Review on 🔥 MAS Ignition Coils DG511 + Motorcraft SP515 SP546 Spark Plugs | Ford Lincoln Mercury V8 V10 4.6l 5.4l 6.8l | 3L3E12A366CA 5C1584 C1541 FD-508 UF-537 (Set of 8) by Marcus Dorgham

I bought these MAS DG511 ignition coils for 2 reasons. The price was great compared to Motocraft and 4.5 stars was a selling point. Item is clean, no problems. The installation went well. Basically no problem. Less than 3 months later I am busy replacing a couple of coils after one failed, replaced and then another failed (3 so far). The problem is that I cannot return the defective ones. I think overall it was maybe a bad batch of coils and not a general issue with the product. It happens. I'm sure 4+ stars for a reason. I just didn't get this set.
