Four spark plugs on the four-cylinder version; six on the V6.
In 2008, the Camry offered two main engine options: a 2.4-liter four-cylinder (2AZ-FE) and a 3.5-liter V6 (2GR-FE). Each engine uses one spark plug per cylinder, so the total count matches the engine’s cylinder count. This matters for maintenance planning and when ordering parts.
Engine options and spark plug counts
The Camry’s two available engines in 2008 determine the plug counts shown below. Use this as a quick reference when buying replacements.
- 2.4L four-cylinder (2AZ-FE): 4 spark plugs
- 3.5L V6 (2GR-FE): 6 spark plugs
In short, your Camry’s plug count is tied to the engine type. If you’re unsure which engine you have, verify the engine code to ensure you purchase the correct number of plugs.
How to verify your engine type
To confirm which engine powers your specific vehicle, use these verification steps. They help ensure you buy the right parts and follow the correct maintenance schedule.
Check the engine code and manuals
Look for an engine code badge on the engine itself, usually near the valve cover or intake manifold, or refer to the owner's manual. If you have access to the VIN, a dealer or reputable online VIN decoder can reveal whether your Camry has the 2AZ-FE or the 2GR-FE engine.
If you’re not sure after checking, contact a Toyota service center with your VIN to confirm the exact engine model and the corresponding spark plug count.
Maintenance note
When replacing spark plugs, follow Toyota’s recommended service intervals for your engine and use the specified plug type and gap. The 2GR-FE often uses iridium plugs, while the 2AZ-FE configurations may use platinum or iridium plugs depending on the trim and market. Always verify part numbers and torque specs for your exact model year.
Summary
Final takeaway: the number of spark plugs you replace on a 2008 Toyota Camry depends on the engine. Four plugs for the four-cylinder 2AZ-FE, six plugs for the 3.5-liter V6 2GR-FE. Confirm your engine type via the engine code or VIN if you’re planning maintenance or purchasing parts, and consult the owner’s manual or a dealer for precise specifications.
