StealthBox Cold Air Intake - Black

• 2018 Subaru | WRX STI Type RA
• 2015–2021 Subaru | WRX STI

The GrimmSpeed StealthBox Cold Air Intake (060077, Black) for the 2015-2021 Subaru WRX STI is a hybrid of the tube and filter used in its 08-14 WRX intake and the StealthBox heat shield used in its 2015+ WRX intake. Small design changes were made, but the overall fit and performance are approximately the same.

Tuning required: not compatible with the factory tune or any off-the-shelf maps.

Quick specs

• Hybrid cold air/short ram design, combining the advantages and eliminating the negatives of both
• Air straightener dimensionally mimics the factory configuration for accurate MAF readings
• MAF sensor located inside the heat shield, isolated from engine bay heat
• Custom reusable high-flow air filter with integrated velocity stack entrance
• StealthBox heat shield keeps engine bay heat from affecting performance
• Made in the USA
• 30-minute installation with written and video guides

Why GrimmSpeed

These intakes feature the proven performance of its 08-14 WRX EJ intake (third-party results coming soon) with a look and feel that sets them apart, and that with the StealthBox heat shield you no longer need a shoe box hanging out where the factory airbox used to be.
