BPR6EIX-LPG is the part number, fits all Rover V-8s from SD1 onwards, but doesn't fit P5B or P6B Rovers ( early ones ) as these use a different reach plug
NGK claim 100,000kms use for this ( iridium plated ) plug, originally developed for Morgans being imported into the USA; fitted with dedicated LPG means these didn't need Federal exhaust emissions testing
Road and Track article: http://www.morgancars-usa.com/randttwo.html
If your Rover V-8 is Dual-Fuel or dedicated LPG, this is the plug to use, but note that the "R" in "BPR" means a resistor-type sparkplug ( don't use resistor-type plug leads or you'll weaken the spark )
