As title says, anyone had a V8 Discovery and got a recommendation on plugs
Ummm which engine??
Sorry, it's a 1998 3.9
NGK Iridium BKR6EIX -- remember set the plug gap to about 15% less than original Landrover spec as LPG put higher demands on plug voltage.
The plug hex size may be smaller than the existing plugs.
Alternative if you do a relatively low mileage fit standard spec NGK copper core plugs, reduce the gap by 15 to 20% and replace them every 10,000
miles.
