Anyone had tried on iriduim tip spark plugs in their GP?. Any problems arising? I tot it might give a better & complete combustion. However, my agent told me that it might cause some problems in the ecu. Anyone heard abt it before?.
Citreon C1 owners claim better performance using these. Check out www.c1oc.co.uk
it well documented there (my missus has a C1)
Not heard on the forum of anyone here using them though.
lmao i don't think an iridium tipped spark plug will make a performance difference in everyday cars. in performance cars, race cars, yes. I think people change for iridium tipped as they last alot longer than an ordinary NGK spark plug.
