Pleat count & depth play very important roles in filtration - while providing maximum airflow, in a safe and efficient manner.
Expect a 5-7hp realistic gain on the street.
I am very interested in buying two of your filters.
-Do you have any before and after dynos (same car, same day)?
-People report a change in induction sound after installation. Why?
-What country is the filter manufactured in?
