Spark plug Wires question

88fivepointoh · 06-07-2003, 01:01 AM

Hi, I bought a new set of FMS 9mm wires from summit and after about 1000 miles they are causing my car to buck at low RPMS. I took them all off and crimped down the connectors a bit for a better connection but after 100 miles it started again.. what are the best wires for use with MAC UN-EQUAL length headers? I heard about the live wires but not sure what to go with? anyone else have trouble with the FMS wires?

hmm, i been running mine for years with no probs, but i do feel a slight buck at low rpms, i might have to replace mine, but they been good for years.
If i had the money, id go with taylor wires, i see all the big dogs at the track run them, or the msd's.......my 02

I almost bought the FMS ones but heard a couple bad stories, so I bought the Taylor spiro-pro wires for pretty much the same ammount of money and love them, no problems with them. ~Brian

i have been useing msd super conductors for a few years with my mac headers and the only problem i have had is the wires are geting old and starting to arc. had to replace the coil wire this week it was cracked and shorting out. they have them at aoutozone here for like 90 bucks but you can probably find them cheaper.

I'll second (or should I say third

) the vote on MSD super conductors. They have really low resistance and their long, bendable boots help you with header clearance issues.
