Review on 🔥 MAS Set of 8 Ignition Coils DG511 & Motorcraft SP515 SP546 Spark Plug – Compatible with Ford Lincoln Mercury V8 V10 5.4l 6.8l – 3L3E12A366CA 5C1584 C1541 FD-508 DG511 RED DG-511 by Jeremy Jackz

I've looked everywhere for the brand or company MAS, it doesn't exist. You can try to google the company but you won't find anything. MAS is meant to be a cheap foreign fake, I would recommend buying Motorcraft instead. Worst of all, the ads make the customer feel like they are buying Motorcraft coils and spark plugs, but only Motorcraft spark plugs. The coils are made by MAC, you can search for hours and still not find any trace of this company, or reviews of their products. I recommend Motorcraft spark plugs, but NO MAS COILS.
