Improved idle and mpg., December 24, 2011

My truck had 96,000 miles on it and the plugs were original. I replaced the plugs and wires because the engine was idleing rough and their seemed to be some electrical interference noise coming through the radio. Changing the plugs and wires solved all my issues. My gas mileage improved by about 1.5-2 mpg's. I am very happy with the level of improvement based on cost.

Iridium is said to be what the best plugs are made of. Even better than platinum. I put them in and it idles smoother, but that happens whenever I put any set of new plugs in. If you like having the best plugs per specification, this is your plug.

Very nice plugs. I have used them in many of my customers cars and they work very good. Great product for getting better MPG and keeping the motor running strong. The iridium is a high quality, long lasting material that will keep you from doing major maintenance. I would highly recommend these plugs.
