which is the better plug, iridium or platinum

 

Don't bother, why pay 4x as much for a plug that lasts 2x as long.

Using expensive matches doesn't make a better fire

 

platinum ngk

 

no sorry mate irridium plugs(denso) are the next ones up from platt.plugs irridium is the hardest metal best plugs on the market for street cars

 

+ go to sparkplugs.com think you can get them for 10quid each i did

 

people have probs with Iridium denso's, for most uses, whether it street, or track, most tuners would stick with the Subaru recommended ngk's. Do a search on here mate, it has been discussed over and over and over..................

 

what sort of problems mate?????????

 

Not all of them, but some are not very robust, tips break off, sometimes insulator chips etc, could cost a piston and worse, do a search on here.

 

oops dp.

 

what are the ngk's like then? how much for them?

 

mate, i fitted irridium plugs(denso) got them of fleebay for 30 bucks car done over 400bhp with them and done about 4000k on them no probs at all

 

cheers for the info, just seen some on the said site for same sort of dosh
