The starting system consists of the rotating electrical motor and solenoid which may be mounted on the starter motor or mounted remotely. The electric motor drives a gear which engages with the engine’s flywheel located at the rear of the motor, when the motor is energized, the motor will turn the engines crankshaft. The starter solenoid is an electric relay, or switch used to provide power to the starter motor or any electrical device that requires high amperage to operate. A low amperage wire winding within the solenoid will create magnetic force when voltage is applies from a remote switch, such as the ignition switch or another type of remote mounted switch. The contacts within the relay carry a high amperage load to run an electric motor or some other type of high load circuit.

The charging system has been required as long as we have had a need for an electrical system and from research it’s been since the requirement of horns in motor vehicle in the early 1900’s. An alternator is a voltage generator that uses mechanical energy to rotate a set of magnets within a field of windings called a stator. The alternating current (AC) voltage created by the spinning magnetic field is converted into a usable direct current (DC) voltage with a rectifier and then regulated by a voltage regulator so that the voltage level in the electrical system stays within a specific operating range. The alternator provides all the voltage needed to operate a vehicle, the battery is only used as a reserve for heavier load conditions, as a voltage source for the engine starting system, and to supply a small amount of voltage to the electromagnets in the alternator which boosts the magnetic field in the alternator and increases voltage output.

Product Features:

• Application matched components ensure the charging system can be returned to like new condition.

More and more performance, less and less consumption – in order to meet the high demands placed on modern engines, automobile manufacturers demand the absolute highest levels of performance from the engine components used. The oil circuit is of central importance here, as only clean engine oil can permanently ensure consistent engine performance. If the circulating oil is not permanently freed of impurities and combustion residues, protection from wear is no longer guaranteed. In the worst case, this may even damage the engine. If you want to play it safe when choosing an oil filter, choose MANN-FILTER. They are designed for modern high-performance oils and can stand up to even the most demanding technical challenges. As the application areas of oil filters and the demands placed on them vary, MANN-FILTER oil filters are available in different designs.

Product Features:

• Outstanding dirt holding capacity
• Prolongs service intervals and continues to meet the technical requirements of high-performance engines
• Offers even faster and optimized oil supply when starting the engine

Litens Automotive is the original equipment supplier to Audi/VW for this decoupling alternator pulley. This replacement pulley is also designed and produced by Litens and is exact in all form, fit, and performance characteristics as the original equipment part (with the exception of not having the car manufacturer’s logo or part number applied to the part). Decoupling pulleys are engine specific and should never be interchanged with other types of pulley technology. The Litens OAD type pulley is designed to free-wheel in one direction and, with an internal spring and damping device, softly engage in the opposite direction. The OAD is designed as a sacrificial part of the front-end accessory drive system, protecting other belt driven component as well as the alternator. The correct decoupler pulley ensures smooth, quiet performance as well as increasing vehicle gas mileage. Under normal driving conditions, the original pulley will require replacement in approx. 60,000 – 70,000 miles.
