Review on 🔥 Enhanced Performance Motorcraft SP-450 Spark Plug by Edris Holwell

These are factory spark plugs so a lot can be said about the quality of the product. They did exactly what they were supposed to do - screw it into the hole and ignite the fuel-air mixture. I gave four stars because I expect better spark plug packaging these days. I've ordered Denso and NGK spark plugs for our other cars and they always come with little cardboard tubes wrapped around each plug to protect the threads and electrodes. They only came in flimsy cardboard boxes and one box must have fallen off in storage because the top electrode of that connector was pinched all the way down the middle and I had to bend it out with pliers. The other seven were fine. I don't mind checking and/or adjusting the spark plug gap, but the ceramic and copper piece should have some basic protection against handling damage. I wouldn't mind paying an extra cent or two for this little whistle.
