LQ4 Wire Harness

The 6.0 (6000) is the Paul Bunion breathing engine, great for large engine compartments and is considerably larger than the 4.8 and 5.3. The 6.0 share the heads, intake and exhaust manifolds from the 4.8 and 5.3. The intake is severe and ready for climbing. A taller plenum design / tunnel ram effect, allows the air to hit the intake ports, yielding efficient power, with a snap of torque.

You will lack the diagnostic capability.
