Shop engine parts for the Subaru WRX 2015–2021 (VA chassis). The VA-chassis WRX is powered by the FA20F / FA20DIT 2.0-liter direct-injected, twin-scroll turbocharged flat-four (268 hp and 258 lb-ft in USDM trim), and this generation was sold as a standalone model with no hatchback offered. Because the FA20 uses direct injection only, fuel does not wash the intake valves, and carbon buildup on the valves is a documented VA engine-care topic. You will find internals, gaskets, engine mounts, pulleys, hardware here — every part in this collection is fitment-tagged for the 2015–2021 WRX, so check your trim, year and engine against the product fitment notes before ordering.
Every engine part in this collection is fitment-tagged for the VA-chassis WRX (2015–2021), which used the FA20F / FA20DIT 2.0-liter direct-injected turbo flat-four for the whole run. Check your year and trim against the product fitment notes, and confirm fitment on the product page before ordering.
The FA20DIT uses direct injection only, so fuel does not wash the intake valves the way it does in a port-injected engine, and carbon buildup on the intake valves is a documented VA owner topic. Walnut blasting is cited as a cleaning method, with independent buying coverage recommending it in roughly the 40,000–50,000 mile range, alongside attention to oil and fuel habits.
