    No One Likes a Leaking Cap - Washer Fluid Reservoir R&D, Part 2: Improving on OEM

    When we began work on our 2016+ Miata washer fluid reservoir, our primary goal was to improve the aesthetics; we designed the tank to look killer, make your engine bay a little cleaner, and we also reduced the volume of the reservoir, saving a few pounds versus stock if you're comparing a full Mishimoto tank to a full stock tank.

    One of the major benefits of sharing our R&D process among enthusiast communities is the opportunity to learn even more about what we can do to make the best possible product. Once I revealed our reservoir to the forums, I was quickly made aware that there is an annoying flaw with the stock tank: a leaking cap!

    Subaru WRX/STi Performance Cold-Air Intake

    With our initial designs complete and fully assembled, the engineers were ready for testing. We strapped our STI to the dyno and began making some initial pulls with the car completely stock and using the OEM intake. We were averaging upper 250s to lower 260s at the wheels, which was what we expected from this car. After having some fun we removed the factory intake system, including the airbox, air induction tube, and MAF housing. We bolted on our first design and made a few pulls. We found that the air/fuel ratio (AFR) was a bit on the lean side for our tastes, so after a few runs we decided to call it quits for the day and reevaluate this design. Bolting on the second design provided slightly improved AFRs, but they were still at a point where we were

    Subaru WRX/STi Performance Cold-Air Intake

    Here we are at round two of product development. The shear, brake, and welder had quite a workout as our team set to work on developing two very different prototypes for testing.

    The first design was rather unique and emulated the factory system quite well. This large, box design used a standard panel filter and pulled cold air from the fender/wheel-well area. This unit was very well designed and would keep your engine bay appearing OEM while providing improved power and tone. The design used a large box of undecided material for construction (aluminum vs. plastic) and a short length of piping to house the mass airflow sensor (MAF). While this unit was under construction, a new design was also explored. This one used aluminum intake piping off the
