Description
Fuel starvation during aggressive acceleration or high-G cornering can lean out your mixture and kill power when you need it most. Moroso’s Jet Extensions reposition your fuel jets deeper into the bowl, maintaining consistent fuel delivery under extreme driving conditions. If you’re running a Holley 4-barrel and pushing hard on the track or strip, this is a straightforward bolt-in solution to stabilize your fuel curve.
