Default Short Spark Plug Wires for Hemi

I ran accross these on E-bay today. Has anyone seen them before? If so, what purpose do they serve?

Quote:
NEW Taylor BLUE 8.2mm ThunderVolt 50 Shorty Spark Plug Wires. These fit all 03-05 5.7 powered Rams/Durango's, or any 5.7 crate engine. Once installed these convert you current ignition setup over to the Mopar Performance Crate 5.7 Ignition setup. Installation is simple, you just remove your current spark plug wires that cross over the top of the intake and install these. They can only be installed one way so there is no chance of mis-installation.
Couldn't copy the photo. These wires don't run across the top of the engine, but stay on the same side. Help?

I really didnt notice any gains in performance with the wires....Yes all the stock wire will come out, when I took the pic it was starting to get dark and I still had the drivers side to do......I will get new pics for you sometime today..

Thanks for the info. Looks sharp. Did the intake have to come off to get the facory wires out? These wires would be much easier to replace than stock, if the intake stays on.

Kevin,

When you replaced your wires, did you replace the spark plugs too or just the wires?

Yes, I had to remove the Hemi hat and the airbox to remove the old wires, and also to change the plugs......

With the original 'cross over' ignition wires on a 5.7 Hemi,
if an ignition coil fails
the cylinder on which the coil is mounted
will still have one sparkplug firing.

With the short wires
if an ignition coil fails
that cylinder will not have spark on either sparkplugs.

Thanks for the info Keven and HankL. Hadn't considered the cross-over aspect. But then I could fit into a thimble everything I know about how my Hemi works.

Default RE: Short Spark Plug Wires for Hemi

Wow this thread is old...but I have a question about the shorties. Do the coils fire the second plug during the wrong stroke in the adjacent cylinderwith the shorties....since each coil is firing it's own second coil now? From what i've read so far each coil firesthe first plug like normal causing the power stroke and then fires the second plug of the opposite cylinder during the exhaust stroke.

I'm just a little confused...i'm thinking of switching to shorties and don't wanna F anything up or void my powertrain warranty.

There isn't any firing on the exhaust stroke, both plugs in the cylinder fireon the power stroke.For instance, I believe cyl 2 and 7 fire at the same time so the #2 cylinder coil fires the #2 cyl plug via the boot and the #7 cylinder plug via a plug wire. With shorties, the #2 coil fires both plugs in the #2 cylinder. Only thing you loose with shorties is a backup in case a coil goes bad. Idid the 60k wire change and stayed with the long wires but went with MSD 8.5mm and love them. Noticeable difference in idle, smoothness and off the line acceleration. It's some work to wire it up though and the larger wires don't fit in the stock wire track. A shortie installis much easier.

Ohhh..that makes sense, thanks man. Has anyone had issues with any dealerships as far as warranties go?

There was a time when they said the second plug fired x number of degrees later than the first. Others have said that design aspect got scrapped during the design and they now fire at the same time.

Was there ever a "final" determination made on this?

This is all academic because the FACTORY did away with the design, first on the 6.1, then to the rest of the line. The way I see it, its a form of factory upgrade. If I could afford it right now, I would get the conversion kit for the dual coils.
