I have a 2011 Mazda 3 i-Sport with a manual transmission and a 2.0 L 4cyl engine. My
warranty is up and I've been thinking about upgrading with some aftermarket parts. My
research leads me to believe that the most logical place to start is with either a cold
air, or short ram air intake, and upgrading the exhaust, however I've also read that
upgrading 4cyl engines aren't exactly worth it and in some cases can do more harm
then good. If I'm looking for a little more power, is it worth it? If so what are some good
parts to look at? (CA resident)
