BMW OEM NGK F8S Flex Fuel (E85 Fuel) Spark Plugs SILZKBR8F8S

Mindful packaging A+

Haven’t installed the F8S plugs yet but I was very happy with the packing as there was a Fragile Sticker/taping on the box that said “Do not stack” and the packaging on the inside was nice and tight to keep the plugs from being possibly crushed. Will order from EüroKlässe again just from their customer service and great packaging.

BMW OEM NGK F8S Flex Fuel (E85 Fuel) Spark Plugs SILZKBR8F8S

Modded 2015 M4 with NGK F8S Flex Fuel spark plugs

I had my mechanic install a flex fuel kit on my 2015 BMW M4. We found that the car was not making the horsepower possible. I upgraded to NGK SILZKBR8F8S spark plugs. With E60, the car is making 526 whp and 592 ft/lb torque. The tuner/mechanic said he will use these plugs for all vehicles running E85. I am very happy with these plugs.
