Revitalize Your Drive: Cold Air Intake for Nissan Altima 2.5L

Give your 4-cylinder the breath it needs. The factory air box on your 2002-2006 Nissan Altima is designed for quiet operation, not performance. This restriction chokes your 2.5L engine, limiting its potential. Our Cold Air Intake Kit opens up the airways, delivering a high volume of cool, oxygen-rich air directly to the engine. The result? More horsepower, sharper acceleration, and a deep, throaty intake tone that makes your daily commute far more exciting.

Why Swap Your Factory Air Box?

• More Horsepower: Air is fuel. By increasing the volume of air available during the combustion cycle, this intake directly improves your engine's output and overall performance.
• Increased Acceleration: Reduce the restriction and reduce the lag. Enjoy snappier throttle response when merging onto highways or accelerating from a stop.
• Enhanced Sound: replace the silent factory hum with a deep, aggressive induction growl that sounds powerful when you step on the gas.
• Improved Gas Mileage: A more efficient engine doesn't just run faster; it runs smarter. Improved airflow can lead to better fuel economy during normal driving conditions.
• Save Money on Filters: This kit includes a high-performance air filter that is washable and reusable. Stop throwing money away on disposable paper filters—simply clean, dry, and reuse.
