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 BGR

  1. Use the correct plug type — the BGR requires standard plugs. Upgrading from standard to iridium is acceptable.
  2. Check the electrode gap — verify the gap is 0.8 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.

FAQ

Which spark plugs fit Audi A3 8P BGR?

NGK NGK BKR6E, Bosch Bosch 0242235666, Denso Denso K20PR-U11. All three are OE suppliers and guarantee compatibility with this engine.

How often should spark plugs be replaced on Audi A3 8P?

Every 30 000 km or 2 years, whichever comes first. Iridium plugs (NGK BKR6E) have a longer service life compared to standard nickel plugs.

Can I fit a different type of spark plug in the BGR?

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.
