08-24-2003, 06:06 PM
I own a 1994 integra GSR DOHC VTEC and a stock plug gap is 0.050 or (1.3mm) .well i now have a MSD 6A with cap and new ss coil. but am also running a diferent fuel curve.MORE constant. my gap is stock but i was wondering if openinig it would help cause my AIR/FUEL gauge reading is off the scales towards the rich side. the computer program is set up only for headers intake and exhaust only...more air needs more fuel ...but i want to burn it off better.wht would you suggest? 0.060? 10 over? or more?
thx 4 your time

Opening the gap exposes more spark energy (current) to the air/fuel mixture which is good. The negative side of opening the gap is that it puts more strain on the secondary side of your ignition system, i.e. coil, coil wire, cap, rotor, plug wires and spark plugs. I would suggest opening the plugs up in .005 increments. .060 would be about gap I wou;ld run.
