Boost Reference Adapter Mazda 3 Turbo

Looking to add a boost gauge to your SkyActiv 2.5L Turbo Mazda so you can monitor boost levels while driving? If that’s the case then the CorkSport Boost Reference Adapter will help simplify the install process and requires no permanent modification.

The CS Boost Adapter allows you access to the same port in the intake manifold that the MAP sensor utilizes. This makes it so installation is as easy as removing a screw and placing the adapter between the MAP sensor and the intake manifold, and just like that, you have access to a boost source via a 3/16 in-barb.

Mazda 3 Performance Manifold Pressure Gauge

Fitment and Design:

The CorkSport Boost Reference Adapter is designed to offer an additional port in the intake manifold without making any permanent modifications.

The adapter acts as a spacer for the MAP sensor so that a 1/8 NPT fitting with a 3/16 inch barb can be installed.

This fitting allows you to connect your boost gauge directly to the manifold so you get accurate boost readings that are post-intercooler.

Material and Hardware:

For the CS Boost Adapter, 6061-T6 aluminum was selected for its good corrosion resistance and machinability. This part gets CNC machined out of the billet to provide tight tolerances and is anodized black.

Also included with the CorkSport Boost Reference Adapter is a new stainless steel screw that secures the adapter and MAP sensor to the intake manifold.

Hose is not included with the Boost Reference Adapter Kit.
MAP Sensor is not included with the Boost Reference Adapter Kit, only shown for reference.

I used this on my 3rd gen and it worked great. Plumbed some clear hose to it and ran it through my firewall. Vacuum gauge now works! Much better solution than having to cut a hose somewhere on the car. Definitely recommend.

Super easy and simple install! Probably the easiest install I’ve ever done on my car. Saved me a lot of time with boost gauge install.

Any reason this wouldn't work for the supercharger kit as well? The kit has a hose barb installed on the supercharger already, above the thottlebody somewhat, but it'd be nice to relocate the hose to route under everything as I already feel like I am looking at a bowl of spaghetti with all the hoses on top.
