Best Cold Air Intakes for the 2015–2021 WRX: 4 Top Picks Compared
Four cold air intakes in our catalog genuinely fit the 2015–2021 WRX, and they split cleanly by budget: the Perrin cold air intake ($419.90) and ETS intake ($459.00) are the proven mid-range picks, the GrimmSpeed StealthBox ($558.00) is the engineered-airbox option, and the COBB Redline carbon fiber intake ($875.00) is the premium one. All four were verified active today — and as with any VA WRX intake, plan on the appropriate tune for your setup rather than treating any intake as a bolt-on-and-forget part.
1. Perrin Cold Air Intake, Black — $419.90
Perrin [15-21 WRX] Black Cold Air Intake — $419.90. The entry point of this guide. Perrin's listing covers the full 2015–2021 WRX run, and red and neon yellow finishes are listed at similar prices ($419.90–$439.45) if black is too subtle for your engine bay.
2. ETS Intake — $459.00
ETS [15-21 WRX] Intake — $459.00. ETS built its VA WRX reputation on intercoolers and exhausts, and its intake is the same philosophy: simple, well-made, and priced in the middle of the market.
3. GrimmSpeed StealthBox Cold Air Intake — $558.00
Grimmspeed [15-21 WRX] StealthBox Cold Air Intake Black / Red | 060060 — $558.00. The StealthBox is the pick for owners who want the intake sealed in an airbox rather than breathing engine-bay air — GrimmSpeed's listing covers the 2015–2021 WRX in black and red finishes. It is the most expensive of the three mid-range intakes here, and the airbox is what you are paying for.
4. COBB Redline Carbon Fiber Intake — $875.00
COBB [15-21 WRX] Redline Carbon Fiber Intake - Gloss Carbon Fiber — $875.00. The premium option: COBB's Redline intake in gloss carbon fiber for the 2015–2021 WRX. COBB is the natural pairing for Accessport-tuned cars, and the carbon construction makes this the one owners leave the hood open for at meets. (For contrast, COBB's Stage 1+ SF Intake Power Package is also listed at $1,180.00 if you want the intake bundled into a package.)
