These NGK 5992 Laser Iridium replacement plugs are one step colder than Bosch on N54 engines 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 and N55 Engine.
The listing is for a single plug, you will generally need six when replacing your plugs.
Everyone knows spark plug changes are suggested every 20k miles or so for tuned vehicles and require replacement or regapping for higher than stock power levels. To make that job easier we offer a magnetic spark plug socket tool and an easy to use gapping tool. The magnet socket allows you to install and remove the plugs delicately without damage and our gapping tool lets you quickly set the gap without risk of damaging the plug.
Please Note
When installing the plugs with Precision Raceworks coils on the N55 engine, we recommend setting the gap down to 0.022"
