Another Intake?

Wait " Mishimoto already has an intake for the BRZ/FR-S. Why design a second one? As this question crosses your mind, we can provide a simple explanation.

We have had great success with our existing cold-air intake system for this chassis, and the feedback from our customer base has been fantastic.

After listening to our customers both directly and through web forums, we concluded that a second intake design was necessary for a completely different set of customers. Here are a few plans for our new design.

• Engine-bay mounted, stock-appearing airbox setup
• Easy installation and filter servicing
• Fits with Mishimoto

As noted earlier in this article series, we would be tackling a race intake system to go along with our bolt-on unit. So what makes the race system different? For this particular system we are using a larger-diameter intake pipe with a larger MAF housing. This means greater intake flow, but it also means it will no longer function with the factory tune. This system is meant specifically for drivers who want aggressive professional tunes so they can take advantage of airflow modifications such as larger turbochargers and high boost pressures.

Because the 15' model shares the EJ from the previous generation, we would be using the same intake pipe and filter as we did with our 2008-2014 kit. This unit is shown below.

So, all we truly needed

Dyno Testing

Time to see what kind of power gains we are able to achieve with our intake design! First, we strapped this Launch Edition to the dynamometer.

Prototype Fabrication

After experimenting with some boxed designs in Part 1 of this write-up, it was time to turn our attention to a shrouded setup, similar to what we offer for the 2008-2014 models. We're hoping we could utilize the piping from our existing kit, which is well designed and has proven power gains. After placing the shroud into position, we found that it would certainly fit, but would require some modification. The fabrication work began! Check out a few shots taken during the process.

Introduction

Our team is finally working on some cool components for the new 2015 Subaru STI! As you know, the 2015 STI is essentially a hybrid of old and new Impreza components. It features the newer body style paired with the trusty EJ engine, instead of the new DIT motor featured in the WRX. We won't get into which is better or which we prefer, because we have nothing but praise for the updated chassis.

Mishimoto Silicone Induction Hose For Subaru BRZ / Scion FR-S

Thanks for returning for the second portion of this build! As mentioned in the previous post, our team was prepared to conduct extensive testing on this induction hose. Our main goal with testing was to determine the particular combination of components that would provide the most power output. Power output collection would be via our Dynojet. Each combination of components received an average output based on three consecutive runs all completed on the same day with essentially similar conditions. The variations of testing are below.

1. Resonator and noise amplifier both installed
2. Resonator plugged with noise amplifier installed
3. Resonator attached with noise amplifier disabled
4. Resonator and noise amplifier

Mishimoto Silicone Induction Hose For Subaru BRZ / Scion FR-S

The BRZ/FR-S is one of the hottest cars to hit the track in the past few years, and the Mishimoto engineers decided to do what they do best: cool it down. Naturally, we would be developing a performance aluminum radiator and silicone hose kit. Additionally we ended up with a killer direct-fit oil cooler kit, some very slick oil caps, and a low-temperature thermostat. As you may have seen in our other build-log, we are also developing a performance cold air intake, which we estimate will provide a nice increase in power and really bring out some of the engine tones being baffled by the factory system. This article is not about the full intake system we have planned. It's about the silicone induction hose we developed in the mix with all the products

Mishimoto Subaru BRZ / Scion FR-S Performance Cold-Air Intake

We know you've been dying to know how we finish up creating a cold-air intake, and today is the day you can breathe a sigh of relief. We are finally at the last stage of R&D! After constructing a final prototype we were prepared to test fitment and ensure that power output and AFR readings remained unchanged. Check out our final prototype components!
