It works on my car. I am getting an increase in travel distance and a decrease in fuel consumption.
it work good
Definitely saves fuel, wish I could've installed them earlier!
If you got a car, buy these! Saves you fuel and you get more mileage. Really cool!
I've used these on three different cars and I think the thing to keep in mind is what your expectations are. I just put one pair on a 1987 Toyota 4. It made the difference. It ain't a turbo kit but it can make a useful difference.
