want 2 know the difference between iridium tipped and platinum tipped which ones better and why???? this is 4 a standard rst,

 

they are both good conductors of electricity and will probally be good enough for any rst

 

but which ones better???

 

If your car isnt fouling or you aint running extremely high boost that will blow out ya spark then why worry? sufsRS, what rst ya got, im from york but work all over west yorkshire, dews batley wakey, leeds ect

 

The center electrode is fine wire platinum for better starts, superior acceleration and better fuel econom. This plug is basically an efficient plug.
Iridium plugs , the latest evolution of spark plug technology. The iridium center electrode is both stronger and harder than platinum. This allows NGK engineers to design an ultra-fine (0.6mm)center electrode reducing the voltage requirement for spark. This allows for a brighter, stronger spark from your existing ignition system. The ground electrode has a tapered cut at the firing end which reduces quenching for better flame core growth and increased ignitability. The combination of fine wire center electrode and tapered cut ground will increase performance, improve acceleration, and fuel efficiency
found it in a search so iridium is best

 

nice one white cab thats what i wanted 2 hear brilliant iridium it is!!!! twin45s ive got a red rst h plate u may a seen it, wot u drivin????

 

its off the road for cossie managment put a 2l zvh lump in but didnt go quite to plan
so i am just sticking to the cvh and a bit of head and gearbox work.it has a navy mohair hood and gleaming bodywork just need to get the cash to finish it off so some night shifts and 7 day weeks might be on the cards

 

I think I've read somewhere that the new iridium plugs are not recomended for cossies & erst, not sure why though, maybee someone could advise

Why not go for a standard plug if its for a standard rst The ford agp071c plug will be PLENTY good enough, finis code 1120834
