For 2009–2013 BMW six-cylinder models, including the 128i, 328i, 528i, X3, X5, and Z4, NGK 95712 is the LZFR6AP-11GS spark plug, an OE-quality replacement made in Japan. NGK produces this plug as the OE LZFR6AP-11GS replacement, and it corresponds to BMW OE number 12120037663. Over many ignition cycles, fuel and oil deposits build up on the electrode and the plug gradually wears. A worn or fouled plug can cause reduced power, misfires, and poor fuel economy.

This NGK spark plug carries a 24-month / 24,000-mile warranty.

A spark plug fires the compressed air-fuel charge in its cylinder, and each cylinder uses its own plug. The fastest way to confirm a match is to read the LZFR6AP-11GS stamping on the plugs you remove, or to check the BMW number 12120037663 against your parts records. The fitment covers both rear-wheel-drive and xDrive versions of the 328i and 528i, along with several X3 and Z4 trims.
