The BTR Equalizer 1 is a cathedral-port, multi-port intake manifold built for small block Chevy combinations targeting peak power between 6000 and 8000 rpm. Per BTR, boosted combinations are actually more consistent making peak power in this higher range than most stock-style intakes that peak around 6500 rpm, provided the valvetrain is built to support it. It's cast from 319 aluminum, powder coated black, and designed and made in the USA, with a 2-piece design that leaves the ports open for further porting work.
