I can't stop being happy with the purchase, a very good deal!

I bought planet 5 for Izh with CDi ignition, I think it will be perfect for my native Izhov ignition. Tired of buying junk and decided to try these. And the whole problem with starting the motorcycle was due to bad spark plugs, and with these the motorcycle starts immediately and runs smoothly

Dependable Spark Plugs

These spark plugs are perfect for my needs. Based on my observations they are durable and provide reliable ignition for my vehicle. The increased fuel efficiency and smoother engine performance make them worth the price. One downside is that they may not fit all types of vehicles, so be sure to check compatibility before purchasing..

Pros
  • Durable and reliable ignition, improved fuel efficiency, smoother engine performance.
Cons
  • Not universal, check compatibility before purchase.

Marine Parts

I used .030 rated NGK4122 spark plugs on our Evinrude last fall and will forever discard Champion spark plugs. There's a noticeable increase in performance and they don't seem to rust as quickly in the salty air as the champions. I went to the NGK site and looked up my engine to get the spark plug number and then ordered from Revain. Don't forget to make a gap!

Pros
  • Decent Performance
Cons
