ALL NEW DESIGN FOR 2023!
THE ONLY APPROVED USE OF THIS TOP FOR ROAD CIRCUIT TRACK RACING IS -6 or MED Q/C WITH OUR MILD SYSTEM, OTHERWISE EMAIL US! 
Available for our standard 3" and 3.5" XL can
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.
This will include the Fitting type lid, the size fitting chosen above, a 45* hose end, 3ft of hose, a hose barb adapter, and a grommet for mounting, and Instructions HERE
It is useful for extreme fumes control or visual inspection aid.
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.
