Rated 5 out of 5 by 1 reviewer.
Rated 5 out of 5 by Performs as Advertised My experience has shown Bosch makes the best spark plugs on the planet. When I needed to tune up my 2006 Cadillac CTS-V with 108K miles, the natural choice was Bosch Iridium. The Bosch website shows exactly what plugs fit your application and Pep Boys provided an excellent price and service. Delivered to my door with free shipping. UNBEATABLE! October 7, 2014
