I just installed a used Perrin Intake on my 09 WRX...
Current Mods include SPT CBE and stock DP.

any reason there is a little lag around 4k to 4.5 rpms? otherwise i like it and it sounds like i have a BOV installed.

Whats your guys' input?

Get it tuned, that may eliminate that. You may be feeling the ECU pulling time.

You need a tune. You may be running dangerously lean, you have detonation and the ECU is pulling timing in a desperate attempt to save your pistons from assploding. God will kill a kitten every 5 minutes until you get a tune. Think of the kittens...

Buy it from perrin so it comes with the appropriate map, COBB maps don't support perrin intakes
