We offer 1-step colder spark plugs for the N54 engine from both NGK and Bosch. We recommend these Iridium tip plugs tuned N54 engines making up to 420 whp. For higher modified cars with more horsepower, our 2-step colder plugs are right for you. We recommend changing spark plugs every 10k miles, or sooner if running E85 or an ethanol blend.
NOTE: Spark plugs need to be gapped properly in order to perform their function as intended. We've included our spark plug gapping tool to assist you in this process.
We will send either Genuine Bosch or Genuine NGK plugs depending on current supply levels in the industry.
