Best Automotive Spark Plug Wires??
 

I have jacobs 8.5mm plug wires now, but I am having ignition problems. Would anybody recommend another brand that it is better. Taylor msd etc. Thanks

220 Eagle XP, dude have you run continuity tests on your plug wires to determine they are your problem? If so contact Jacobs and they'll replace any bad ones. If you haven't, you should. Hunting around for an ignition problem by buying parts gets expensive fast. I have run Jacobs 8.5's on everything I own for 5 years without a problem, I think they are the best available. Jacobs even warrantied 2 of my plug wires that came out of the loom and burnt through on the headers on my GMC and grounded out, you can't beat their service.
Just my .02

I use Jacobs on one boat MSD on the other. Never had trouble with either as log as the boots are glued on. If you see black lines around the boot voltage is blowing out. The Jacobs are the are the easest to assemble .

Magnacor 8.5mm or 10mm No question at least on a Twin Turbo.........

I have use Jacob's warranty before due to burnt wires on headers. Just trying to get other opions about other brands.

Magnecor are some of the best out there. Check out their site. Very informative. I have these on my truck.
