"Fairly easy install, although seemed to be more bending, pushing, twisting, shoving than should have been necessary. seat-of-the-pants dyno seems to show a bit more torque, who knows. Mated to an SPT exhaust it runs well. Sounds a little raspier/gaspier than I expected, but not at all bothersome unless your foot is on the floor." —Michael S from Boulder, CO bought a K&N 69 Series Typhoon Intake Systems for a 2009 Subaru Impreza, WRX, 2.5L 4-cyl. engine.
"Following the instructions make the installation so much easier. One bit I did have trouble with was screwing in the heat shield. In the instructions there were 2 holes connected to 2 rubber donut gaskets, but I could only use 1 as the other hole was blocked off. This may have been due to changes between the years (I drive a '09 WRX). Overall, really great product with easy installation.
Love the sound of the intake in the higher RPM range as I can hear my factory BPV. Wish there was a lower end sound, but I guess no sound below 2500RPM is ideal for daily driving." —Phill W from San Francisco, CA bought a K&N 69 Series Typhoon Intake Systems for a 2009 Subaru Impreza, WRX, 2.5L 4-cyl. engine.
"Took a while to install, mainly because the stock intake was giving problems. But at the end of the day it was well worth it. I feel some extra power and it sounds great." —Markio W from Bloomfield, CT bought a K&N 69 Series Typhoon Intake Systems for a 2009 Subaru Impreza, 3.0L V6.
