For those enthusiasts that want to extract every last pony from their intake system, Perrin has released their completely redesigned V2 cold air intake system for the 02-07 WRX & STI. Perrin's research team has developed their V2 system with a perfectly sized MAF housing and intake plumbing to optimize power without throwing off AFRs or check engine lights as with some competitors products. Perrin has found that optimal airflow comes when the intake filter is relocated to the fender well. This means more consistent temps at the sensor, more consistent runs when dyno tuning, and overall smoother power delivery.
