Spark Plug Replacement



What is the purpose of spark plugs? Spark plugs supply the spark that ignites the air & fuel mixture, creating the explosion that makes your engine produce power.

What problems occur with spark plugs? Spark plugs deal with a high amount of heat and contaminates that negatively affect their function. Continued driving past the recommended replacement interval can lead to difficult vehicle start-ups, poor engine performance, and higher fuel consumption.

How is this corrected? Your Nissan Certified Technician will replace the worn-out spark plugs with high-quality, Nissan-approved spark plugs. 

Is it time to schedule your Spark Plug Replacement? If your Nissan has been on the road for over 168,000 km or 7 years, it’s time for a Spark Plug Replacement. Having this service performed by a Nissan Certified Technician will ensure long engine life, lower repair bills, and safe, worry-free driving for years to come.
