Mishimoto MMAB-WRX-15 Airbox for 2015–2021 Subaru WRX

The Mishimoto MMAB-WRX-15 Airbox is designed to enhance both the performance and appearance of your existing Mishimoto Performance Air Intake. Finished in a clean black powdercoat, this steel airbox helps direct more cool outside air toward the intake, improving efficiency and offering more consistent airflow compared to an open intake setup.

In addition to improving airflow, this airbox can help provide more stable MAF readings — especially beneficial during tuning and datalogging. The durable construction, protective edge trim, and included mounting hardware ensure a clean and secure installation. With a simple bolt-on design and improved cold-air channeling, this airbox is a smart upgrade for any WRX running a Mishimoto intake.

As with all Mishimoto products, the MMAB-WRX-15 Airbox is backed by their industry-leading Lifetime Warranty.
