Alexander ★★★★★ Oct 20, 2026

Bolted these in after watching a quick video, and the consistent 550cc flow made tuning my Apex noticeably smoother. Idle settled right where I wanted it without any tweaking.

Sofia ★★★★★ Oct 18, 2026

Plugged these into my 2007 Apex and the consistent 550cc flow rate made a noticeable difference in throttle response. They fired right up with no leaks, exactly what I needed for the rebuild.

Grace ★★★★☆ Oct 22, 2026

Pulled the stock injectors out and these 550cc units dropped right in on my 2008 Apex. Idles smooth and the consistent flow rate is exactly what I needed for my setup. Only knock is the price feels a bit steep for what you get.
