Description

The Bosch WR8DC+ spark plug (Mfg Part #12121276283) is engineered to replace worn-out spark plugs, thereby restoring optimal ignition and performance to your vehicle. Over time, spark plug electrodes degrade, resulting in a diminished spark, weaker ignition, and a noticeable decrease in overall performance. Replacing your spark plugs according to the manufacturer's recommended intervals is crucial for maintaining your vehicle's intended performance. This spark plug is priced individually, but it is recommended to replace them in sets for the most effective results. The WR8DC+ is a direct cross-reference for part number 7905. This spark plug is explicitly listed as fitting various BMW models, including the E10 (1602, 2002, 2002tii), E21 (320i), E23 (733i, 735i, L7), E24 (630CSi, 633CSi, 635CSi, M6), and E28 (524td, 528e, 533i, 535i, 535is, M5). Always use the vehicle selector tool to confirm exact fitment for your specific application, as applications may vary based on engine and submodel. The product is covered by a Lifetime Replacement Program.
