Filter attaches to the end of your AA blow off/diverter valve to keep debris out
High quality filter that won't fall apart with the high boost pressures
Great add on to your AA blow off valve
You need a 1" plug to run this filter on the end of the valve. The plug blocks the hose running to your intake. Our blow off valve kit comes with this plug. If you are converting your stock blow off valve or a different aftermarket valve, you will need to purchase the 1" plug. If you purchase(d) our valve, you do not need the plug.
