Review on Caldera Thin Wall Spark Plug Socket 12-Point, 14-mm: Ultra-Fit Solution for Precise Spark Plug Work by Brody Jacobs

Fits perfectly and is made of quality material. Just as good as OEM, no OEM price! ! When replacing the Bosch spark plug, the product worked perfectly. There are about 5 metal prongs inside that hook onto the connector unlike traditional rubber sleeves. It was a great design and it worked great. I recommend this product as the quality matches the price. I wouldn't normally consider an outlet, but this is the most stylish outlet I've ever used. All of the sockets I've used in the past had rubber rings that worked fine until the ring started pulling out of the socket. This was a perfect fit for my 2008 BMW 335xi E92 - N54 engine
