Installing numerous different larger intakes over the years, we wanted to fix a lot of short comings we came across with other intake brands. 

We started our design by 3D scanning a factory intake and turbo inlet pipe. One of our main goals with this intake was fitment, and having the exact dimensions of the factory intake allowed us to engineer a better fitting and easier to install intake. The Damond Motorsports 3.5" intake features a tight-radius mandrel-bent 90° pipe going to the turbo. Using this pipe allows for a much better fitting and sealing intake-to-turbo connection, and makes the install much easier.

Keeping the intake lightweight was also a priority. We ditched the idea of a separate MAF housing and kept this all a 1-piece design. Less components means less weight, and less of a chance for leaks. We also omitted the BPV recirculation tube to reduce weight, reduce leak points, and make for an overall more compact and sleek design. 

For filtration, we utilize an American made, pre-oiled, and woven-cotton media filter which traps particles as small as 5 microns, and allows for more airflow compared to dry media filters. 

If you have a Mazdaspeed3 this intake will fit with the factory battery box with the ECU relocated or by modifying the battery box mounting holes. For the Mazdaspeed6, the battery tray can be modified to fit the intake. Optionally on both cars, a smaller battery and mount can be used to allow for more room.

We also include a new MAF o-ring with each intake.

Please note: MAF calibration and tuning is required. This is a non-recirc intake, where a blow-off-valve (BOV) is required. We offer a TurboSmart BOV here. May not fit with some FMIC hot piping.

This is the intake you are looking for

Hands down the only option you should consider. Went from a 2.5 inch to this and I'm literally blown away. Much better sound, spool, quality and fitment, coming from a silicone assembly. Don't even think about it, just add it to the cart


Love it! Great performance and looks awesome in my engine bay.

Fits beautifully

This intake fit on with zero issues. I do have the JBR battery box with the 51R battery. It seems well built, and looks great!! I expected nothing less from damond motorsports. Top notch!! Do not regret pushing that purchase button!

Fits like a glove

I was purchasing a bunch of new parts for my car and my tuner suggested this intake. I was a little nervous about fitment as I was changing out a bunch of parts at once and this was brand new on the market. There was no need to worry as this thing fits easily. I did relocate the ECU and had to do a little finessing with the cold side piping and BOV but it still fit like a glove. Overall I am super happy with the quality of the product as well as the professionalism of DM.
