Add some horsepower to your 2015+ STI with the new Mishimoto Performance Air Intake. This kit is engineered specifically for your 2015+ Subaru STI and includes everything needed to replace the restrictive stock airbox. Their engineers spent months fine-tuning this design in an attempt to squeak out every last bit of performance. This dyno-proven air intake provides 20 whp/18 wtq gains over the stock intake while maintaining safe air/fuel ratios, perfect for some extra punch on the street or autocross course.

The Mishimoto Subaru 2015+ STI Performance Air Intake includes everything needed for installation, installs in under one hour, and works perfectly with the stock tune. The mandrel-bent aluminum intake pipe is available with a red or black powder-coated finish or a polished aluminum finish. This pipe utilizes the Mishimoto air straightener and CNC-machined mass airflow sensor (MAF) housing to provide accurate and consistent MAF readings, which translates into a smooth power band. To reduce air intake temperatures (IATs), the air filter has been placed outside the hot engine bay, and a powder-coated heat shield prevents any heat-soak from occurring. The Mishimoto free-flowing air filter provides a 16% greater surface area, optimal airflow, and proper filtration of dirt and debris. The included Mishimoto oiled air filter is completely serviceable, allowing for a lifetime of reliable use. Additionally this kit includes a silicone coupler, clamps, and all other hardware necessary to complete a quick installation for easy bolt-on power. A rubber cap is provided to place over the sound symposer housing. Along with an upgrade in power, this intake also provides an aggressive and rich intake tone that is a huge improvement over the stock intake. The Mishimoto Subaru WRX/STI Performance Air Intake is designed in Delaware, USA and includes the Mishimoto Lifetime Warranty.

  1. 2015+ doesn’t mean 2019

    By OkieSubie August 4, 2020

    Intake doesn’t fit 2019 STI. The filter runs into the chassis and wheel well. The shield fitment is hindered by the headlights. Will be requesting an exchange...hope they honor it as nowhere on the page it states it doesn’t work with a 2019.

  2. Amazing

    By Ryan May 7, 2019

    The sound coming from this intake is unbelievable. I could not be any more satisfied. Subiespeed got it to me in a short period of time with all required pieces. Just to put it in perspective, this intake has gotten me two tickets in a single day because I wanted to hear the sound of it. So beware. Lol

  3. Only good for 93+ Octane

    By MagicMan66 October 10, 2018

    I purchased this only to find out no tune is required only for 93+ Octane. I live in AZ and the highest we have is 91.

  4. A great upgrade for any Subi

    By Spencer September 17, 2017

    Overall extremely pleased with the upgrade. Fairly easy to install took ~30mins, the added sound factor is awesome. Only down on this one was the cabin sound cap was missing in my set. Subispeed did respond and help me get in touch with Mishimoto to get that replaced

  5. A must have Stage1 upgrade

    By Rob March 16, 2016

    Red crackle matches motor nicely, all direct fit and installs tightly, also too much - had to work it in after figuring out the dance of install steps. Kev made it look too easy! Didn't take but a few gear changes to love the new improved rush and sound. Sweeeet.
