Further to the quality info above, I did back to back dyno runs with the "powerflow" (you have it pictured) versus the stock airbox with a KN filter. I got more HP using the stock airbox. After that, I drilled 6x1 inch holes in the bottom of the stock airbox to increase airflow. The engineers at Porsche knew what they we doing when designing all the components to work together. Also, my motor was highly modified (CIS) too.

I also serviced my KN filter each time I changed the oil.

Do a search on this subject as there are TONS of posts.
