Spark Plugs Hey guys,
Haven't posted on here in a while...blew a piston so I've been outta it for a bit. I just want your opinions on what spark plugs I should be using.
Motor-
-ZZ4 block .030 over 10.4:1
-Forged pistons, rods, crank
-Comp cam .535/.544
-Air Gap Intake Manifold
-Holley 750dp
-Stock zz4 L98 aluminum heads with bowl job
What plugs should I use??? I've had Autolite xp103's in there, but I THINK they might've been a hair too cold, because when we pulled the pistons they were loaded up with carbon and ****, and the plugs were always dark. Thanks guys!
