Ignition Coil Pack & Spark Plug SP479 for Ford F-150 F-250 4.6L 5.4L V8 DG508 DG457 DG472 DG491 Crown Victoria Expedition Mustang Lincoln Mercury Curved Boot Set of 8 Yellow (15% More Energy)

Used to replace the one on our 1997 Ford Expedition and throwing a misfire code. They fixed the issue and have been working great for the last 6 months.

Bought to replace my packs and plugs for my Crown Vic. I do notice a difference and I'm glad I bought them.

I decided to wash my car engine and it was a bad idea. Even with covering some things up and blow drying the engine clean I was met with the dreadful CEL and my engine was jerking and stuttering like crazy. I realized it was more than likely the coil packs and or spark plugs so I bought a cheaper made in China set of 8 from RockAuto. When I first put them on the car it seemed to have solved the issues. However the very next day my car was back to jerking and having engine stutters. I thought for sure it couldn't be the coil packs since they're a day old so I started on a wild goose chase of cleaning/changing sensors, hoses, valves, etc. Nothing seemed to solve the problem. Finally I went back to the coil packs, took a chance, and bought these Bravex ones mostly based on the good reviews. Let me tell you it has completely solved the problem (for now). Its only been a day but so far these are working very well. I will update if one fails or anything but I'm amazed how not all coil packs are created equal. These seem to be a much higher quality than others out there.

So far so good! I don't like that ontrac lost my package, than called and stated it was in Reno.Recently did a tune up in my 98 Expedition, replaced all coils with Napa OEM and Motorcraft copper plugs. Still had a very small idle miss. At 150k, figured it was just this dinosaur of a designed motor.After installing, I instantly noticed at idle the miss was gone! Compared to OEM, these fit perfectly, seem to fit in the well even better with a snugger bite on the plug. I've even gained another MPG. (probably due to small miss, didn't even throw cel) definitely impressed with workmanship build on this product so far. For the price, definitely cannot beat it, seeing as the cost of 8 from brave is equal to ONE OEM at Napa.Update: one died....And they have sent another free of charge!

Working great on my 2000 f150 5.4 Harley D. Old ones were brittle and worn out. Some even broke apart upon removing. These new coils look good in red and perform well. So far so good.

Looks good in stock engine back

Outstanding price!
