I got this for my Suzuki Grand Vitara 2.0lt. (not a big engine...) And I could feel the gain in power, plus as of now I got a gain in MPG of 0.5. Maybe is not much but between more power and more fuel efficient I'm 150% satisfied.... I'm getting K&N; for all my cars...Got another flter for a Hyundai SantaFe and the same deal, more power more fuel efficiency.
