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.

Awesomeness
Great NGK plugs for my 2007 Mercedes 2007 Sport Sedan!! Percent fit and literally a fraction of the price when store bought. I bought 4 for $20, and advanced auto sells them for almost $15 a piece

You only get 1 plug.
You get 1 plug not a pack of 4. Returned and concerned. The only thing I got going for me is the package it came it was much to small to fit 8 plugs.

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.

Saves gas two ways!
Purchased these to tune up my Mercedes E550. The Bosch OEM plugs run slightly colder (6 rated oem/7 ngk)Not only did my mpg increase 10+ mpg highway but also allows me to run Mid-grade and even 87 octane with out noticeable difference. (if you do run a lower grade octane I would suggest a gas treatment to remove water/moisture from the fuel)saving money per gallon and per mile a win win

12*19,16mm size
it is 12*19,16mm in size for regular Mercedes plug . not short one as the picture on website. it look pretty well-made iridium plug I guess. good product with good price.

Good spark plugs
Bought 8 although only need 6 of those. They work pretty good. Side by side comparison shows should have them replaced long time ago.
