The Granatelli Motor Sports screw-in baffle kit is perfect for installing a 1” diameter press-in breather system into your valve covers without requiring welding. They are designed for use on valve covers that do not have breather holes or when an extra one is required in a different location. The kit features a 1 in. double O-ring I.D. female receptacle for use with most push-in breathers, not included. They are baffled to prevent unwanted oil from pushing out of the breather. The baffle requires an appropriately sized 1.375” hole be drilled into the cover and includes a lock nut, sealing washer, O-ring, and threaded baffle.
