Well our 2011 Ford Edge had a misfire on cylinder 2 as well as another random misfire. Okay I went to Pep Boys and bought spark plugs for about $40 for all six, spark plug lube $2, PCV valve $5 and upper intake manifold gasket $10. Well, I was going to remake the coils too, but they're $70 apiece at the store. So I decided to buy this 6 pack listed here for the same $70. than 2 hours work. Knock on wood, 10 days later they're still shooting hard, the car is back on track! Please note that I will update this review (trust me!) if these coils work or turn out the way they are. Cheap reels but looked quality so fingers crossed! Don't forget to lubricate the coilpack collars when inserting them into the bushings. So a worthwhile purchase for the time being! Good luck everyone and take care!UPDATE! THESE COILS SUCK, PERIOD! NOT EVEN A MONTH HAS PASSED AND CYLINDER #1 STARTS MISSING! CHEAP PARTS, NEVER AGAIN, SORRY ALL!
