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.

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

Elevate your engine's performance with a choice of compression ratios that suit your needs. Opt for stock compression when conducting a basic engine rebuild or for low boost turbo or supercharger applications. If you plan to run high-performance camshafts, added compression can significantly enhance your engine's capabilities. On the other hand, if you're aiming for a big boost turbo setup, low compression is the way to go. CP and this distributor have collaborated closely to bring you the finest pistons for your high-performance or racing engine. These pistons are meticulously crafted to meet the most rigorous standards and are unrivaled in quality. Piston Specifications: BORE: 84.5mm Rod Length: 135mm Compression Ratio: 8.8:1
