radio feedback and plug wire shock

I have an 07 JKU that has recently begun getting the whining radio feedback when accelerating. Happens with a/c on or off and increases with radio volume, whether listening to FM or using USB port and Pandora. I checked to see if the spark plug wires were arcing this weekend and found the rear two on the driver side would send a small pulsing shock to my fingers when touching them. They're Mopar wires, presumably stock from the factory as I didn't buy this new. I'm also getting a pronounced ticking from that side of the motor area. Almost sounds like an exhaust leak, but no leaks found, and is louder when cold and quiets as it warms up. Prob not related, but has anyone had similar issues?

Does the frequency of the sound increase with engine rpm?
My first thought is the plug wires are breaking down.
Whether or not that's the cause of what you hear, I'd replace the wires anyway, and the plugs, too, if you think they are original.

See if it makes a difference. It wouldn't be wasted money, considering your JK is about 6 years old.

Agree, if you have an 07, it is about time to replace plugs and wires anyway.

They appear to be newer wires comparing their condition to other mud stained parts throughout the engine bay from the previous owner, but that's not really saying much. It does increase with RPM up to a certain point, but seems to end after first gear. I'm working on the maintenance as I go. Has been running much smoother the past two days after inspecting the plugs and reattaching the wires. I wonder if one of the wires just wasn't all of the way plugged, as the feedback seems to have stopped as well.

Know of any upgraded wire kits? I haven't seen any real mention of ignition upgrades on a JK.
