Non-Fuel Rail Version (drill if needed but this is undrilled)
 
These are really hard to come by and always sell out fast. The CorkSport V2 intake manifold is a serious upgrade for the DISI-MZR platform, built to improve airflow, power delivery, and cylinder-to-cylinder balance while still fitting like OE. This is the non fuel rail version, perfect if you want the manifold now and may add port injection later
 
This manifold also supports serious future growth. It has 1/8-27 NPT ports on each runner for methanol nozzles or other fueling options, and it includes provisions for port injection if you decide to upgrade later. Since this version is the non fuel rail model, it does not include the optional fuel rail kit.
 
The throttle body opening is 70mm compared with the OE 60mm opening, and the manifold is built from A356-T6 aluminum and machined for OE-style fitment. CorkSport also notes faster turbo response, with testing showing roughly 100 RPM quicker spool than OE, plus proven results up to 684whp on a built Mazdaspeed 3.
