second time ordering these they work great and fit perfect.

Replaced factory plugs on 2012 X5 N55 with 65k as recommended by BMW. Did not had any issues with old plugs, but after replacement noticed better start and smoother run no change on mpg. Almost year no issues.

I purchased these plugs as a 1-step colder plug for my N54, as they were cheaper than the NGK plugs. So far so good! Idle smoothed out quite a bit and no misfires.

Yes, Bosh no longer makes the ZR5TPP33(S). These seem to work fine in my N55.

I called my local bmw dealer and they wanted $38.00 per plug!! Needless to say i ordered a set of six from fcp euro to go along with my MHD tune same plug number as dealer for a fraction of the cost and my smooth idle has returned.

Worked as they should. Coupled with new coils. No more stumble at idle.

I had four misfires all at once and could barely make it home. I ordered these spark plugs along with the Bosch coil packs and my 2011 E92 335i has been running like new ever since.

Works great.

The Bosch plugs were a snap to swap. I'm at 126,300 and I last changed plug at 66K with these same Bosch plugs. Plugs looked remarkedly good after 60k miles with no loss of mpg or performance. Granted most of my driving is Highway, etc. Great price and warranty program! :)

Replaced my NGK plugs that I had on my '11 335i (N55 engine) for 45k miles. I no longer have the vehicle tuned and apparently the NGK plugs are Out of stock everywhere so the Bosch OEM option is sufficient. So far no issues after 500 miles.
