BOSCH YR7MPP33 OE Fine Wire Double Platinum Spark Plug - Single

Works fine on MW727 engine. Shipping was a bit botched, so I had to use a mixture of the few bosch plugs that came in, and the rest ngk. Car runs fine, but thats more of the seller than the part itself.Be sure to have all plugs in hand before you begin a job, to do it right.

These were the correct spark plugs for my MBZ. R&R of the plugs in the car and it's running fine. Saved a lot of money DIY.

Work on my gl450 2010 Mercedes-Benz

These sparkplugs were an excellent fit to my 2012 Mercedes-Benz GL450. I noticed that they are basically the exact same part that Mercedes sells in their dealers aside from the star logo and the obvious markup on the stealership. Otherwise, they are identical, and they should be given the fact that Bosch makes the original part. You will need 8 of these sparkplugs and to install them a 3/8inch drive-by 5/8-inch spark plug socket, a Torx T30 bit, a 3/8inch ratchet, and if you don’t already have one a Torque wrench. This job is a very easy DIY fix. Some Mercedes out there, such as the V12s, will require 16 sparkplugs instead of 8. However, most Mercedes should only need between 6 to 8 of these. Remember that these sparkplugs do not need any sort of anti-seize or any other sort of grease on the heads. They go in clean. Once installed, the sparkplugs should be torqued to 18 lb-ft of torque.Like I said, with a little bit of patience, time, and the right tools, this is one of the easiest fixes you can do yourself. A week before I installed these I was a little busy and I wanted to see how much a regular shop wanted to install these. First of all, most shops won’t even take customer-provided parts and the parts that they do sell you are considerably more expensive. All in all, they wanted $450 to replace all 8 sparkplugs. They were charging me $150 for the parts and $300 for the labor. Since I thought this was a complete and utter ripoff I decided to wait until I had time to do the job myself. If you decide to do the same, you’ll save yourself a few hundred dollars.As for the performance of these; they completely exceeded my expectations. A few weeks before I installed them I was noticing that the acceleration was not as good as it used to be. The SUV would take forever to take off on any red light. At first I was starting to dread that it might be the throttle body or the throttle position sensor, but upon further inspection I noticed that the original sparkplugs were in bad shape. After I replaced them I immediately felt the difference. The smooth acceleration was back, and I even improved the mpg a little.

Works every time

Ajustó muy bien en mi MB E350, nada de fallos

They are new, in box and stamped made in Germany. These did not fit my 2014 Mercedes C300 Sport AWD.

Pre gapped for my 2008 mercedes 300 they work great
