Hi all, Just doing a bit of tinkering and decided to check my spark plugs. They look ok (a sort of light tan colour) but I have no idea how long they've been in there and thought it may be a good idea to change them. The ones currently in there are NGK R R1 BKR6EK I checked Halfords but my local store doesn't have them in stock at the moment. Are these the ones that BMW recommend? Are there any others just as good? I'm happy to go with what the wisdom on here suggests. Thanks in advance.
