Performing a spark plug change on the n55 BMW's is a relatively quick job. On the m235i it took 20 mins for gapping and 30-45 mins for the actual replacement. The interval is 50 - 60,00 miles. Hopefully, if you have a misfire, your check engine light comes on so you know if it's the spark plug or ignition coil.
