You have to take a big plastic cover off the top of the engine on the passenger side.
You don't see much at all until that is removed - I think the purpose is aerodynamics or just to make the engine area look nice.
Or so that the flat-rate table for auto shops can add a bit of time to spark plug replacement?
Does anyone know for sure - and which auto maker was the first to do it?
For some reason they all followed suit.
A coil pack sits on top of each plug, and replaces what us old timers grew up with - a single ignition coil feeding a distributor with individual HT ignition wires going to each spark plug.
No questioning the merits of that automotive advance, except a failed coil pack might be more serious (and costly) than a degraded ignition wire.
(But minimizes radio interference as a bonus.)
