The Mishimoto baffled oil catch can kit for 2007–2013 Mazdaspeed3 installs inline with the PCV system to intercept blow-by before it reaches the intercooler. It uses a 2-port compact can with internal baffling, a 50‑micron bronze filter, and a taller 7.5 oz capacity to handle elevated blow-by. The kit includes pre-formed hoses and mounting hardware for direct-fit installation and easier servicing.
