[QUOTE="UselessPickles, post: 949783, member: 3256"] The purpose of that thing you cut off there is probably to place the effective air inlet of the air box equidistant from the four intake tubes so that they can all suck in equal amounts of air. Cutting it off may cause some imbalance. Cutting another inlet opening into the air box on the opposite side of the existing inlet would balance it out again, and potentially allow more airflow. This is known as "Cdog's air box mod": [URL="https://www.fjrforum.com/forum//index.php?showtopic=105719"]https://www.fjrforum.com/forum//index.php?showtopic=105719[/URL] [/QUOTE]
