Hi,
I need to change the sparkplugs on my k20a2 (mild mods, N/A) and I ended up with two options: the NGK IFR7G-11KS (stock OEM part) or the NGK BKR7EIX-11.
Both have an iridium center electrode, pre-gapped to 0.044" and have the same heat range... and are NGK's. The only difference I found is that the IFR7G-11KS costs more than twice as much than the BKR7EIX-11.
Did I miss something? How come those IFR7G-11KS are so freaking expensive?
Thanks for your help!
