850cc - GR Yaris/GR Corolla

The 850cc matched set transformed how my GR Corolla pulls through the mid-range, and the direct vehicle-specific fitment meant zero guesswork during installation. After a few hard drives, the response is noticeably crisper and more consistent at higher RPMs.

The plug-and-play design made installation straightforward, and the 850cc flow rate is exactly what my tuned GR Yaris needed. These injectors cleaned up my fuel trims nicely during the first few pulls.

Took my GR Corolla to the dyno after swapping these in and the air-fuel ratios stayed dead-on consistent across the whole pull. The matched set made installation straightforward, though I did have to double-check the fuel rail clips before seating them.
