Will be doing the valve adjustment over at Coral Docs on August 13 - thinking about putting in a set of new plugs at same time. Anyone familiar with the Denso Iridium plugs - car has 40K and it couldn't hurt.

 

I've always put Iridium II's in mine... the III's were never worth the extra cost

 

Ordered a set of Denso iridium plugs for my 2001 S2000. Received a set of IK22. When I look at the Denso site they recommend IK22G plugs but the heat range is the same - everything is the same except that the electrode is 0.4mm vs 0.8mm on the IK22G.

Are these ok if gapped correctly, what is recommended gap - no turbo or supercharger on car.

Thoughts please

 

I don't gap, I plug-n-play... but I'm crazy like that
