Spark plugs
How often do you guys change your spark plugs on your tuned M5s

DINAN stage two. Changed mine twice so far at 20k each time. They were in bad shape. I changed the gap and went one plug colder this time.

My opinion would be to cut that in half depending on your mods and power levels. The true way of choosing the correct plug with tuning is to check the plug itself to determine air/fuel mixture etc. The spark plug will show a lot of whats going on. Its best to ask your tuner for their recommendation based on their testing they ended up with during their tuning. |
