Timothy ★★★★★

I was a bit worried about the install, but the included 1/8" venturi and install kit made it plug-and-play on my S550. My tuner said the fuel pressure is rock solid now, even with the extra boost.

Henry U. ★★★★★

The install kit that came with it had everything I needed, and the included venturi is a nice bonus. Fuel pressure is rock solid now, even under boost.

Sebastian ★★★★★

Dropped it in my S550 last weekend and the 415lph flow really woke up the car with the new injectors. The venturi setup was a nice surprise—keeps the bucket full even below a quarter tank.
