2024 Yamaha VX Limited Tr1 Engine
We use these plugs in our 2024 Yamaha VX limited waverunner with the TR-1 engine. They do NOT improve horsepower or top speed, so if your purchasing for one of those, that is a fools errand. What these plugs DO in fact benefit you is longevity and quicker firing at startups. Some folks are saying they notice quicker throttle response and all and that's just psychological foolery lol. These are an excellent replacement for the oem NKG CR9EB plugs if your looking for less changing intervals and improved startups.

Great product at a great price
Plugs were perfectly packaged for overseas shipping. Arrived in expected time frame. Price was better than expected. Great company to deal with as they supplied timely ongoing updates of processes right up to delivery. Many thanks 👍
