Replaces 12639701 2006 2016 Silverado 2007 2016 Review

After trying the replacement ignition part featured in the "Ignition Parts" category, I was thoroughly impressed with its efficiency and effectiveness in my 2006-2016 Silverado and 2007-2016 models... It's clear that the product is top-of-the-line in the automotive industry. i couldn`t be happier with my purchase and would highly recommend it to any TRUCK owner. The one downside is that it is a bit pricey compared to other alternatives, but the quality justifies the cost..

Very disappointed. 8 of these installed in my Silverado but one of them failed within a week. When removing it, the tip broke in the cylinder and now I have a large repair bill. mileage of this product. More details - while removing the remaining 7 plugs from this company, 2 others were about to burn their heads as well. My only option now is to remove the head, a process that usually involves removing the motor. DO NOT think this company's product is a good deal.
