BOSCH YR7MPP33 OE Fine Wire Double Platinum Spark Plug - Single

I purchased 6 of these BOSCH YR7MPP33 spark plugs to replace the originals in my Mercedes C300, and they worked flawlessly. Installation was straightforward, and they fit perfectly with no issues. Right after replacing the plugs, I noticed smoother acceleration, improved fuel efficiency, and overall better engine responsiveness. These are high-quality double platinum plugs, and it shows — they deliver consistent performance and are built to last. If you're looking for a reliable OEM replacement that matches Mercedes specs, this is the one. Highly recommend for anyone doing spark plug maintenance on a C300 or similar models!

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 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.

Great

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.

These fit mt 2009 C300. Don't let other reviews fool you. While this Install was very simple if you have the tools it is by no means a 30 minute job. Taking your time its about and hour or so. The plugs need to be torqued to 25 NM or 18 ft lbs. The ignition coils torqued to 9 NM or 6 ft lbs. Had tight basically. I removed all but one of the wires. The front passenger side didn't need to be removed. The others did. You need to be careful there is a plastic pin that a small flathead screwdriver can pry down. Then you can remove. In some cases it was tricky. save hundreds of dollars and do this yourself.

309 miles in, so far so good runs smooth

Bhai swift ka pick up , speed sab improve ho gayi h

Tres bonne bougie de marque. Une techno performante. Montage d origine qui a déjà duré plus de 100 000km et c est reparti pour autant. Vaut son prix sans hesitation.

Montate su DR5-EVO5 126/128cv 1.6 benzina/GPL del 2019-20, Motore efficiente sia a basse e alte temperature e miglior consumi di carburante. Dopo 10000 km si è danneggiata una candela (al minimo perdeva colpi) sostituita, ora va bene.

Good spark plugs that are made in Germany! Replaced the plugs on my Mercedes-Benz C300 and it definitely gets better consumption now.

Supersmidigt och leverans hem till dörren. Kunde inte bli bättre.
