What is the main benefit of the V-cut in the center electrode?

The V-cut in the center electrode directs the spark to the edge. This helps the spark develop more rapidly, which can lead to improved ignitability, quicker starts, and a smoother idle for your engine.

Are these spark plugs pre-gapped?

This is the LFR6A model, which is a narrower gap version compared to the LFR6A-11. While they are designed for OE applications, it's always a good practice to check the gap against your vehicle's specifications before installation.

What does the trivalent metal plating do?

The trivalent metal plating provides superior resistance to corrosion and seizing. This makes the spark plugs easier to install and remove, especially after they've been in service for a while.

Product Details

When it's time to tune up your Yamaha WaveRunner, making sure you have the right spark plugs is key to getting it running smoothly. These NGK V-Power spark plugs are designed to replace your original equipment, offering reliable performance and improved ignitability over standard nickel plugs. They are a solid option for a wide range of Yamaha WaveRunner models, from the FX SHO series to the AR240 HO.

What sets these plugs apart is the special V-cut in the center electrode. This design helps direct the spark to the edge, allowing it to develop more rapidly. This means quicker starts and a smoother idle for your watercraft. NGK also uses a high-grade alumina silicate ceramic insulator, which creates a stronger core for better dielectric performance and heat transfer. Plus, the trivalent metal plating on the exterior helps resist corrosion and seizing, making installation and future removal easier.

This box contains four LFR6A spark plugs, which is a narrower gap version compared to the LFR6A-11. Make sure these are the correct plugs for your specific Yamaha model before installation.
