Description

The Bosch High Power Spark Plug, identified by part number FR7KPP332 and BMW part number 12122158252, is engineered as a direct factory replacement. This component is crucial for resolving common engine issues like poor idle, reduced fuel efficiency, and engine misfires, which often stem from worn electrodes or accumulated carbon deposits. By restoring the optimal spark gap and ensuring a clean burn, these plugs help regain lost engine power and smooth out operation. For optimal ignition system performance, it is recommended to replace all serviceable components simultaneously. Replacing spark plugs, wires, and coil packs together ensures the ignition system operates in greater harmony, potentially unlocking hidden horsepower and improving fuel economy. This integrated approach helps bring your vehicle into top operational shape. This specific spark plug is designed to fit various BMW models equipped with the N62 4.8L engine. This includes the E53 X5, E60 550i, E63/E64 650i, and E65/E66 750i/750Li. Always use a vehicle selector to confirm exact fitment for your specific BMW model and year.
