In my file of replacement parts I have both bkr5e and BCPR5ES showing as replacing it.
So I went here
http://www.sparkplug-crossreference.com ... _PN/RC12YC
and again look at all the ngk that replace it and again all those different heat ranges of the otherwise same ngk can't be right. very frustrating.
and the difference between bkr5e and bkr5e-11 is ?
update: ok going to ngksparkplug.com and entering the 17 hp intek it shows
bkr5es as the regular plug for it
and bkr5e as the pro-v plug
and just found also that BK is ISO type of BCP so all is answered as I find also that -11 means standard gap
