Over time, your engine timing components begin to wear out. Tensioners weaken, chains can stretch, and timing chain guides can wear down. All of these lead to the possibility of the timing chain jumping teeth on the sprockets, causing your timing to shift. This could result in rough idle and reduced engine power, or even complete engine failure. Prevent damage to your engine with new timing components, such as this IWIS timing chain tensioner. Note, we recommend replacing timing components every 100K miles, or sooner, depending on the condition of the timing components.

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.

RACING SPARK PLUG FOR M50/M52/M54 ENGINES
These spark plugs are recommended by BMW Motorsport for use in their DTC racing engines. We find a slight horsepower increase and greatly increased durability over the OEM road car spark plugs in competition use. We attribute the improvements to the fact that these spark plugs are designed for the high temperatures and cylinder pressures encountered in a racing engine. These spark plugs are a direct replacement and come pre-gapped just like the factory road car plugs.
Please note: these plugs are not for the S54 engine in the E46 M3, MZ3, or Z4 M

Sometimes a bad coil may just be a broken or damaged connector boot. This is especially true on cars with a leaking valve cover gasket where the oil has contamintated the rubber boot and the electrical parts inside. This boot can be replaced on its own without having to buy a whole new coil. This part is also useful if you purchased a coil that did not come with a new boot.
