As most of the forum probably knows by now, I've been having some electrical hiccups as of late.

The issues all started when we installed the Magnecor wires a few weeks ago... on the way to the race track, the wires would vibrate loose and fall off at random. We finally got them all to secure on the L/H bank, but last week I had another issue on the R/H bank. Came home and swapped all the R/H wires back to stock, and seemingly fixed the random misfire issues.

Now, all the wires are staying seated (half OEM, half Magnecor) and I'm having issues with the coil packs shorting out once the engine is up to temp (especially on the interstate).

Anyone else have these issues?

 

Magnacores work well on my car. I found holding the wire behind the copper connector with needle nose pliers and rolling the rubber boot back on itself exposes the connector enough to make sure it seats correctly. Then roll the rubber back down over the coil. Do not use any grease. Also the plastic clips on the coil pack primary side break you could check that. Also, check for corrosion on the metal backing of the coils that touches the valve covers. Good luck.

 

I can't be of much help on the why, but if your coils were damaged from shorting let me know. I'll sell you mine for $10 a piece + shipping. I only have 5 though.

 

You have OEM coil packs?

I'll shoot you a PM

 

Yep! And sounds good man.

 

Wouldn't there be a difference between NA and SRT6??

 

Same plug count, plug wires, and plug types... but ya never know.

I'll see if I can find a difference in part numbers.

If having problem with plug wire staying on. You might try taking coil off and install wire till you here the snap. Then just install back.

 

This.

I have magnecor wires on mine and they're seated just fine for the past 15,xxx miles.

 

I am having trouble seating the wires on the plugs. I did the passenger side and wasn't confident that they were seated properly. I did the drivers side and decided to trim the boot back some as it seemed the connector was too far into the boot to properly make the "snap" contact no matter how hard I pushed. I have messed with it most of the day and tomorrow I will finish up but I am having second thoughts about the new wires.

 

Just remove the coil packs, snap the wires in good and tight, and reattach the coil packs to the valve covers.

That's the EASIEST way to do it...

 

Folks, I've been working with 60kV voltages for over...OMG..30 years. (Good Lord, am I really that old?)

Watch the video. Carefully. alaxfire told me about his issues getting his Magnacores to seat on the plugs, but didn't mention the coilpack end.

The Versachem material is the industry standard for this application. I've had a tube in my tool box for 28 of the 30+.

It offers 2 advantages:

1) makes slipping the boots on quite easy
2) provides an insulating layer for those in wet/damp climates.

"Sparingly" is the watchword here.

 

Great video. Always been a consumer misconception to use it on the connections.

 

The issue I had that max mentioned was that NONE of the Magnecor wires seated properly when I initially installed them.
When Max and I were swapping my valve covers for the crinkle black ones, I found it very easy to access the plug ends on the wires.
I was then able to get a 'snap' from all 12 .....
Seems the long boots on the Magnecor's are a bit too squiggly to allow a good seat without grabbing them at the bottom and seating them.

 

I applied the dielectric grease as shown in vid and it helped for the passenger side. They all "seemed" to snap on correctly, but it is harder to tell if they stay connected on the coil packs as the boot has a lip and they seem to creep off a bit. Anyway, i put them all on and started her up, but had a miss/hesitation when throttling up. Took all the damn wires off and put the old ones back on as they have a definitive snap/lock when installing. I have never had such heartburn over plug wires before. I am quite pissed at seemingly wasted time and money. If I hadn't try to modify them to fit better, I would probably send them back, but now they sit in a box until I have another full weekend to mess with them again. cheers
