I put similar in my 3.5 carbs/LPG classic and noticed a mid range improvement and smoother on both fuels. If you can find someone with a Halfords trade card they are a lot cheaper.
 
Can't see them making a difference, personally I wouldn't fit anything other than NGK to anything. Quite simply the best and most reliable plugs.

Not me being tight, it's people being stupid paying silly prices. Last time i got a box of NGK plugs for the Porsche they cost me £11.00 for ten at the factors. People are having their eyes poked out by accessory firms.

i was joking matey,yes factors are cheaper,but some bods prefer going and getting their arses spanked.money wise i mean.:D
 
I have a trade card for Halfraud but use a local factorand being a Jock dont like to waste anything
 
not tried them in the RR but got them in the wifes audi and that starts and runs better with them than using standard plugs
 
sorry meant to say they are a NGK plug specially made for lpg vehicles saves the coil packs a load of work
