Default Mishimoto Build Thread: Subaru WRX/STi Engine Bay Accessories

Hey guys,

Our team recently developed a few engine bay components to help improve the aesthetics of your Subaru. Check out our writeup on the blog or in this thread!

http://engineering.mishimoto.com/?cat=183

Mishimoto 2015 Subaru WRX Engine Bay Dress-up Components, Part 1: Battery Tie-Down

Mishimoto is not only interested in improving the performance, reliability, and power output of your new Subaru, but we also care about aesthetics. Small touches in the engine bay can make a big impact on the overall appearance and also provide a sense of personalization. Our first targeted component is the battery tie-down. The stock tie-down is rather bland, its main purpose being functionality, which is fine for a stock unit. For those looking to upgrade, a stylish aluminum replacement is ideal. In case you haven’t yet peered into the engine bay of your ‘15, here is what the stock tie-down looks like.

Our first task was to design a few prototypes and see what design we thought was most appealing. This is much easier said than done. Check out a few renderings of the design ideas from our team.

Once we had our initial designs modeled in 3D, we printed them using our 3D printer. The 3D prototypes would help our team evaluate each design and visualize them on the vehicle. Once again, this 3D printer has been an invaluable tool for our engineering group, by quickly providing prototypes that have helped to speed up our processes for bringing components to market. Check out our first design!

And our second design!

Now, it is quite a challenge to develop an aesthetic product that satisfies everyone. Our goal was to provide a unique, yet subtle design. To do so, we surveyed our entire office staff for their opinions and recommendations for each design. The result was a split decision, and we ended up designing a product that has design elements pulled from each of our initial ideas. Check out the drawing below for the final design!

Once our design was fully modeled, we worked up a few initial raw prototypes.

After confirming that these prototypes fit perfectly, we began mass production of the tie-downs in the anodized colors listed below. Our hope is that these colors will appeal to all who are interested in this component. If you have an additional recommendation, let us know and we can add it to the list.
  • Black
  • Blue
  • Red
  • Gray
  • Gold
  • Pink
Before we conclude this write-up, take a sneak peak of the Mishimoto Subaru Battery Tie-Down in fully finished, anodized form.

Thanks for reading! Check back with us next time for an overview of the development of our 2015 Subaru WRX aluminum radiator stays!

Thanks!

Check out the process of designing our radiator stays in the second post for this build!

Mishimoto 2015 Subaru WRX Engine Bay Dress-up Components, Part 2: Radiator Stays

Now that we had our battery tie-down finalized, we could focus on the next component we wanted to tackle in the engine bay. Our next target would be the radiator stays, the small stamped steel pieces holding the radiator to the radiator support. We offer anodized aluminum radiator stays for a variety of vehicles including the previous generation WRX/STI, Honda Civic, and Ford Mustang. An example of what we have developed in the past is shown below.

For this particular project, we would be following a similar route. Our stays would be produced in aluminum and then anodized in a variety of colors to match an engine bay accent color. Before we get into the Mishimoto design, take a look at the stock components.

Following our standard product development procedure for smaller components, we designed our stays in Solidworks and printed them using our 3D printer. This process provides a real-world piece that we can test-fit on the vehicle to ensure perfect fitment. It also lets us see the item and how it looks aesthetically before we begin the workup of an aluminum prototype. Check out our printed design!

Once we confirmed fitment and made a few minor adjustments, as seen in the first image, we worked up an aluminum prototype to compare the two. Check it out below!

Check out a few shots of our aluminum prototype stays by themselves!

We then bolted these prototype units into position on a vehicle to confirm fitment.

And finally, a cool shot of the SolidWorks drawing of this component.

Now that the project was complete, we could move into mass production of these radiator stays. As with our battery tie-down, we will be offering these in a variety of colors including black, blue, red, and gray. To put a final close on this project, check out the anodized, final version of the Mishimoto radiator stays!

Thanks for following along with the progress of our engine bay dress-up projects, and keep an eye out for the official release of these awesome products!

Thanks!
