Query: Nice Intake

I have 2005 Subaru WRX. It was fairly easy to install, there where a few steps like stretching the wiring for the O2 sensor around the heat shield that where fun. I felt more power but had holes in my power band at 4th gear, the check engine light came on. Later I found out what the problem was, it was the O2 sensor. When you change the size, amount, and flux in the air flow it throws the samples the sensor takes out of wack. Usaully you end up burning lean, too much air not enough fuel.I bought Cobb's CPU remapper (AccessPORT) and retuned the computer and everything runs great now. The heat shield is a nice touch and does keep the air flow cooler. The filter itself comes off easy for cleaning. It is sold and fairly easy to install and you get what you are inspecting. If you have a turbo you may need to turn your cpu.
