What It Helps Fix

• Heat-related deterioration in the ignition boot

Installation Notes

Verify the vehicle year, make, and model before installation. Match the boot to the existing ignition coil and spark plug connection points, and inspect nearby ignition components for wear, carbon tracking, or cracking during service. Confirm fitment for the specific BMW application before final assembly.
