Fit perfect and N55 ran great after install.

As others have mentioned this plug will trigger a drivetrain malfunction even after validating the gap and torque specs.

I was doing a full overhaul of maintenance on my 116K Mile F10 535I. I'm usually an NGK guy but a few people on the forums recommended sticking with the Bosch for a bone stock engine. These seem to be working great and everything's firing smoothly.

OEM plugs are .032. These plugs are .016! However, the package says .032. Clearly wrong pregap from FCP.

I removed the stock Bosch plugs which are gapped at 0.32. These new Bosch plugs come pregapped at .022. Will I get misfires? I'm also running pure stage 2 turbo.

Dear Sirs, Order #R087577046 I have purchased multiple items including 6 Spark Plugs; my mechanic found out one of them are defected during the installation, I contacted the sale and got the refund. After a few week's driving, my car start vibrate and shaking during driving and at the traffic light. I took my car back to the same mechanic, he diagnosed and found out there was another faulty plugs. It costs me $287 to replace that plug, I don't think I would purchase any plugs any more in the future. TF

Installed on my X5 N55 and fairly straight forward, worked like oem. No complaints, FCP Euro for the W!

Perfect fit for my vehicle, no issues during or after install.
