I just did a some research on sparkplugs since I was need to replace mine. I stoped on Bosh Platinum2 or Platinum4. Those sparkplugs does not require re-gap ever (according to reviews). I own Subaru Outback '97 and my service manual recomend to change sparkplugs every 100K, so, I decided to select more expensive, but better quality.
When I had the dealer replace my pistons for "piston slap" I asked them to change the plugs since they had the engine apart. They used standard plugs as advised by SOA.
