I have a 2002 S60 non-turbo. I bought new plugs, and I am wondering what the correct gap should be. They came with 0.7mm gap and my aftermarket manual says to gap them 1.2mm. Is this correct? That seems wide to me. What do you gap them at? These are Denso Platinum TT, PK20TT. Thanks!

 

non turbo has three tip spark plugs. you can use single tip but it won't run as smooth. for one tip, gap is thickness of a credit card 0.028in (0.7mm)

 

None of the plugs offered on Rockauto were three prong, not even the +$7 one. I regapped these to .7 in the meantime. Thanks!
