From what I remeber when I bought mine that is the correct part number so your OK :) I have gone back to the NGK plugs though for my car after seeing a test on the bosch as they arnt up to the quality of the NGKs for the stilo IMO :)

I'm trying the Super 4s after years with NGK. Do you know if NGK produce a 'four pronged electrode' type which would fit the Stilo?

Which NGK plugs are you using? I've had no quibbles with the Super4s - instant noticable low down power increase.

No NGK don't .. but let me tell you what I was told and have seen regarding 3/4 pronged earth conductors on some plugs what happens is the spark is split to the conductors and in fact a single conductor is more efficient ..and Bosch plugs are Not as efficient as NGK with regards to fouling where as NGK I have see for my self when taking out a plug recently which had the largest build up of carbon deposits on any plug I have ever seen in all my years and also the ceramic shroud around the centre electrode was totally disintegrated :eek: but still that plug fired where as a bosch plug would have given up the ghoste long before :)
