Default Recommended spark plug gap? - 07-07-2016, 03:20 AM
Hey guys
About to install some new Bosch Spark Plugs and Bremi Coils on a friends car. Just wondering what is the recommend spark plug gap? He's running on JB4, CAI, axleback exhaust and octane 98

Cheers!

If it is the stock Bosch 3-prong plugs you can't gap them.

The N55 didn't come with the 3 prong plugs as stock.
