156 2.5 V6 Spark plugs?
Can anybody provide me with details on spark plugs required for the
156 2.5 V6? From what I could gather so far it looks like it takes
either the PFR6B (Platinum) or the BKR6EIX (Iridium) from NGK. Can
anyone confirm this or give me details on any other brands? What brand
is fitted as standard?
