please remove the denso plugs people i dont care how many fancy metals are listed on the packet denso plugs are crap
fiat and ngk between them will have desighned the engine and ignition system around the exact ngk plug you have so why change it there cheap enouth much cheaper than the denso iridiums you have i bet:bang: the standard plugs are iridium anyway
my brother is currently working with a team desighning and building a formula student car this is fitted with a bike engine brand new fitted with denso plugs it was running ok in standard form but after a little tuning and induction mods to increase performance it wouldnt start atall changed the plugs for the exact equivalent ngk and now it runs perfectly
and in my experience the vast majority of parts on fiats that are made by denso ecu's sensors and the like are rubish i always look at work to the manufacturer of parts that are failing and what fiat are replasing them with
normaly it's anything made in germany-grande punto door handles door locks
or denso and bosch mainly on electrics sensors ecu's
when these items fail fiat normaly start providing us with magneti mareli parts to replace-stilo ignition coils for example
denso starter motors were responsible for yanking too much current from bateries in punto mk2 face lifts and pandas with 1.2 8v engines stopping the ecu resulting in fiat having to replace them for a diferent brand and then introducing a remap to lower the cutoff voltage
right thats my rant for the day over
please put them in the bin
in answer to the original poster IKR9F8 is right
