A question abt vitz spark plugs, the new vitz with the three cylinder 1 liter engine.
Are iridium plugs necessary for that engine? I mean, really? :s
THe Denso Plug codes are SK20hr11, cannot we just use any other similar plug with a copper tip or the traditional tip w/e it is for that matter, 1000 rupees for a plug is expensive for such a car IMO.
