All spark plugs have a "gap" set from the factory. Each plug, however, is made to fit multiple applications. You must always check the plug gap, for your particular application, before installation.

Will this fit a 2008 W211 E550 Mercedes ?

It’s compatible with 2008 Mercedes-Benz E550 base and E550 4matic according to the NGK website. It’s pre gap at .031” (0.8mm).

is this original spark plugs or fake?

I too was worried about this. As far as I can tell the ones that I got are real. I checked the packaging and the markings on the new plugs compared to the original plugs and the markings and location were spot on. They have been in for over a year and I have not had any issues.

Fits perfectly my royalenfield meteor 350

Works great on my Royal Enfield meteor 350. Used to upgrade the factory one. Great price vs dealer. Stock is not platinium therefore I am asumming this is better and has a longer life.

Rapport qualité-prix excellent.

Parfait pour redonner de la jeunesse au moteur de ma hyundai i20 1,2l de 2012. Ce n'est pas la première fois que je les achète et leur durée de vie est bien supérieur à celle de marque champion utilisée par le constructeur...
