I have installed this exceptional product on my used Toyota Aygo 1.0L 2006' model. Got a slight increase in power and a significant improvement in sound quality with a fuel consumption reduce in 5-10 which is essential in little city cars. I have bought 2 more for different cars owned by my cousin.
