Injen 04-10 QX56 / 04-12 Armada/Titan V8 5.6L w/Power Box Polished Power-Flow Air Intake System

If you're looking to get more out of your 2004-2015 Nissan Titan, Infiniti QX56, or Nissan Armada, especially when towing or under heavy load, this Injen Power-Flow air intake system is designed to help. This kit replaces your restrictive factory air intake with smooth, polished 6061-T6 aluminum tubing and a high-flow air filter, allowing your 5.6L V8 engine to breathe easier. The result is an improved engine tone and, as dyno testing shows, a significant boost in horsepower and torque.

Injen has engineered this system with their patented MR Technology, which tunes the intake tract to optimize airflow and maintain the correct air-fuel ratios without needing a separate engine tune. The rotomolded air filter housing is designed to keep hot engine bay air away from the filter, ensuring that only cool, dense air enters the engine for maximum performance. This kit includes everything needed for a direct-fit installation, meaning it bolts right up to your existing setup.

This Injen Power-Flow intake system is a well-built upgrade for your truck or SUV. It comes with a serviceable Injen SuperNano-Web dry air filter and is backed by Injen's limited lifetime warranty. For 2004-2008 models, this intake also carries a CARB Executive Order number, indicating it meets emissions requirements for those years.
