i did a search and came up with .34-.35 as a recommended plug gap. what do you guys have your gap set at?

ever since i slapped on a MSD unit... i kept it at stock. i totally forgot what i had my spark plug gap at before the MSD unit. i think im experiencing memory loss at age 25.

this is for a DRAG3 b18b set-up.

 

with an MSD box, start at .032" and go up from there until it starts misfiring.

 

Try gapping them at .030.

It works great at .030 for me.

 

It depends how much boost you're running. At 7psi I would keep it around .032-.034. If you turn it up you may have to start gapping them down a little, not much though.

 

So i don't have to start another thread. What should i be gapping plugs at with a stock ignition W/ blaster SS coil....this would be around 7-12 psi...
