Used egr valves vary between vehicles - and whether you call it used, second hand or a replacement, matching the right one matters. These are the details breakers need to match the right part to your car - our request form asks them so you only hear from suppliers with the correct part:
No — the RX-8 uses a rotary Wankel engine (the Renesis 13B-MSP), and rotary engines do not use a conventional EGR valve as found on piston-engined cars; the combustion and gas-flow design of the Wankel means EGR systems of that type were never fitted to any variant of the RX-8. If you are chasing an emissions or idle-related fault on your RX-8, the part you may actually be looking for is more likely the idle air control valve, the oil metering pump, or a component related to the secondary air injection system. It is worth describing your symptoms to a breaker who knows rotary engines, as they will point you toward the correct part.
It is very unlikely to be genuine; no EGR valve was ever factory-fitted to any RX-8 variant in the UK market, because the car exclusively used the rotary 13B-MSP engine which does not incorporate an EGR system. Listings of this kind are almost always the result of catalogue errors, mislabelling, or parts listed against the wrong vehicle. If you have been advised you need an EGR-related repair on your RX-8, we would strongly recommend getting a second opinion from a specialist familiar with rotary engines before purchasing anything.
Because no EGR valve exists on the RX-8, an EGR-related fault code on this car is typically a false or misread result from a generic OBD scanner that does not fully understand the rotary engine's architecture. The parts most commonly responsible for emission and fuelling faults on the RX-8 include the oil metering pump, catalytic converter, oxygen (lambda) sensors, or the secondary air injection system. A rotary-specialist breaker or an independent RX-8 specialist is the best starting point for tracking down the correct replacement component.
Depending on your symptoms, the parts most relevant to emissions and engine management on the RX-8 include the lambda (oxygen) sensors, the catalytic converter, the secondary air pump and its associated valves, and the idle air control valve. The 13B-MSP engine went through detail updates across the RX-8's production run (2003–2012 in the UK, with a significant update around 2008 that brought the Series 2), so always quote your registration to a breaker to ensure the part matches your specific build. Engine management sensors in particular can differ between Series 1 and Series 2 cars, so confirming against your reg is essential before buying used.
