"Put these in a 1995 Explorer (120k miles, 4.0 V6) replacing 25k single Bosch Plat plug. Found a questionable wire in the process so did those too. WOW! Smoother, better performance and better mpg. What is not to like? Towed better too. And just passed CA smog with cleaner results then 2 years ago on the single Plat plugs. Guess I'll keep the car a while longer... wish it would die...." posted by: Ford Guy on October 8, 2010

"2000 Chevy 1500 V8. Runs like a brand new truck. Add a good set of wires and you'll add 2mpg to fuel economy. What a tune up" posted by: Kirk on March 3, 2009 view all 5 reviews
