Spark Plugs — Proton Engine Types
Saga/Persona 1.3L VVT uses standard copper or iridium plugs — iridium lasts 60,000 km vs 20,000 km for copper. X50/X70/X90 1.5T TGDI uses iridium plugs rated for 60,000 km. For turbocharged engines, iridium is strongly recommended — misfires under boost cause catalytic converter damage. Always gap-check new plugs before installation. Budget per plug (copper) or (iridium).
