Iridium and platinum plugs last 2–3× longer than standard copper plugs. Replace them on schedule — worn plugs increase fuel consumption by 3–5% and reduce power output.

Choosing Spark Plugs for A25A-FXS

  1. Use the correct plug type — the A25A-FXS requires iridium plugs. Upgrading from standard to iridium is acceptable.
  2. Check the electrode gap — verify the gap is 1.1 mm before installation.
  3. Torque correctly — for M14x1.25 thread: aluminium head 20–25 Nm, cast iron head 25–30 Nm.
  4. Replace as a full set — always replace all cylinders at once to ensure even combustion across all cylinders.

Can I fit a different type of spark plug in the A25A-FXS?

Upgrading to iridium or platinum is acceptable and gives a slight improvement in cold starts. Do not change the heat range (6) — an incorrect heat range can cause pre-ignition or fouling.
