Tired of oil leaks from your plastic OEM S65 spark plug tubes? So were we, so we did something about it! VTT Anodized billet 6061 Aluminum S65 spark plug tubes. We took the OEM tubes and redesigned them. Then machined them out of billet 6061, anodized them in black, and added a US-made Viton O-ring with more surface area to ensure a leak-free connection for the life of your S65 that will not break down over time. These are the perfect to upgrade when doing a VC replacement, or upgrading to VTT Billet S65 VCs! These are available in sets of 8. Kit includes: 8 S65 Billet Spark Plug Tubes

Ignition coils are key to the efficiency and performance of your BMW. With a faulty coil the spark plug is not burning the air/fuel mixture properly and that can lead to problems anywhere in the engine and exhaust (including catalytic converters and O2 sensors). Problems with one or more coils will cause a fault code but not always a check engine light. A misfire code may be related to an ignition coil but could be from other things as well. Sometimes a visual inspection of a coil and coil boot will give an indication of a failure. You can also move coils around to different cylinder banks to see if the misfire code follows a suspect coil. We suggest always having one or two coils on hand to keep as spares.
