STOCK E46 M3 needed for airbox testing

My intake / Airbox is almost ready for testing.

Im looking for a test subject.

Whats involved:

Before and after dyno
Testing of the airbox for 2 weeks
All install is done at PSR
Can be done on a weekend to suit the driver

For the M3 owner that is willing to help out, I will arrange a discount on the final product.

Thanks guys!
