Works great in E70 X5

Great, as expected.

Fits BMW 550i perfectly.

great product, car runs like a champ

E93 , great plugs

I wanted to stick with OEM so I went with these. Went in fine, and I have no problems with them. DO NOT put anti-seize on these plugs as the are coated from the factory to prevent corrosion and do not need it.

I forgot to add in my review that the gap values are also slightly different. The 33 is .031 and the 33S is .028

Installed these plugs myself in my N63 550ix this Fall and it's been running great since. Had a cylinder 3 misfire, turns out the coil was shot but the plug looked pretty rough too. I'm past 90k on the clock so I decided to replace all 8 (svc records indicate it was also done at 40k). Was not that hard, honestly hardest part was getting at the coils for cylinders 1 and 5 and reattaching the front-lower intake piping (plastic part) to the intake points behind the grille. Car runs great, hot and cold, and is smoother than it's been since I bought it at 69k. Plugs arrived in perfect shape with correct gapping and washers. Hint: when changing your plugs, poke holes in a piece of cardboard, number them by cylinder, and stick the old plugs in there top end first. Then you can easily inspect them and determine if you have any problem cylinders. Mine were almost all identical except cylinder 3 - looked like the plug had a slight chip and crack, and I think firing it in that state wore the coil down faster than the others. I copped a second coil for the heck of it since I'm sure another will fail eventually, and having one on hand is a cheap solution.

Same as what you get from BMW without the words "BMW."

The way great quality and where super easy to install with the correct socket. Totally recommend them for the perfect oem replacement
