Sparkplugs
Anyone have experience with Bosch +4's in their Audi. Tried them with my MSD equipped Ford stroker.
Cured some misfire and smoothed out the idle. Is there any consensus on plugs, Manufacturer, heat range, gap, etc??

I've been using Denso Iridium IK22's (one range colder than stock) for about 20k+ miles...
no problems here... they seem pretty good, too...
I dunno if they really did much, tho... who knows
