    They're spark plugs! They fit my 2007 BMW 328xi and I'm pretty sure they're the OEM ones. They were clean and easy to install, nothing wrong with them.

        My car was running sluggish & started staggering. I changed the plugs to these and instant restoration. My Bmw is now performing like I just got it. First trip to work I broke 100mph & didn't go into 6th gear. I love NGK.

        Comments about NGK Laser Iridium Spark Plug (ILZFR6D11):

        My 2007 BMW 328i started misfiring and wanted to stall at idle. I had no codes on the PCM. I had recently redone the valve cover gasket and checked the eccentric cam sensor; therefor, that wasn't the problem. I have 65K miles on the engine, so I decided to change plugs before any other diagnostics. BMW upgraded the plug from a platinum to this iridium plug. Long story short, no more misfires, more power, and better fuel mileage.

            A:

            This would depend on what the manufacturers specifications are for the spark plug gap for your vehicle. I would refer to your vehicle owners/repair manual or contact a local BMW dealership for verification.
