Hi guys,
do they ever need replacing?Also looking to do my 6 month service shortly and i,ve been using the one step colder NGK PFR7B 4853.Meant to last a couple of years I here but is there a preferred way to clean them up (used to soak them in petrol with my old cars) before screwing back in.Thanks
