Spark plug gap

Postby Rambenz » Sat Dec 14, 2013 11:16 am

Hello everybody,

On your LPG cars, what type of plugs do you use and do you set the gap to the oem specs or do you change it ?

Thank you !

I tend to use Iridium equivalent plugs from the same range but usually normal are fine. It depends on the car.. older vehicles I have seen (pre-2000) often require a closer gap.
