Default spark plugs, who do you rate?

i recently went to halfords in the hope of buying some pretty decent spark plugs, after a very slim choice on offer i bought a pack of bosch plus ones. £12 for four. I wouldnt have minded paying £12 each. So the question is... Which ones are the best and where to buy them from please? Thanks Arran

After a bit of research myself , i found that NGK irridium plugs will be the ones i'll have in my next service

they are just as good as denso but cheaper

NGK PFR7B's for a modded car or just stick with 6s for a standard car.

Although I see you have a 'Classic' you don't say if there are any engine mods etc.
At 3 quid each they're certainly not platinum tipped so they may need regular checking and re-gapping - a pain in the ar** on the Subaru!
There are plenty of places on -line to get the right plug NGK PFR6B Take them back to Halfords and say they're the wrong grade, then order a set of NGK's on line.

Rather more significantly, he's got a Sport, if I remember right. As such PFR6B's would not be the right plug - although hardly your (or everyone else on the thread's) fault for assuming to the contrary given the lack of info in the top post.
