How to change the Spark plugs on a 2014 BMW X3 F25 N20. 

Extra thin 14mm with 12 points. I already had a deep 14mm socket, but this one is thinner than usual. I got one at autozone. Need about 7 inches of extension, 2 3s and a 1 for the rear most

Thank you, worked perfectly

Thank you!!

Did you use the 14mm or 16mm?

Can you list the tools and parts you purchased on Amazon?

What about bmw x3 2015 does it need the same spark plugs??

14mm
