I noticed Wikoff Chrysler, a supporting vendor, is offering Livewires Performance Spark Plug Wires for the 300C for $110.95. Has anybody tried these yet? Any opinions on whether switching to these wires would make any difference in power or economy?( :biggrin: since our cars are so new)?

Thanks

I was under the impression the '06's didn't have plug wires.

The 06's don't, but the 05's do, unless you convert yours like I did. I just made 8 short (about 9 inches) wires, and plugged them into the spark plug for the cylinder that the coil is sitting on. Does away with the mess going over the top of the engine. It cleans up the top of the engine a bunch, and works great. You can't put the 06 coils on an 05 either. The valve covers and coil primary wire plug is different....3 pins instead of 2, and different coils/bolt pattern. The price of the "Livewires" is pretty good, though. Do they include the boot that plugs into the spark plug? I priced the stock Mopar wires at my local dealer and they wanted $19 each. Ouch!! Bottom line....I doubt that they'd do much good, as the vehicle is too new. I really didn't notice any difference when I put the short wires on. Next month I am going to the races again with another forum member, and we're going to try my wires on his stock ride after he makes a baseline run. That way we'll see if the make any difference or not.

Do the plugs fire at the same time with the stock setup? I don't know. We do know yours now fire at the same time. I am not smart enough to know all the ramifications of this change.

You have lost the redundancy inherent in the stock setup where the twin plugs in each cylinder are "powered" by different coils.

On issues like this I hesitiate to re-engineer a system that Chrysler spent big bucks on in the research and development stage. Ditto on recommended fluids.

Over at LXForums there is an extensive thread on this very issue. Read the thread....it is hogwash from one end to the other. It also confused some members (one guy even thought that, prior to the change, he was not getting two sparks on the compression stroke!).

I'm leaving mine stock.

I don't understand. Why drape those wires from one side to the other if it weren't necessary? I'll be leaving mine alone also, besides, the engine cover hides everything. :nono:

I haven't noticed any difference in idle quality or performance, so far. I am doing my first mileage check right now. Like the 06's, I am losing the redundancy of the stock system, and if I lose a coil, I'll lose the whole cylinder. The stock setup would still fire on 8, but that affected cylinder would only have one plug firing, since the coils fire twice per cycle. I do want to go back to the races in a few weeks, with a fellow forum member who has the stock setup, and have him do a baseline run and then unplug his stock wires and put my shorties in and make a run. If done within an hour or so, it should give us an idea whether it does any good, or not.
If I hear of a mod. and it appears to me to have merit, I give it a try and see for myself. I'll give it a fair shake, and if it doesn't appear to do any good, I'll put the stock system back on. As examples, the MDS "on" light I did works great and helps mileage, as arnoldw can attest. My double wall triple insulated intake duct does little except keep intake air cooler in town, and recovers quicker. On the highway it doesn't appear to do much. Adding another 3 in. duct into the front of the airbox definitely helped, both in town and on the highway. See Phase 3 of my mileage tests and referenced threads at: http://www.300cforums.com/forums/showthread.php?t=9732
Vortex generators (heaven forbid) help keep the Magnum rear window cleaner, but only on the highway....in town, nothing. I am going to add some under the vehicle (in front and in back) and see if that helps any. My rich/lean controller shaved two tenths of a second off my 1/4 mile time, but I still need to do a little more testing with it. Acetone (another heaven forbid) works to some extent....mostly on the highway. My best mileages 30.3 and 29.8 mpg were both achieved using about 6 oz. of acetone in the tank. The most important factor to me is the fact that I love to tinker and experiment, with a goal of better mileage and performance.
