Best Top-Mount Intercoolers for the 2022–2026 WRX: 5 Top Picks Compared

The best top-mount intercooler for a 2022–2026 WRX is a larger, more efficient core that keeps intake temperatures down on repeated pulls — the AMS Performance TMIC ($749.95) is our value pick with a core its listing puts at 71% larger than stock, while the ETS TMIC ($895) brings the biggest charge-row count here. All five intercoolers below are listed for the 2022–2026 WRX, and we finish with our own JDMuscle mesh guard ($149) — the protection pick for owners keeping the stock core, because it fits the OEM TMIC only.

The VB WRX's FA24 turbo engine makes its power through a top-mount intercooler fed by the hood scoop. The stock core does the job at stock power, but heat soak is the enemy of consistency: back-to-back pulls, hot days, and tuned cars all push intake temps up and power down. A quality TMIC is the simplest fix because it stays in the factory location, keeps the factory ducting concept, and does not require cutting the front of the car the way a front-mount does. Here is how the five we sell stack up.

1. AMS Performance [22-26 WRX] Top Mount Intercooler — $749.95

The AMS Performance Top Mount Intercooler is the strongest value on this list. Per its listing, the bar-and-plate core measures 21" x 7.5" x 4" and is 71% larger than the factory core, with cast aluminum end tanks and TIG-welded construction. AMS built its name on turbocharged platforms, and at $749.95 this is the least expensive full TMIC here — the obvious starting point for a tuned street car.

2. Mishimoto [22-26 WRX] Top-Mount Intercooler — Silver — $789.95

The Mishimoto Top-Mount Intercooler in Silver is the household-name option, listed for the 2022–2026 WRX at $789.95, with a black version at the same price if silver is not your engine bay's color scheme. Mishimoto's listing is light on published core dimensions, so check the product page for the latest specs before ordering — but as a brand with a long WRX catalog behind it, this is the familiar, well-supported choice at a mid-pack price.

3. ETS [22-26 WRX] Top Mount Intercooler — $895

The ETS Top Mount Intercooler is the maximum-core pick. Its listing describes a 21" x 7" x 4" core with 34 charge rows, a staggered fin design, billet inlet and outlet, and TIG-welded construction, and notes that it works with the factory charge pipe as a direct replacement. If your build plan includes a bigger turbo later, buying the most cooling you can fit under the scoop now is cheaper than buying an intercooler twice.

4. Perrin [22-26 WRX] Top Mount Intercooler — Black — $958.80

The Perrin Top Mount Intercooler in Black brings Perrin's long Subaru history to the VB. It is listed for the 2022–2026 WRX (the same listing also covers turbo Legacy and Outback models, so double-check the fitment notes for your exact car) at $958.80. The black finish keeps the engine bay understated, and Perrin also sells matching TMIC brackets in several colors if you want the install to look intentional rather than incidental.

5. COBB Tuning [22-26 WRX] Top Mount Intercooler Kit — Black — $1,155

The COBB Top Mount Intercooler Kit is the premium, ecosystem pick at $1,155, also available in silver at the same price. If your VB already runs COBB tuning and parts, this is the TMIC designed to live in that ecosystem, sold as a complete kit rather than a bare core. You pay more than for the AMS or Mishimoto, and what you are buying is the integrated, single-brand path.

Protect the core: JDMuscle TMIC Mesh Guard — $149

If you are keeping the stock core, its fins face the hood scoop — and everything the scoop swallows. Our own JDMuscle Top Mount Intercooler Mesh Guard ($149) sits over the core to deflect rocks and road debris before they flatten fins, and it carries a WRX/STI logo in red/white. It is listed for the 2022–2026 WRX, plus 2019+ Ascent and 2020+ Outback and Legacy turbo models. One thing to know before you order: the guard fits the OEM TMIC only — it does not fit the larger aftermarket cores above. On a stock-core car, $149 of mesh is cheap insurance against fin damage.

Quick comparison

How to choose

Match the core to your power goals. A stock or lightly tuned street car is well served by the AMS or Mishimoto. Cars headed for bigger turbos and higher boost should buy headroom now — that is the ETS case.

Top-mount or front-mount? A TMIC keeps the factory location, short piping, and throttle response, and needs no bumper cutting. A front-mount offers more total core area for extreme builds but adds piping length and install work. For most VB street and weekend-track cars, a good TMIC is the right answer.

Budget for protection and a tune check. On the stock core, add the mesh guard (OEM TMIC fitment only) while the fins are still clean, and if your car is tuned, confirm with your tuner whether your current map is happy with the new core's pressure and temperature behavior.

Bottom line: start with the AMS TMIC for value, step up to the ETS for maximum cooling headroom — and if your build keeps the stock core instead, protect it with a JDMuscle mesh guard (OEM TMIC fitment only).
