WARNING: This page is about a different car, the 2005 Lincoln LS. However, it is still accessible from the selected car via links, so may be relevant.
The 3.0L (4V) (182 CID) is a 60-degree V-6 engine with dual overhead camshafts (DOHC), 4 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 3-stage intake air system that utilizes 2 separate plenums, one for each side of the engine. The plenums can be connected through the operation of 2 special intake manifold tuning (IMT) valves to improve upper rpm power.
