.35 mm spark plug gap?

Gapping your plug to this will /and how does it increase performance over a stock gap?

cant see why it would increase performance at all. Smaller spark means potentially longer burn time, or, incomplete burn, and also means less energy req'ed to fire the plug. I dont see how either would increase performance.
With all the aftermarket ignition systems, the gap is increased to make the spark bigger, not the opposite.
IIRC, stock gap (for V6) is .043".

Keeping a low profile while having fun driving my 6.

decreasing the spark plug gap generally shortens the distance the spark has to travel, it neither increases the intensity nor decreases the energy needed to fire the plug. the intensity of the spark is what helps determine the efficiency of the burn, which is why some decrease the gap.

stock gap for the 93-97 2.5L V6 is .039 - .043, per the shop manual.

when i installed my MSD, i found that i had to increase the gap, because of the increase in spark intensity, which can damage the plug if i had left it alone.

don't know. i've never dyno'd the car either before or after.

it did feel a bit more responsive than before i had done the modification, especially so on the mx-6. i'm pretty sure that it's burning the fuel completely now. it runs much better with the gap increased to what MSD suggests than not. well, more so on the probe than the 6.

per their guide for the MSD6 series ignition control module, they recommend a .050 gap for compression ratios up to 9.2:1.

this is IIRC. you can check the manual online at the MSD website.
