Spark plug question?

[Hemissary]

Sparkplugs in of themselves do not produce more or less power unless you elect to purchase multi-electrode units...in which case you lose power as the initial flame front propagation is shrouded (the more electrodes - the more shrouding).

As far as which replacement plug; copper, iridium, platinum...actual engine performance is the same. It comes down to whether you wish to spend more for a longer service life. But be warned that the GND strap is the same metal throughout...which will degrade as per normal. Ground strap tip rounding (gap increase) is a direct result of the plasma that is created prior to spark propagation; it removes material molecule-by-molecule from both the GND straps and the electrodes.

All multi-GND strap sparkplugs are a sham...period.

My original plugs had 80k miles

That was a lil embarrasing to admit here!

For real. Every 30K or sooner- your HEMI will love you for it.

These coil packs are HOT.
The only change I'd recommend is colder plug for raised HP builds

Now here is my ?...ive been reading about running shorty wires but when i look at the stock wires im lost...looks like the coil pack fires one plug and then the one directly across from it...wont shorty plugs screw up the firing pattern...on a 05 mag 5.7 btw...really wanna run them on my mag's

No it won't. The '05s are set up to fire a "waste" spark in an opposing cylinder on the down stroke of that piston. Meaning, after each cylinder main plug fires, The 2nd plug fires on the down stroke. It was intended to help with emissions. It didn't do much for power but did cause a bit of a "rougher" idle. The "short" plug wires are a poor mans conversion to an '06 and later ignition system. When I say "poor mans" it's because you retain the '05 coil packs and short wires to achieve the goal of firing both plugs in each cylinder at the same time instead of using the newer coil packs and connectors. Extensive testing revealed no real change in power delivered and no emissions problems. Your idle will smooth out a bit however. I've been running these wires for over 4 years and I'll tell you that they work fine.

If/when you want to install these, simply make a diagram of how the OEM wires are connected so that you could easily re-install them if for some reason you need/want to. When you do install these, it should take 15 minutes to get it done. Remove the crossover wires and plug each short wire into it's coil pack and the plug next to it.

As always sir u are the man...thanku...whats the best wires to get again....are the taylor the best.....i have 3 mags so i always do everything triple..so gotta get the right parts first

Taylor are the wires you want. They have different diameters. Get the 8.2mm if you can.

Soooo.....i ordered 3 set of wires and decided to do one of them today at the shop....car has 42000 miles and i never changed the plugs....so changed all 16 plugs to NGK v power and installed wires....fire it up and missing like krazy..motor shaking and engine light on...decide to take it for a spin and it bogs down under acceleration and then the engine light flashes and start dinging....any ideas???

[BigBoy95]

Well finally figured it out...i dropped a spark plug during install and must have cracked it......easy fix
