Mk3 Petrol Engine, Exhaust and Induction
Hi Guys,
I own a 2015 ST3 with the Mountune MP275 kit fitted. I picked up some Genuine Ford spark plugs for a reasonable price (I didn't need them just yet but bought them early because of the price).
Anyway my car has just gone over 21k miles so i thought id inspect my spark plugs. All...
