I was looking all day yesterday for that specific info as I have all the specs on the plug... I am gonna research it some more today to see if I can find a copper core replacement for you guys... But the depth of the plug is what I am having a hard time with as most of the plugs with that depth are either iridium or platinum plugs...

those are iridium plugs but they are only 11.99 and they are 1 step colder.
I could never find the copper plugs for the 9. some people say you dont even need 1 step colder for the 9 as they all ready run a cold plug. but the denso plugs are working great for me.
IKH24 is the part number

Just spoke with NGK tech, and Denso tech and they do not make a conventional copper plug in the stock or 1 step colder heat range yet... I am going to call Champion and Autolite and see what they say... Denso had a spec match but it was a 20 heat range (22 is stock). Champion had a spec match but a different heat range also... Autolite is a no go too...
