Hi all I have recently changed my plugs on my 2.7 4 cyl my ute it is a dual fuel petrol and LPG, to change the plugs removal of the mixer is nessary. The recommended standard plugs are denso K16R-U the reconmended Irridium type IK16 these are supposed to be longer life and better spark ect. I am aware of issues with plugs on the V6 engines are there issues with the 4 banger, and has anybody used the Iridium plugs I have used them on a 2.1 Volvo with excelent results 80,000 Km plus.
