Shoot us a PM if you're interested... we just produced a set for one of our shop cars with the same setup as you, and actually have an extra set of those wires. The resistance is unbelievably low, even with the longer wires.

The double insulator helps prevent breaks in the wire due to mechanical strain. Failures due to current load are reduce with the significantly lower resistance as well. These wires are win win on many levels!

i also noted more difficulty starting engines with the Magnecor 10mm wires, though they do work for higher horsepower builds i never cared for the drawbacks.

the only nice thing about the Magnecors is they are lifetime warranted against breaking the terminals(not sure if they actually document this fact or not). send them back and they will repair them free minus freight costs. that said, they know the "finger" connection internally is a bad design but they continue to make them that way, they are very delicate when removing, a little twisting and they snap off the connector. not good when you are changing your plugs every 5-15k miles.

Can you elaborate a little more about the issue with their connectors? Are you talking about the coil side or the spark plug side? The msd and magnecor spark plug side connectors are very similar in design, and both have a positive click engagement with a secondary "spring" type clip... I've found both to be pretty durable even if you try to wrench the boot off at a weird angle (engagement off angle could cause an issue though). The coil side connectors are definitely more delicate if you try to twist them in an odd way, though they should come off much less frequently. Spark plug boot grease seems to help prevent issues for both connectors (coil and plug) .

each electrical connector inside the boot is attached with long strips of metal commonly called "fingers". when you twist the boot to loosen the wire the fingers twist also which fatigues the metal, giving you only a few install/removals before they snap off.

when you see one fail you will see all the metal fingers balled up together due to the twisting motion.

use some dielectric grease during install to aid in removal, helps buy you a few more tries.

the older magnecor wires were solid like most plug wires, i have no idea why they switched to this poor design or keep it.

this more applies to the FC plug wire set, i haven't used their FD wire set yet, if they have 90* boots then they may have a different connector, more solid. or if you have relocated wires with straight or 45* boots they likely will have the design i mentioned which has put me off on their wires.

From what you're describing this sounds like an FC issue? The spark plug side doesn't have the "fingers" on the FD... only the coil side only. The spark plug side is the same design as most manufacturers and is pretty damn durable. As long as you're careful removing the coil side, and give a *little* care to the spark plug side you should have no issues with these connectors on the FD. Of course if you're really rough on them (or the boots 'weld' themselves on to the plugs with the heat) you risk damaging the connectors/wires if you yank on them off axis. The best thing you can do is use a little boot grease and or dielectric grease on the boots/connectors.

Can you guys make wires for AEM coils mounted near the cruise control location? =)

We've got a couple extra sets here actually for frame-rail-location mounted AEM coils . It's not yet a "website" item but shoot us a PM if you're interested. We've got a number of "secret menu" items that we don't list

I might hit you all up when my AEM coils come in
