Review on AEM 21-678C Gun Metal Cold Air Intake System Review by Jason Sergeantson

AEM is a really well known brand and this air intake is what 9/10 Evo owners have on their X. Air accounts for about 20% more. Affects the car so you'll notice a slightly more fuel efficient car after a system reset and it's totally worth the price and the extra power (around 20hp) and torque. The only drawback (less than 1 star) is the plastic connection. The original Evo air intake should fit, but the hole size is about 2mm larger than it should be, so it still separates from the original intake. Works well at first, but wears off after a while. However, highly recommended! best out there
