Radium Engineering Fluid Lock Catch Can Kit, PCV - Mazda RX-7 (FD3S)
Radium Engineering builds its catch cans to motorsport grade tolerances using CNC machined billet aluminium, and this PCV kit brings the patented Fluid Lock® system to the Mazda RX-7. It stops collected oil and moisture from ever reaching your intake, keeping inlet tracts, throttle body and intercooler piping clean.
