Which brand of spark plugs will be more suitable for Mehran and what will be the price of three spark plugs?
it depends on the type of spark plug u wantcopper ,platinum or iridium.
If both brands plugs are copper, which brand would be better and why? (for a corolla 1.5 5afe)
if both are copper there both almost equally good,though ngk has slightly longer life as comapred to denso
Are platinum and Iridium plugs easily available?
yes they are
NGK for copper they give better responceDenso are good in iridiums
What is the mileage after which copper spark plugs shud be changed?Secondly I think that copper is more good conductor as compared to Iridium..... Then why are Iridium plugs expensive and what are their advantages?
Iridium Plugs give smooth acceleration and better mileage then copper plugs...
