2008 Toyota Camry spark plugs — what they do and when to change them
Based on Toyota technical literature — the 2008 Camry Owner’s Manual for AU/NZ markets and the factory engine repair manuals for the 2AZ-FE (2.4 L), 2AZ-FXE Hybrid (2.4 L Atkinson), and 2GR-FE (3.5 L V6) — this model uses spark plugs. All these petrol engines rely on iridium long-life plugs and coil-on-plug ignition, so spark plugs are absolutely relevant to a 2008 Toyota Camry.
Spark plugs ignite the air–fuel mix in each cylinder. In the 2008 Camry’s engines, modern iridium-tipped plugs deliver a strong, consistent spark with minimal wear, which helps with smooth idle, decent fuel economy, and reliable cold starts. The car’s ignition coils sit directly over the plugs (no leads to fuss over), so good plugs help keep coil stress and misfires in check.
Toyota specifies long-life iridium plugs for this generation. The replacement interval varies by engine and market schedule, but it’s commonly in the long-service band — typically around 100,000 to 160,000 kilometres. Check the service booklet or the under‑bonnet label for the exact interval that applies to the vehicle. Hybrid models still need the same attention, as their petrol engine also uses standard spark plugs.
- Typical signs they’re due: rough idle, sluggish pick‑up, poorer fuel economy, harder starting, or a check‑engine light with misfire codes.
- Quantity: 4 plugs on the 2.4 L (including Hybrid), 6 plugs on the 3.5 L V6.
When replacing, stick with the correct iridium part number and heat range listed by Toyota for the specific engine. Avoid mixing types or fitting cheaper copper plugs
