Recently, we had a modified Nissan GT-R in our workshop suffering from a misfire. Our diagnostics pinpointed the issue to a specific cylinder, and upon removal, we found that the ceramic around the tip of the spark plug had failed. Fortunately, this engine avoided any damage, but we’ve seen cases where broken plug tips have caused serious issues—damaging cylinder bores, valves, and even turbos as debris exits through the exhaust.
Regular preventative spark plug replacement is a simple but crucial step in avoiding these costly failures.



Nissan recommends replacing spark plugs every 5 years or 60,000 miles on a standard GT-R. However, for modified engines, we suggest a more frequent schedule:
✅ 660bhp+ builds – Change plugs every 2 years
✅ 1,000bhp+ builds – Change plugs annually
The NGK Standard GT-R plugs are reliable for cars up to 1,000bhp, offering a stable and consistent spark. For high-power builds exceeding 1,000bhp or track-focused cars, NGK offers a colder Motorsport plug with a smaller tip for improved durability.

Spark plug replacement takes around an hour, and our technicians carefully check the gap on each plug to ensure optimal performance. We keep both plug options in stock, so feel free to contact our team for advice on the best choice for your GT-R.
