Review on 57 2587 Performance Intake Kit by Benjamin Robinson

Installation is easy, instructions are very detailed. The only tricky part was fitting the rubber grommet around the hole the filter goes through. The air recirculation valve is now always audible, even under light loads, but it sounds really good at full throttle. If you don't want your FiST to be invisible, simply install a panel filter. It helps with enough airflow to make the recirculation valve a little more audible than the original. I have a slight whistling/humming noise under light acceleration, something is wrong. probably just grinding somewhere. I'll let it rest a few hundred miles away to see if I can figure out what's causing it.
