So I give no kudos to Grimspeed and have no disdain for Mishimoto.

Its a freaking airbox for a tiny little engine. Hell the damn filter and box are in the same freaking place as stock. There is no new air intake and no new special sauce other than some nice looking housings and a cone filter.

How much air do you think a 2.0 liter 4 banger needs? If this engine was starved for air then maybe some of these aftermarket intakes would do some real meaningful hp gains. Thing is adding more air to an engine that already has plenty does not really do any good.

Sorry you feel this way! As noted in our thread, each of our products undergoes rigorous testing and none of our results are skewed in any way. The plots from our cold-air system are an average of 3 consistent runs (for both stock and Mishimoto). We tested multiple MAF housing diameters which impacts AFRs. The combination of a scaled MAF and improved flow are definitely contributors to producing greater power output. This is shown in our development coverage below.

We did not make 10 whp from 3,000 rpm to redline but we did make power through a majority of the powerband and our 10whp/8 wtq maximum gains were achieved close to redline.

We are using the same diameter MAF housing with our new V2 system and it will be interesting to see if our results are similar with the new filter location.

Thanks

Project update! Check it out below.

A New Mishimoto BRZ/FR-S Intake, Part 2: Box Fabrication and 3D Prototype

We left off last time with an explanation of our intentions with this intake system and some initial design work to create an induction route to our planned airbox. Now it was time to finish designing this intake system so that testing could be conducted.

Airbox Fabrication

We started developing our airbox with simple metal fabrication. The plan was to put our idea into a physical object and then transfer this to a 3D model. Once in Solidworks, we could solidify the final design and features and use our 3D printer to construct a final prototype for test fitting.

Fabrication begins! A simple box was drawn up and templates printed for our bends and mounting point locations.

Bends were made, holes were drilled, and here is what we ended up with.

We then constructed a lid to contain airflow coming in through the scoop and to reduce the impact of engine bay heat-soak.


Airbox lid fabrication

As noted in our first portion of this series, we wanted to ensure that out airbox would function with our oil sandwich plate and oil cooler kit. A few aftermarket intake systems are not compatible because they occupy the same space as the fittings we attach to the plate. Check out the clearance shot with our airbox!

We then finished off the base of the airbox and ended up with our first completed prototype. Check out a few images of this!

As you can see, we are using rubber weather-stripping around all the edges. This provides a factory-like appearance and reduces any chances of noise created from vibrating components.

Below is the lid for the box. This prototype unit is void of any mounting points. We will be adding holes to accommodate our mounting hardware.

And our final assembled prototype!

3D Prototype

After completing our fabricated prototype, we set our engineering team to work modeling this box in Solidworks. A few small tweaks and adjustments were made to the design as well. Once we had this complete, we decided to experiment a bit more with our new 3D printer. Printing this airbox was indeed within the constraints of the engine bay size, so we set up the printer and went home for the evening.

In the morning, we were pleasantly surprised with this!

Keep in mind some of the support material still needs to be removed from this printed box. Other than that, this turned out great!

We then installed this prototype in our test vehicle to ensure proper fitment!

With a solid design in place, it was time to test this setup to see what kind of gains we could achieve in terms of power output.

Check back next time for a look at our testing process, results, and a video from our dyno pulls!

Mishimoto: what do you think of fixing cover in place with something like sport hood pins for sake of style?

Interesting idea! I believe we are currently planning to utilize a black socket head bolt with a washer to prevent damage to the lid. I will certainly pass on the recommendation.

Looks good, can't wait to see dyno results. Any idea of color options on the intake pipe? Or will they all be red? Rough estimate on price when it's said and done?

Is your intake tube compatible with your 1st cold intake system? I recently order your intake tube because I thought it has more potential compare to Perrins intake tube like installing the reservoir from the stock intake sound tube for example. Just for future reference when I come around to stop using the stock intake and go with a full cold intake system. Thanks

Just curious if any thought had been given to re-shaping the shape of the intake box as follows (see blue line below):



Some of us with oil coolers have been looking for an intake box that:

1) Leaves plenty of space to run oil cooler lines/fittings near the oil filter
2) Allows the filter to be served through the engine bay
3) Draws cool air using the factory duct

I'm not an engineer, but reducing the volume of the airbox as shown above would probably prevent air from collecting in that empty space and be warmed up by ambient heat from the oil filter (and oil cooler lines).

Just some thoughts, not a critique of your design at all.

You'll have to wait for Grimmspeed's revision first so they can get a hold of it and copy it down to the perfect bend, weather stripping, and screw placement.

I have the Grimmspeed intake so I'm not likely to change (I did run your intake pipe prior to going to the Grimmspeed), but I wanted to offer a bit of advice based on my experience with their setup. Because of the flexible box material (aluminum) getting the lid in place and the screws on can be a challenge. If you could do studs on the box that the lid slips over and then nuts (heck you could use thumbscrews/wingnuts) to hold it in place, that would be much easier to install. Now, that said, I know that's going to be more expensive to assemble. But boy it would be more user friendly.

Thanks! The silicone intake hose portion will be available in black, blue and red.

Pricing details are not yet finalized on this intake system. We should have a concrete idea in regards to pricing and presale information early next week.

Thanks for the interest!

Unfortunately not! The intake hose in this particular kit utilizes a different angle where it meets the airbox. The two components will not be compatible. Sorry!

Thanks for the input and recommendation! Box volume was certainly considered during the design of this intake. We wanted to ensure air volume was sufficient for transitions from part throttle to full throttle when large amounts of air are pulled from the area surrounding the filter. Because of this, we made the box as large as possible within the constraints of fitting with our oil cooler sandwich plate and all OEM components in the engine bay. This particular volume will have no issue supporting the needs of stock and modified examples operating at full throttle.

Thanks!

Got it! We appreciate the feedback here. I believe we are currently going with socket cap bolts on this particular kit. Our box is constructed from powder coated steel so it should have a bit more rigidity than an aluminum unit, meaning the flex should not inhibit installation to a great degree.

We will certainly keep this in mind if we get any reports of issues with flex!

Thanks

Mishimoto: hmm .. socketbolts .. what do you think of thumbnuts so that they can be bolted in place with hands only? Or if anything else, then with sizes that match tools that are in standard kit in the boot of car? So that car owner will have anything needed for the job of replacing filter right away.
