Is your air conditioning system faulting by turning on and off at random, leaving you sweating in the hot summer days? The pressure switch shuts off the A/C compressor if the refrigerant pressure is too low or too high to protect your A/C system components from damage. If the switch is faulty, the A/C compressor will shut off at random intervals, or not turn on at all, without cooling the interior cabin. If this is the case with your A/C system, replace your pressure switch to restore cool air.

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).

The best solution for 24v Swapped E30's using an M50, M52, S50, S52US, S54, or Euro S50 Engine with the E34 525i M50 oil pan! The Achilles Motorsports Oil Pan Baffle was designed and manufactured to be used on racing, high-performance track, and street driven cars. Each baffle is precision laser cut from .090" heat-treated aluminum then hand-assembled and test fit to ensure accuracy and ease of installation. Achilles Motorsports' baffle design incorporates dual trap doors and a unique oil deflector that prevents oil from splashing out of the sump under hard braking. Together, these help minimize the sloshing of the oil inside the oil pan and keep oil accumulated around your pickup tube. The factory BMW oil pan doesn't do a very good job of keeping oil accumulated around the oil pick-up tube in high g-force situations. By keeping oil accumulated around the pickup tube you can eliminate the costly loss of oil pressure and potential damage to other vital engine parts commonly caused by high g-forces from hard acceleration and braking and high-speed cornering. Professional welding is required for installation!

NOTE: Due to space limitations, the design of this damper will overdrive your components (water pump, power steering, and alternator) by approximately 10-13%; we highly recommend using underdrive pulleys in your setup Controlling the harmonic resonance of the BMW S14 engine is highly important as RPMs rise, but the ideal configuration of the 4-cylinder motor makes even the most experienced engine builders overlook some fundamental principles of engine harmonics that can be destructive. Harmonics destroy these motors by causing extensive oil pump and crankshaft damage, but the addition of VAC’s Harmonic Damper eliminates the unstable crankshaft harmonic vibrations that cause internal engine wear. By eliminating harmonic vibrations, your S14 engine will be able to produce more horsepower and torque with increased reliability. The VAC/ATI Harmonic Damper is made with an integral pulley, eliminating the need for the additional pulley other models require. Exceeds SFI 18.1 Safety Certification Eliminates problems with lightweight clutch and flywheel assemblies Controls destructive harmonic forces Reduces instances of bearing wear, accessory failure and oil pump failure Includes lightweight VAC Billet Crankshaft Pulley Made in USA ATI Performance Products, Inc. is located in Baltimore, MD, and specializes in producing and maintaining high performance products for street and track applications. Over the years ATI has earned a reputation for its cutting edge technology, attention to detail and rigorous testing under race conditions.

Upgrade Your BMW with ECS Baffled Oil Catch Can

Modern emission regulations require a closed PCV/Breather system for cleaner operation. However, inefficient oil particle capture can lead to excessive oil vapor ingestion, causing carbon buildup, reduced performance, and fuel economy. ECS Tuning's updated ECS Baffled Oil Catch Can, now with an easy-to-empty 1/4" drain fitting, is engineered to collect toxic blow-by gases, minimize carbon deposits, and reduce oil contamination within engine oil. Recirculating oil vapor ensures emissions compliance without venting to the atmosphere.

Key Features:
Highly Efficient Oil Separator: Strategically positioned 4 chamber baffle system maximizes oil/air separation and minimizes oil droplets in the intake tract.
Integrated Dipstick: Knurled and black anodized oil dipstick simplifies oil volume inspection.
Reservoir: Available in 6oz or 8oz capacity with a 1/4" NPT drain plug fitting.
Serviceable: Easily removable baffle plates and drain plug for cleaning.
Easy/Customizable Installation: Combine with the ECS Universal Bracket Kit for simplified installation and adjustable mounting locations.
Leak-Free Fittings: Machined -10AN ORB (O-Ring Boss) fittings available for secure connections (fittings sold separately).
