MIA's Description

The Radium Engineering fuel filter kit is an OEM fuel filter replacement for the 1989-2005 Mazda MX-5. This kit features a larger, less restrictive filter that reduces stress on the fuel pump, leading to lower current draw and fuel temperatures. This design also allows for an increase in fuel flow. The filters are compatible with alternate fuels such as methanol, ethanol, and E85.
