YOU CANNOT ADD THIS TO A WILD SYSTEM OR A RACE CAN.
This is for our standard size 3" cans only at this time (DOES NOT FIT 3.5" XL)
Order as a conversion to your current catch can order, and we will pre-install this for you, and you will not get the standard Motorsports breather lid or breather.  
Order as a separate lid, and this will come with your order, not installed.
To remove an existing breather lid you will need our can tools pair.
This sets the can up with a sealed top of the can instead of the auxiliary vent.
It is useful for extreme fumes control or visual inspection aid.
