The cylinder firing order for Toyota's 4.7 L V8 is 1-8-4-3-6-5-7-2, with cylinders numbered 1-4 on the left (driver) bank and 5-8 on the right (passenger) bank. This arrangement guides ignition timing and spark plug wiring for the 2UZ-FE family used in many Toyota/Lexus applications.
Cylinder numbering layout
For reference, when looking at the engine from the front, the left bank (driver side in most markets) carries cylinders 1 through 4 from front to rear, while the right bank carries cylinders 5 through 8 from front to rear.
- Left bank (driver side): cylinders 1, 2, 3, 4 from front to rear
- Right bank (passenger side): cylinders 5, 6, 7, 8 from front to rear
Understanding this layout helps you map ignition components and perform maintenance or diagnostics accurately.
Firing order
The sequence in which the cylinders fire on the 4.7 L V8 is:
- 1
- 8
- 4
- 3
- 6
- 5
- 7
- 2
This firing order is typical for the 2UZ-FE family that powers the 4.7 L V8, and it is important for proper ignition wiring and timing alignment across the engine.
Practical implications
When replacing spark plug wires, spark plug coils, or performing timing-related work, follow the indicated cylinder numbering and firing sequence to avoid misfires and ensure balanced engine operation.
Summary: The 4.7 L Toyota V8 uses left-bank cylinders 1–4 and right-bank cylinders 5–8, with a firing order of 1-8-4-3-6-5-7-2. This arrangement supports reliable ignition timing and engine balance across the 90-degree V8 configuration.
