These NGK 5992 Laser Iridium replacement plugs are one step colder than Bosch and are well suited for higher than stock horsepower racing applications. The plug gap must be manually set using a gap tool to the suggested 0.022". The tighter gap and exposed electrode design typically results in fewer misfires at higher power levels than the Bosch plugs. The trade off is a 15-20k mile life span compared to the 20-30k life span of the Bosch plugs. These plugs are compatible with all turbo BMW motors including the N20, N54, N55, S55, and s63tu.
