a bit of advice please chaps;I have the Aero8 annual service coming up soon and am considering a spark plug change.
I know the original plugs are rated 'till approx. 60K miles and I'm nowhere near that but it still seems like a good opportunity to check/replace the originals.
Any recommendations on what to go for?
There are various plugs which come up as suitable fitment from e.g. NGK,Bosch and Denso, amongst others.
I am leaning toward the Iridium tip versions; some have the 'normal' ,one electrode post whilst others (Bosch) have the four post electrode which I understand are supposed to stay effective for longer?
Has anyone fitted new plugs to the M62/4.4 Litre engine recently; if so, what did you use?
I know it may be a little OTT to change this early but am interested to hear opinions....
James
