Ridex EGR Exhaust Gas Recirculation Valve • MX-5 MK3/NC (06-15)

Product Description

EGR Valve (Exhaust Gas Recirculation Module) (RIDEX Part No. 4198E0170 — OE ref LFE2-20-300).

Recirculates a measured amount of exhaust gas back into the intake to lower combustion temperatures, reduce NOx emissions, and stabilise idle/part-throttle operation.

You’ll typically see it on the Mazda MX-5 (NC) 1.8/2.0 (2005–2015); see our compatibility table or verify fitment using VIN/chassis.

Commonly replaced if you’re seeing EGR-related fault codes (e.g., P0401/P0402), rough idle, hesitation, stalling, or heavy carbon build-up in the valve passage.

What’s Included
1 × EGR Valve (electric). Torque specifications and installation instructions are not included—refer to the Mazda workshop manual, or get in touch with our technical team for support.
