Slight misfire after changing plugs..thoughts?
Changed the plugs on my 750 today @ 79k miles. i ordered NGK BKR6EQUP iridiums but didn't notice i actually received the IZFR6H11. the BKxxxxx is a multiground (4 prong) plug and the IZxxxx is a single prong. The IZ is rated as an OEM replacement for the 750, but it didn't run all that great when i got it out on the highway and actually misfired once while at about 90mph.
Is anyone else running this plug? Any issues? i think i may take them out and go with the BK's that i ordered originanally. i ran them on my e38 and never had an issue.
Thanks in advance.
