Review on ACDelco 748TT Original Equipment Spark by Andy Edwards

Cadillac supplied them as original equipment on the 556 hp CTS-V sedan. record for a production sedan on road tires. Driven by John Heinrisi, Executive Director of GM's Performance Division. However, these are the only ones I would put back on my car. These connector cables are perfect for my 2009 Cadillac CTS-V. I installed the headers and decided to swap out the connector wires as a precaution. I also installed a DEI 010542 Brown Titanium Protect-A-Boot spark plug guard as an added guarantee that I would not weld the wire. They fit perfectly. Each of these wires were prelubricated and the same length. The DEI Protector was ideal because of its length in relation to the shortness of the plug wires. I would recommend you anytime.
