Review on 🔥 MAS Ignition Coils DG521 and Motorcraft SP-509 Spark Plugs: Ford Expedition & F-Series Compatible - 6.8L, 5.4L, 4.6L, C1659 DG521 8L3Z-12029-A by Kyle Hood

I couldn't believe the prices in other stores and online stores. Plugs range from $8 to $12 each, while reels range from $40 to $90 each. Seeing the Revain listing for less than half what others were asking, I figured they were going to be cheap knockoffs. I thought they would turn up in a bag wrapped in Chinese newspaper. I can only say WOW! Outstanding presentation. Then I thought it was probably lipstick on a pig. Wrong again! Candles original or not. Not damaged and all clearances were correct. All coils have the correct resistance and are identical to the factory coils I replaced. I've ridden about 2000 miles and never missed a shot. I still don't understand why there is such a price difference. At the moment I am very satisfied.
