2022+ Honda Civic SI Aftermarket & Performance Parts

The best parts for a 2022+ Honda Civic Si are the upgrades that sharpen what the car already does well: a freer-flowing cat-back exhaust for sound, a cold air intake for the 1.5T engine, and coilovers or lowering springs that reduce body roll without ruining the daily drive. This collection gathers those proven first steps for the 11th generation Si, so check your year and model before ordering.

The Si in this range is the FE1 sedan, and most products here are built specifically for the 2022-2026 window, with several also fitting the related Acura Integra. Exhausts, intakes, clutches, brakes, and suspension all appear because they are the areas Si owners modify first. Start with the part that matches your goal and build in stages.

Brands in This Collection

Remark leads the exhaust options with its Link Loop cat-back for the 22-26 Civic Si, offered with a stainless steel tip or a burnt stainless tip. That single design choice sums up Remark's appeal here: a model-specific system where the visible finish is part of the decision. The Link Loop cat-back with stainless tip is the clean, understated version of the same idea.

AWE Tuning offers the alternative exhaust philosophy: two distinct editions for the same car. Its Track Edition dual exhaust is the louder, less filtered choice, while the Touring Edition aims for a more refined daily tone, and both also fit the 23-26 Integra. Choosing between them is really choosing how much volume you want to live with every day.

PRL Motorsports handles airflow with the Cobra Cold Air Intake System for the 22-26 Civic Si 1.5T, a model-specific intake rather than a universal filter on a tube. PRL's presence across Honda turbo platforms makes it a familiar first intake choice for this chassis. See the Cobra intake listing for its exact fitment notes.

For handling, Silver's North America supplies the NEOMAX coilover kit for the 22+ FE1, while Eibach's Pro-Kit covers the simpler lowering-spring route. On the drivetrain side, ACT and Exedy both appear with clutches for this car, and COBB Tuning offers its Accessport V3 for the FE1, giving the collection a tuning path as well as hardware. Browse the wider Civic Si range for earlier generations, and read our top 3 parts for the Civic Si for a staged starting point. One handling example here is the Silver's NEOMAX coilover kit.

Frequently Asked Questions

Do these parts fit the Acura Integra too?

Some do: the AWE exhausts and the ACT clutch list Integra fitment alongside the Civic Si. Others are Si-only, so check your year and model on each listing before ordering.

Does a cold air intake require a tune on the 1.5T Si?

Intake changes alter airflow readings, and tuning is commonly recommended to get the full benefit and keep fueling correct. Follow the intake maker's guidance for the FE1 and plan accordingly.

Track or Touring exhaust for a daily driver?

Touring-style systems are voiced for everyday use, while Track editions are louder by design. If the car commutes daily, the touring direction is usually the easier one to live with.

Are coilovers a difficult install?

Coilovers are a moderate install with hand tools, but the car needs an alignment afterward. Springs alone are cheaper, while coilovers add height and damping adjustment.
