A straight-six engine (also referred to as an inline-six engine; abbreviated I6 or L6) is a piston engine with six cylinders arranged in a straight line along the crankshaft. A straight-six engine has perfect primary and secondary engine balanc ...
internal combustion engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal comb ...

F-series engine. It was used primarily in SUVs because of its large displacement, smoothness, ruggedness and torque.
Technical data
The engine displaced with a bore and stroke measuring , respectively and a 9.0:1 compression ratio; the head used Toyota's narrow-angle
overhead camshaft
An overhead camshaft (OHC) engine is a piston engine in which the camshaft is located in the cylinder head above the combustion chamber. This contrasts with earlier overhead valve engines (OHV), where the camshaft is located below the combustio ...

The 1FZ-F produced at 4400 rpm and at 2800 rpm; its fuel injected counterpart produced at 4600 rpm and at 3200 rpm.
Starting in 1998, the fuel injected version (1FZ-FE) was updated in certain non- US markets. This version of the engine received many updates over the previous version such as a redesigned head, more compact pistons, updated throttle body, an improved intake manifold with longer intake runners, 4 nozzle fuel injectors to improve fuel atomization and direct ignition (via a wasted spark set-up with three dual outlet coils); the engine pictured here is that variant discernible by the intake manifold
An inlet manifold or intake manifold (in American English) is the part of an internal combustion engine that supplies the fuel/air mixture to the cylinder (engine), cylinders. The word ''manifold (engineering), manifold'' comes from the Old Eng ...
and lack of distributor
A distributor is an electric and mechanical device used in the ignition system of older spark-ignition engines. The distributor's main function is to route electricity from the ignition coil to each spark plug at the correct time.
