NGK PFR7 spark plugs
I have seen these plugs on Ebay at £6.62 each which seems a good price. £29.23 for 4 inc delivery.
Are they the correct fitment?
Item number - 250185343474
Thanks Bob

I am just about to purchase these! Its a good price and judging from their feedback they are the right fitment, there's a few 'scooby' related user names there. Re gap to 0.65 and you will be sorted.

Yes it will fit.
No not all threads are the same, but the "F" in PFR says that it is a 14.0mm thread with a 1.25mm pitch and has a 19mm reach.
The "P" tells you that it's a platinum plug.
The "R" let's you know that it has a resistor fitted
The number "7" is the heat range - A "7" operates at a slightly cooler temp to a "6" so is good for a car that is modified and running more power than std.
The "B" is the design series of the plug
If you have a number at the end then that tells you what the gap was set at from the factory I.E 8=0.8mm 9=0.9mm 10=1.0mm 11=1.1 etc - If there is no number then it is set to 0.7mm

People only reduce the gap when running high boost, as the spark can be blown out!

Just to add,
If you are fitting the cooler plugs to a classic import, then you ought to be using the PFR7G-11 & (then re-gapping to 0.6-0.7mm) not the "7B".
The G series plug is fitted as std from the factory on JDM cars & there have been cases of cars misfiring on the "7B" series & people having to go back to a 6B.
