Hey guys, been doing some work to my truck recently (94 Ram 2500 5.9 Mag 5 speed), and ready to replace the plugs, wires, cap, and rotor. Just curious what y'all recommend? I currently have MOPAR plug wires on it, not sure about the plugs. I have records of what's been done to the truck since 2016, and they haven't been changed in that time, so figuring I should, but don't want to swap them for something inferior.
From my research, the MOPAR wires are 7.5mm. Is that correct? I found some NGK 7mm wires for ~$30 that seem tempting, but not sure about them being smaller...
Looking for what you guys recommend for getting the most power out of a stock ignition system.
Thanks in advance!!

- Distributor cap and rotor should have brass contacts, not aluminum (lasts longer and conductivity is better)
- spark plugs should be standard copper plugs (if you're changing the spark plug wires, please get rid of the metal tubes surrounding each plug - they do nothing but collect dirt/debris around the plugs - pliers and a couple of side to side wiggles pull them right out)
- As for spark plug wires, I like spiro-wound wires - just need well made plug wires

If you haven't already done so, consider replacing the timing chain and gear set with a good double roller timing chain and gear set

 

Go up to 8 mm wires with decent silicone boots. And if they don't already have it put a little dielectric grease in the boots, This will keep the boots from sticking to the plugs the next time you change them.

 

As said, pull those stupid metal shields out, blow the debris out as best you can, then pull plugs.
Any good 8 mm wires. And do not move the distributor base, just pull the cap.
