THE ONLY APPROVED USE OF THIS TOP FOR ROAD CIRCUIT TRACK RACING IS -6 WITH OUR MILD SYSTEM, OTHERWISE EMAIL US!
If this is on an order with a Gen 5+ (current production) can using any fitting larger than -6 or 3/8" barb, it will be modified down to Gen 5 SPEC to work for street / drag strip only.
If this is an upgrade to a separate can, in addition to above, you need to specify what you have in the order notes (Gen 4,5 or 5+; does not fit Gen 3-). If you are not sure, email us a photo.
This sets the can up with a fitting on top of the can instead of the breather.
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.
