the old plugs ive pulled out the cossie puma are labelled NGK R PFR7G 11S. Ive got some old 071's running in it for now but they dont last long in this car.

Ive searched the spark plug threads and not seen these plugs mentioned before for cossies.

Should i try and find an exact match plug from my local motor factors or should i go for another plug??? (and if so what would you recommend for the spec in my sig???)
