Plugs amd wires. 03 TJ
I'm thinking about making a plug swap. Do you guys have a recommended brand for plugs and wires? Just curious.

You do not have spark plug wires on your 03.

Yep, there are no ignition wires used on 2000 and newer 4.0L engines.

Three good choices include the Autolite APP985, Champion 7034 (both of which are platinums), or the Autolite XP985 which is an iridium tipped plug and the one that will likely outlast your engine. The first two plugs will peform well round 100K miles.

Used APP985....very happy.
