I use the 809 - which I believe is the RA6HC or is it RA8HC.
The funny thing is, the NGK's DPR8EA-9 and DPR7EA-9 (hotter) both equate to the same champion plug.
Anyway - the same cheapass champion is OK for me. i tend to erroneously change them far before they are done ... so no sense spending the extra $$$ when i'd toss it just the same.
Cool.
