The AEM 21-807C fits some Infiniti Q50 models. See vehicle applications for details.
The AEM 21-807C is designed to replace the restrictive air filter and airbox of specific Infiniti Q50 models. 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 airbox, and uses the factory engine cover as it's top cover. To create a seal between the AEM heatshield/airbox and engine cover a rubber edge trim is included. The 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 21-807C vehicle applications to determine the legal status for each vehicle.
