2003 Infiniti QX4 Ignition CoilReview Fitment Notes to Ensure Proper Fit
Karlyn Ignition Coil
Part Number: 6801-05221203
We had this coil in our car that wasn't firing, so the car was running really rough. We put the new one from Parts Geek in as a replacement and the car runs really smooth now. And the price was very reasonable. We'll get more to change out the rest soon. Our car has 220,000 miles on it so it is time.
