Trying Out NGK Ruthenium Spark Plugs (NGK 94567)
Posted: Tue Oct 05, 2021 10:39 am
Hey all, just wanted to share my experience with these spark plugs. The car has 203xxx miles.
I was shopping around for plugs and came across these and decided to give them a try. The longevity perk sold me as I knew the rear bank was going to be a real pain to change out. I'm really glad I bought these. The car is more "awake" and the gas mileage improved from 19.0 average mpg to 21.6 so far. Idle is also much smoother. I did not notice a big change in power. Throttle response improved a little. The real difference comes in smoothness and gas mileage. You get what you pay for and I am glad I spent the money on these NGK Ruthenium's. I got them from Rock Auto for about $9 per plug. I've seen $11 upwards each anywhere else, so Rock Auto is for sure the way to go. I hope this helps.
