Recirculating Fitting Top

ALL NEW DESIGN FOR 2023! If this is on an order using any fitting larger than -6 or 3/8" barb, it will work for street / drag strip only. This sets the can up with a fitting on top of the can instead of the motorsport breather. It is also safer than the breather top in the event of an emergency overflow to help avoid a dangerous fire. If you add this to a RACE can it will continue to be fully open, and if you add this to DRAFT / PCV can it will continue to be vacuum closing. Choose your pressure vent release fitting size: This should be at least as large as you can inlet fitting. -for crankcase ventilation HP ratings are: -6AN=600HP capacity, -8AN=800, -10AN=1000, and -12AN=1200HP maximum This is not a catch can by itself, you can 'convert' a can on the same order, or get a 'separate kit' for a can you already have. These do not fit early generation 5, or older cans. If you are not sure send a photo. A Mightymouse Solutions Exclusive!
