I picked up this Corksport fuel rail kit for my V2 intake manifold so I could start my PI system . I just needed to drill out the holes in the manifold for the injectors, it came with all the hardware to fit my injector dynamics flawlessly and looks simple and clean in the engine bay . Stainless hardware compliments the valve cover dress up kit I got installed and love how it all ties together perfectly .

Hi, I mazdaspeed, and you can Mazdaspeed too! Best price and Awesome Performance. Not only does it improve flow and will allow you to run the same power of less boost, it will help save your precious CYL 3 from the abuse of un-equal air flow across the head. This thing is almost as necessary as upgraded HPFP internals. Getchu some!

Absolutely love this intake manifold. Install was less of a pain than an OEM PnP manifold. Works flawlessly with Corksports throttle body. Dropped my LTFT from 16.x down to .7!

Car feels amazing after the installation. The acceleration is so much better and a very noticeable difference. Highly recommend this to any Mazdaspeed owner.
Instructions are great and an easy install.

I beta tested this manifold on a built motor, ported head with a 6266 spraying methanol. Install was a breeze and the power came on quick and the power held until my redline of 7600rpms. Great flow and great look. Solid quality piece!

Sean Strout04/02/2018, 08:43 AM

Even flow and a lot of it. My car picked up 14 g/s on the same map with no changes. Fitment on this piece is outstanding - it's easier to install than the OEM and clearance blows away the competition. It has a slew of vacuum and meth bungs, making this perfect for someone wanting ~550 wheel horsepower (that's about the limit of the typical methanol pump). A knife edge PI spacer would be a great option for those wanting even more fuel and crazy boost.
