Best Plug wires and plug gap

**Intrepidman** · 12-03-2008, 07:33 AM

I'm looking at putting some new plugs and wires in the 02 WS6...I read these forums quite a bit and I know I've seen some good discussions on which plugs are best but I don't remember hearing what the proper gap is, can anyone fill me in.
And I also don't recall any decisive discussion on which plug wires are the best for a lightly modded engine. Anyone care to weigh in?

I gap my plugs at spec. of .060" but many people gap them less. I use MSD wires and like them a lot.

my brother uses msd's also and we gapped his spark plugs to about .55-.56

Crane "Fire Wire".....Less than $50 from Summit

.055

.055 with Iradium Plugs and Accel HOT Spark 300+. They have about 40K on them and run / look like new.

I don't think so, both those gaps are over a 1/2", the plug would not fire correctly.

The proper gap on the stock plugs are .060, on the NGk copper plugs they are .055.

I am running a little more HP and compression than stock so I gap my TR55's at .050 The MSD's are nice wires and the bendable boots lets me keep them off the headers too

a/c delco irridium .040, granetelli wires

**squee** · 12-28-2008, 10:37 PM

The best wires are Granatelli, second is MSD as per the comparison test thats on here somewhere. As far as plugs, I'd say some good NGK or AC Delcos are more than enough...

**totalkos** · 12-28-2008, 11:08 PM

i went with ngk tr55's and msd super conductors. granatellis are too expensive.

im extremely happy, way smoother!

Take a look at this for your choice on wires........
