Looking to feed your classic GC8 Impreza WRX or STI a little more fuel?

This set of four 440cc injectors from KSM Motorsports is exactly what you need for a solid performance upgrade or to replace tired old injectors.

They're designed for the EJ20 engine in the 1993-1998 models.

These aren't just pulled off a shelf – they've been ASNU tested and professionally flow-matched to guarantee they're within OEM specs and each flows exactly 440cc.

So you get smooth idle and reliable power.

They're a direct replacement for the stock injectors (OE number 16611-AA231) and come with new O-rings and seals.

Whether you're running a mild tune or just refreshing the engine, these are a great choice.

Works with petrol or ethanol blends.

KSM backs them with a 1-year warranty.
