Anyone built a 3400?

What plugs are you running with the L67 coils? I just bought some "performance" NGK ones to hopefully utilize the upgraded coil packs

I never changed plugs for the coils. My 3800 Monte is still on the factory plugs and the 3400/3100's I've put the L67 coils on are running NGK platinum plugs.
I'd say nothing special.
There is no need to upgrade the plug wires unless you have that itch. The L67 uses the same exact type of wire as the L36 and LA1 do. Also, the L67 and L36 use the same ICM.

Something else I did on my Grand Am and did not do on any of the other 3400/3100 engines, I got those tin spark plug wire heat shields from the 3800's and used them on the 3400. Not so much for the heat shielding, but if you notice the spring on the tip of those, I assume it forces the connector in the plug boot to keep a very positive connection for the spark plug. I doubt they make a big difference (if any at all), but they were damn near free, so I figured why not.
