Stock airbox horns in ECP filters.

[Master of Faster]

I was thinking about giving this a try since I've got them laying around but they seem awful long inside the ECP filters, like they might restrict airflow too much.

For the guys that are running this setup are you using the full length of the stock pieces or are you shortening them up a bit?

just put them on so as the horn rolls out in side the filter not all the way on this will cut the air supply down .
