NGK Vpower vs G power vs Double Platinum

[Ivan Garcia]

So Hondas are particular about their tranny fluid, power steering fluid and coolant.
What about different types of Spark plugs of the same manufacturer?

If the OEM was a double platinum plug, would getting a G power NGK plug, or even a V power plug be bad? Is it more about durability between the plugs? What about the heat dissipation or quality of the spark between the various NGK models.

Thanks

I personally feel that Honda’s are particular on what spark plug they get, but then, my complaining customer based how the car was doing based on MPG.

Saw her driving REAllY fast. Yeah, if you want to drive very fast, then whatever efficiency or power you gained won’t show an improvement at the pump.

By my ear, I think NGK does a fine product.

As for split fired versus singular, are you sure it was originally a v-powered plug? I hear that claimed more often than it’s true.

Share what Honda your asking about. The year, the model.

I see you also asked about durability. On my Toyota I was replacing platinum plugs with Bosch or NGK and was pretty happy for years, but they needed replacing about once a year or every 12,000 miles to really run as good as I felt they should.

When I switched to iridium, whatever brand for me and many of my customers, they were instantly pleased that it didn’t just run good, the car ran “unbelievably” better as my brother said, since I can hear the results after from him more, lol.

I ran my last set of Iridium spark plugs for about 70k miles versus 12k miles. Any iridium spark plugs are pretty good that I’ve tried, but a lot of times only AutoLite is available, they just aren’t as high of a grade as NGK or Bosch, but sometimes, since it’s always available, I run them. I’ll say this, that brand starts amazing, but doesn’t last amazing like better brands.

It’s good to regap any spark plug after a few days of use, they always go out of gap. Platinum and especially copper, were famous for being worse at losing their gap.

I probably end up regapping my plugs still every 6 months. Just be sure if you have to open the gap up, to not pry against the iridium fine tip!

Also, a torque wrench on new spark plugs are a good idea. That quarter term after gently tightening a spark plug in rule only works if they’ve been installed before.
