Why settle for stock GM breathers for your pan evac system when a purpose built system is available? Bill Shoquist developed these when it became mandatory to positively retain your breathers. Ever the innovator, Bill designed a system that was not only functional, they are stylish as well! We polish them to a mirror finish and plate them in show quality chrome. These come with all necessary hardware to install, as well as adaptors to 1/2NPT for your collector flutes. All you need is hose and hose ends to complete the install.
