AMS

The best AMS Performance parts for a 22-26 WRX are the AMS top mount intercooler, the AMS air intake with duct and airbox, and the AMS charge pipe for an aftermarket TMIC — together they address the three main bottlenecks of the FA24’s charge-air path: heat soak, intake restriction, and boost-pipe flow. Beyond the power path, the AMS carbon fiber weighted shift knob and stainless steel brake lines for 22-26 WRX MT models round out a well-sorted street build with sharper shifts and a firmer pedal.

AMS Performance builds engineered, no-shortcut parts for turbocharged platforms, and this collection centers on the 22-26 WRX. A top mount intercooler replaces the factory unit to resist heat soak during back-to-back pulls, while the intake kit’s included duct and airbox matter more than most shoppers realize: ducted, sealed airflow keeps intake temperatures down instead of pulling hot engine-bay air. The charge pipe is designed around an aftermarket TMIC, so check your current setup before ordering — it pairs with the AMS intercooler rather than the stock unit. Supporting pieces like the billet engine oil dipstick add under-hood refinement with a machined finish that holds up over time.

What sets AMS apart in this lineup is how deliberately the parts are designed as a system. The intake’s ducting and sealed airbox, the intercooler’s heat-soak resistance, and the charge pipe’s flow path are all aimed at the same goal: consistent, repeatable performance on a turbocharged car that gets driven hard. For a WRX that sees track days or spirited street driving, upgrading the charge-air path as a group typically delivers more consistent results than any single part on its own. Complementary AMS touches like the weighted shift knob (available for WRX/STI applications — confirm your year) improve the daily driving experience without touching the powertrain.

Will the AMS top mount intercooler fit my WRX?

The intercooler in this collection is listed for the 22-26 WRX. Always match the fitment tag on the product page against your model year before ordering, and confirm fitment notes for any charge pipe you pair it with.

Do I need a tune for an intake or intercooler?

Intake and intercooler upgrades can change measured airflow, so check with your tuner before installing. Requirements vary by part and by how aggressively the car is modified elsewhere.

Is the charge pipe a standalone upgrade?

The AMS charge pipe is listed for use with an aftermarket TMIC, not the stock intercooler. If you are still running the factory intercooler, the top mount intercooler and charge pipe make sense as a pair.

How difficult is installation?

Most parts in this collection are bolt-on with basic hand tools. A top mount intercooler or intake is a moderate driveway job; budget a few hours the first time and keep the factory hardware in case you ever revert.
