The Mazworx S13 SR20DET Intake Manifold not only keeps the low end torque of the OEM manifold, but also carries the torque and horsepower through the RPM range. This back-to-back testing was done on Kelsey Rowlings old SR20DET drift setup with a GTX3071R @ 17psi. The green lines are the OEM intake while the purple lines are the Mazworx intake.
Comes with a billet one piece runner section. This manifold comes with 4 injector pockets and a single fuel rail. Pick your throttle body flange based on your throttle body. Comes standard with the S13 IACV unless you select DBW TB, then no IACV is installed.
Fits 14mm x 48mm injectors.
Anodizing will color the complete inside and outside of the manifold black.
Here's a comparison of this intake manifold to an OEM one. Photo courteous of RS Enthalpy. Facebook link:
