Parts for your 2016 Subaru Impreza-Egr valve

2016 Subaru Impreza EGR Valve — Is It Fitted, and Does It Need Servicing?

Short answer: the 2016 Subaru Impreza (GJ/GP chassis, 2.0-litre FB20 port-injected engine) does not use an EGR valve. This is backed by Subaru’s own technical literature: the Impreza 2012–2016 Service Manual (FB20 Engine, Emission Control section) shows no EGR circuit or component, the 2012MY Impreza New Model/Technical Training material notes the FB20 uses variable valve timing strategies to manage internal exhaust gas residuals instead of an external EGR assembly, and the 2017MY Impreza documentation for the updated FB20D (direct injection) specifically calls out the introduction of a cooled EGR system, highlighting that earlier FB20 applications didn’t have it. Genuine Subaru parts catalogues for 2016 Impreza VIN ranges also contain no listing for an EGR valve on this model.

Why no EGR valve on this one? Subaru’s FB20 as fitted to the 2016 Impreza meets emissions targets without external EGR by leaning on dual AVCS (variable valve timing) to retain a controlled amount of exhaust gas in-cylinder, optimising combustion temperatures and NOx, along with efficient port fuel injection and combustion chamber/tumble design. That approach reduces hardware complexity and eliminates a common soot and clog point you’d see on cars that do run cooled EGR.

For owners and workshops across Australia and New Zealand, that means there’s no EGR valve to replace or service on a stock 2016 Impreza 2.0i. If someone’s quoting for an “EGR clean” on this car, it’s worth a second look—chances are they’re mixing it up with other emissions components like the EVAP purge solenoid or general intake/throttle body cleaning.

Good preventative care still matters. To keep the FB20 happy, stick to quality engine oil at the right intervals (AVCS is oil-sensitive), use good fuel, and consider periodic throttle body and PCV checks if the car does lots of short trips. If in doubt, confirm by VIN against the factory service manual or dealer parts system—market variants exist, but a conventional, external EGR valve isn’t part of the standard 2016 Impreza 2.0i package.

Popular questions about 2016 Subaru Impreza EGR valves

Does my 2016 Subaru Impreza actually have an EGR valve?
For the 2.0-litre FB20-powered 2016 Impreza, no. Subaru’s service manual and parts catalogues don’t list an EGR valve on this model year, and Subaru’s later FB20D launch materials explicitly note cooled EGR was added for the 2017 model change, not earlier.

Why do I see “EGR” mentioned online for Subarus if mine doesn’t have one?
Different Subaru engines vary. Some later FB/FA engines (and diesel variants) use cooled EGR. Many forum threads mix models and years. On the 2016 Impreza 2.0i, emissions control relies on AVCS, catalytic converters and related systems—no external EGR valve to clean or replace.

What should be serviced instead if I was quoted for an EGR clean?
Ask the shop to clarify the component. Common maintenance on this engine includes throttle body cleaning, PCV valve checks, EVAP purge solenoid diagnostics, and keeping on top of oil changes to keep AVCS happy. Those deliver the reliability and drivability gains people often chase with “EGR cleaning” on other cars.
