very own Polyurethane Manufacturing Department, every Revshift product is designed, manufactured, and tested in-house at their Detroit, Michigan facility.

Includes all the gaskets and seals needed when rebuilding the S14 cylinder head, along with the head gasket. 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. ​This item fits the following BMWs: 1987-1991 E30 BMW M3

CSF is one of the premier cooling product specialists available on the market today. One item that is often overlooked is the oil cooler. Luckily CSF has taken up the task of upgrading the E30 platform to an external oil cooler. If the oil runs too hot, it can lead to a reduction in wear protection and damage to the head, block, or the turbo system. This unit has 4 cooling cores and fits behind the bumper without any issues.

Fits the following BMWs:
