2003 jeep grand cherokee

This is s silly question but I’m going to ask it anyway.

Where are the spark plugs located on the 2003 jeep grand cherokee 4 liter engine.

Silly to some I suppose.

They’re in the engine at the end of the plug wires.

There may be little rubber seals around the wires to keep the dirt out, so you can’t see the plugs directly.

Yes I realize that they would be at the end of the plug wires. The problem is that in this car the wires are not visible. At least to me. I 've changed plugs on other cars and motorcycles before and they are always easily visible.

passenger side of the engine. All of them after 1999 had a distributerless ignition system and have coils on each plug. There is a hard plastic rail covering the wires to each plug. It doesn’t look like a traditional spark plug setup, but the plugs are there.


I just might stop trying to answer Jeep questions.
