hi i wanna know if these r good for corolla altis 1.8 2010? (1zzfe)
Denso K16R-U11 in copper and Denso Ik16 in irridium?if not kindly mention the right plugs for it ..
i'll also be looking for the answers from experts here. @syncview@SGR_GTR @xulfiqar @hash4u
Both plugs work, only difference is your spark plug change interval increases due to long life of iridium plugs
Both are almost same spark plug only difference is ik16 will last very very long
