same question as in the title . could you feel a difference ? Are there any proven dyno charts? did you dyno before or after? I am just wondering if they are worth 50.00 for four plugs!

Irridium=lots of wasted money. Go to advance and get NGK's for $3.00 a plug. :thumbup:

i run ngks in my bikes as well as all the hondas and acuras i build/race.
as for the numbers on the plugs the "r" stands for resistor , for less interfernce. the acual # on the plug is the heat range..ex bpr5es-11 would be a resistor plug in your honda with a heat range of 5 and pre gapped to 1.1 mm (.044") a bpr6es-11 is the same style plug 1 heat range colder. ngk plugs run colder the higher the number 4=hot 9=coldest. the #s after the plug -11etc just notes the plug comes pre gapped .bpr5es is same as bpr5es-11 just not pre gapped. i havnt noticed much or any gain from irritium plugs and have acually been told by vortec NOT to use them on forced induction cars.i think the only time i saw any change on the dyno was with a b18c gsr picked up 2-3 ftlbs when we swapped , but it wasnt a good comparison because the original plugs were pretty beat..
