The Billet Sandwich Plate is compatible with all 1971-92 12A and 13B engines, 2004-2008 RX-8 engines and the 1999-2005 MX5 engines.

The Oil Sandwich Plate Adapter unit allows for easy installation of sender units for most popular gauges (1/8-inch female pipe for oil pressure and 3/8-inch female pipe for oil temperature). Due to clearance and fitting restrictions, this adaptor is not suitable for use on the 1993-95 RX-7and 2009+ RX-8′s.

The machined-aluminum adapter will accommodate either mechanical or electrical senders. The adapter mounts immediately below the oil filter assembly and includes a mounting O-ring and detailed installation instructions. Easily installs by simply removing the oil filter! Gauges, senders, and adapter nuts are not included.
