I recently bought used Honda Civic 2009 Prosmatec, the spark plugs need to be changed, can I use normal sparkplugs by NGK instead of Irudim plugs? as Iridium plugs cost alot, and i have to sale this car in the near future. need your suggestion guys.
why do they need to be changed? they last for 1,00,000km
Civic R18 (2006-2012) Came with Factory Fitted Iridium Plugs (NGK Laser Iridium), stick to Iridiums regular copper plugs will effect its performance and Major Bilal is right they last 1,00,000 Kilometers.
