got a set of champion 792 C59yc Racing Plugs free to try on my boosted civic. anyone has experienced with these? should I even try the plugs?

 

what heat range are they? what power are you making?
i noticed these are non-resistor plugs which are not recommended for our cars http://www.hondata.com/techksparkplugs.html

i dont think the old reliable bkr7e has ever let anyone down. and i dont see any advantages to using this plug. its a copper core plug similar to the ngk.

 

heat range is 9. plan to run 35psi on 9.0:1 CR. hoping for 750 whp.

 

get sum ngk's with a heat range of 11
