Ordered this instead of a full on air intake system in favor of the lesser cost and difference of opinions on whether or not they actually do anything. It arrived on time and in good condition. The install was very quick, about 15 minutes, and very easy. Put this on in conjunction with a throttle body spacer. Between the two it is hard to say that they do anything different. But I will say-without any hard data-it does feel like there is better low end response and torque.
