Easy to Install - Great Product
These pre-gapped plugs are great for your engine. It took me 1 hour to replace all my old plugs with these new ones in a V-8 Mercedes 550 engine. EASY. The NKG plugs are running smoothly and sometimes, as with these, small things can make a big difference. I had previously installed Bosch, but after 50,000 miles I felt they needed to be changed because I was seeing degradation in my fuel mileage. I will come back and update this review in 5,000 miles to tell you if and when my mileage has improved. I can already see a upgrade in engine performance just going about 10 miles.

Great Plug!
Got 8 of these plugs for my 2008 Mercedes S550 4Matic. I noticed an increase in acceleration immediately. I've only had them for a week now, so I can't comment on mileage, value, or longevity. But, they were easy to install. I found the torque settings on the NGK website. You probably won't need anti-seize on the plugs, as they are designed to be used without it. Keep in mind that if you do use anti-seize, that your torque settings could change. Would buy this brand again.
