The Cusco oil catch tank for 1991–1997 Mazda RX‑7 (FD3S) is a dedicated oil catch can solution for that chassis. It captures oil and blow‑by vapors to reduce intake contamination and help keep intake components cleaner, making maintenance easier on rotary engines. FD3S‑specific fitment simplifies installation for RX‑7 owners replacing or upgrading crankcase ventilation plumbing during rebuilds or modifications.
