Description And Operation: Engine: Notes

The 3.0L (4V) (182 CID) is a 60-degree V-6 engine with dual overhead camshafts (DOHC), four valves per cylinder and sequential multiport fuel injection (SFI). The engine has:

• an aluminum upper intake manifold.
• a lower intake manifold.
• aluminum cylinder heads.
• a cast aluminum upper cylinder block.

The ignition system is electronic (distributorless) with a single ignition coil located above each spark plug. This high-energy ignition system is required for fast-burn combustion.

A unique three-stage intake air system that utilizes two separate plenums, one for each side of the engine. The plenums can be connected through the operation of two special intake manifold tuning (IMT) valves to improve upper RPM power.
