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 Julian Perkins

I used to set up candles and coils. However, any experienced person should not attempt to change forks unless you are prepared for the extra work if a fork breaks. Tip: After removing the coil, blow out the spark plug hole. Take a powerful blaster and spray into the hole. Unscrew the fork with the magnetic socket half a turn and insert the blaster into the hole at the top of the fork base. This will soften the soot at the end of the candle. After about an hour, carefully remove the cork.
