It depends on how much of a restriction the stock intake is. Generally, there's a restriction at high RPM and the CAI will help there, but it's a nominal increase. Small NA engines just don't see much improvement from bolt ons. But they do sound nice, even if the acceleration doesn't match the volume.jimcardin wrote: ↑Mon Nov 20, 2023 8:12 pm Does cold air intake really increase engine performance? I feel like it's a joke. I read a review about cold air intake for trucks and am wondering whether to install it? Someone give me advice. I need durability on long distances, without too much engine noise
