AEM 19-20 Mazda 3 2.5L L4 Cold Air Intake - 21-877C
$419.99
This Performance Air Intake System allows your engine to breathe more air compared to the restrictive factory air intake housing. It is designed, tuned and dyno-tested to produce more horsepower and torque. Air enters the system through an oversized AEM Dryflow synthetic washable air filter for outstanding air flow, filtration and performance. The air intake tube is constructed from mandrel-bent aluminum featuring a durable gunmetal gray powder coated finish. A custom shaped heat shield with lid is included. The tapered cylinder shaped AEM Dryflow air filter is made from an oil-free, synthetic filter media that can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions). This Air Intake System is backed by AEM's Lifetime Limited Warranty. Some AEM air intakes are not legal for sale or use in California and other states adopting California emission standards, while others are 50 state legal. View the vehicle applications to determine the legal status for each vehicle.

No — this part has no CARB Executive Order, so it is not for sale or use in California or on vehicles registered there.
The maker's installation guide is on this page — see Installation guide under the part details for the step-by-step and the torque figures. Work on level ground with the car properly supported, and torque every fastener to the maker's figure. If the job is beyond your tools, any shop that does this kind of work can fit it.
Most intakes work with the stock tune. When an intake changes the sensor housing size, the maker says a tune is required.
Follow the maker's service interval. Dry filters are blown out or washed; oiled filters are washed and re-oiled with the maker's kit. Over-oiling can foul the airflow sensor.
Yes. Most intakes make the induction sound louder, especially at wide throttle.
Yes. An intake is usually a bolt-on job with hand tools; the maker's guide covers the clamps and the sensor move.
A full intake kit includes its filter; a replacement filter is sold on its own. See What's in the box above.
Yes — monthly options show right under the Add to Cart button. Affirm, Klarna, PayPal Pay Later and Snap Finance are offered at checkout, and checking what you qualify for does not affect your credit score.
Install and care: cold air intake
Before you start
- Read the maker's guide for where the airflow sensor moves to.
- Have the clamps and hand tools the guide names within reach.
Do
- Seat every coupler fully and tighten the clamps evenly.
- Service the filter on the maker's interval and use the maker's cleaning kit.
Don't
- Don't over-oil an oiled filter; it fouls the airflow sensor.
- Don't run the engine with a coupler loose.
