Why Upgrade Your FK8 with the AEM 21-807C?
Because the K20C1 is a boost-hungry demon being force-fed through a glorified drinking straw.
The AEM 21-807C delivers:
-
Huge airflow improvement over the OEM intake
-
Faster turbo spool & reduced lag
-
Stronger mid-range and top-end pull
-
Aggressive turbo induction sound (you’ll hear spool, surge, flutter… all the good stuff)
-
AEM Dryflow oil-free filter
-
Sealed cold-air design to keep intake temps low
-
Mandrel-bent aluminum tube for maximum airflow efficiency
For the FK8, this is one of the highest-impact bolt-ons before tuning.
The AEM 21-807C is designed to replace the restrictive air filter and air box of specific Infiniti Q50 models.
Key Features of the AEM 21-807C Cold Air Intake
🌀 Mandrel-Bent Aluminum Intake Tube
Built specifically to maintain correct MAF readings for the K20C1—no tuning required.
The oversized oval-shaped AEM Dry Flow filter is made from an oil-free, synthetic filter media and can be used for up to 100,000 miles before cleaning is needed (depending on driving conditions).

The AEM heatshield replaces the restrictive factory air box, and uses the factory engine cover as it’s top cover.

Uses factory mounting points
-
Proper sensor locations

Clean FK8 engine bay fit
To create a seal between the AEM heatshield/air box and engine cover a rubber edge trim is included.
🎧 Turbo Sound Enhancement
The “angry spaceship” soundtrack Honda tried to hide? Unlocked.
The air intake system is backed by AEM. 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 21-807C vehicle applications to determine the legal status for each vehicle.
