In this video I show you what a misfire situation looks like on my N54 powered BMW 335i.

If you've never experienced a misfire on your car this video will give you an idea of what to expect.

I also go into some theory as to why running colder plugs on your tuned car helps avoid misfiring.

I install a set of NGK plugs and gap them. They are one stage colder than stock. They contain part number 95770.
