i noticed every once in a while my car would miss. i was suspecting maybe one of my "new" injectors was bad or something until i popped my hood and noticed my #6 plug wire arcing against the 6th cyl primary on my header. i pulled the wire, and low-and-behold, my 5 month old Ford Racing wire has been burnt right on the boot. so now im in the market for some plug wires. i was reading around and doing some research, and came across these on summit...http://store.summitracing.com/partdetail.asp?autofilter=1&part=TAY-84058&N=700+0&autoview=sku. does anyone have any experience with these? it says they have 100% silicone 2 layer jackets which i guess is supposed to withstand more heat, which is definitely something i'm considering this time around. thanks for the info!
