Parts for your 2005 Toyota Kluger-Spark plugs

2005 Toyota Kluger spark plugs

Technical sources confirm the 2005 Toyota Kluger runs spark plugs. The model was sold with petrol engines only — the 2.4‑litre 2AZ‑FE inline‑four and the 3.3‑litre 3MZ‑FE V6 — both coil‑on‑plug ignition systems requiring spark plugs. This is supported by Toyota owner’s and repair manuals for the XU20 Kluger/Highlander platforms, along with NGK and Denso catalogue listings for iridium plugs to suit these engines.

On this Kluger, spark plugs ignite the air–fuel mix in each cylinder, keeping starts crisp, fuel use tidy, and emissions in check. Fresh, correct‑spec iridium plugs help the engine idle smoothly, pull strongly up hills, and handle towing or school‑run stop‑starts without a fuss.

As part of regular servicing, spark plug replacement is typically due about every 100,000–160,000 km (iridium), depending on engine and use. Many Aussie and Kiwi owners opt for around the 120,000 km mark, or earlier if there are symptoms.

• Recommended types: Denso SK20R11 or NGK IFR6A11 are commonly specified for both 2AZ‑FE and 3MZ‑FE variants. Use quality iridium plugs to match OEM heat range.
• Gap: Iridium plugs come pre‑gapped around 1.0–1.1 mm. Avoid forcing the gap smaller or larger.
• Torque: Tighten to about 18 N·m on an alloy head. Don’t use anti‑seize on modern plated plugs
