So I have a set of fms plug wires! On the passenger side I see that my wires at arcing every once and awhile! What's the best wires for protection from heat??

yep, my fms wires went to crap with not much use.

My FMS wires didn't last very long either. The boots stick out too far and my down pipe eventually got them. Even with DEI sleeves on them and the down pipe wrapped. I'm using Taylor Spiro Pro's now. The much shorter boots make the wires hug the block better. Still using DEI sleeves as well.

I have morose ultra 40's sleeved with the heat sleeves on the boots also.

I did not have a good experience with the straight MSD's, they are a pain to get snapped on.
