spark plugs

[Wicked_Sludge]

so your running 2 different types of plugs? you must have excellent cylinder balance

non-gapable, mutli-electrode plugs are a waste and can cause drivability problems.

I know Bosch makes some plugs that have 4 points on them and they don't need to be gapped. They look hardcore but they're almost $6 a piece. I bought 2 for my crappier compression cylinders (before working on my engine) and I could tell a difference for sure. Up to you though. Personally when I get some cash I am going to switch the rest of my plugs to the Bosch with the 4 points.

By the way I THINK the proper gap on the plugs are around .44 if I'm not mistaken ?

Stay away from Bosch plugs, period! They don't work well with Ford's EDIS.
They were the reason for my 3.0L misfire, the previous owner had installed
them.

...and you need to move your decimal point on your gap, I'm sure it's .044, instead of .44.......
