First off, I was skeptic maybe a little hesitant getting an air intake for my 2015 BRZ. After a long extensive research, I finally find what I’m looking for. I made a wise decision to go with injen air intake instead of K&N air intake. Pricing not even close between the two so for $100 less injen win that part. Also its 50 state legal or pending CA. Install was pretty simple, no engine light/cel issues. Drove the car normally after the install maybe a bit over 50 miles. Then started to appreciate the throttle response that the intake gives you, I begin to notice the throttle pedal felt light to touch and the response was quicker than the stock. Its a little bit louder than stock when the throttle opens up 4-6k rpm. Also I notice the injen pcv inlet tube was further and the angle is close to 90 degree not 45 degrees towards the hose. That causes the pcv hose to lean against the back of the power steering unit. But took care that problem with some heat shield matetial to wrap around the rubber hose. Overall it seems that my intake was redesign from the previous unit.
