Car: 04 fxt stock
I have been hunting for a while now to find the factory spark plug part number. I recently replaced my plugs hoping it would help my stumble at idle and just un smooth acceleration between 2,000-3,500rpm. Well it got worse. The parts store sold me :bkr5eix-11. I check on the same parts store website and they suggest this plug: ILFR6B.
Anyone that knows, I could really use some input from a few members as to what is the CORRECT spark plug for stock.
Thanks,
Colton
