This option emphasizes authenticity with Genuine OEM Mopar parts. It is designed for 5.7L and 6.4L cold air intake kits and is compatible with multiple Mopar P/N configurations, ensuring a correct fit within the factory intake system. The emphasis here is on reliability and official compatibility for a factory-supported upgrade route.
EVIL ENERGY Cold Air Intake
EVIL ENERGY offers compatibility across Chrysler 300, Challenger, and Charger models with a 3.6L V6. The kit promises easy installation in about 40 minutes and includes a high-efficiency multi-layer cotton air filter with a washable pre-filter. A key feature is the ability to deliver improved throttle response and stronger hill-climbing performance, with a focus on filtration efficiency exceeding 98% for contaminants.
KAX 4″ Cold Air Intake Kit
KAX emphasizes broad vehicle fitment across multiple Dodge and Chrysler models. The kit features a lightweight aluminum intake pipe with a polished finish to maximize airflow while delivering a deep, sporty sound. It’s designed to improve throttle response and provide a measurable 8-10% horsepower boost and 6-8% torque increase, depending on the engine configuration.
aFe Momentum GT Cold Air Intake
The Momentum GT utilizes a Pro 5R filter with five layers of progressively finer mesh cotton gauze. The large 9-inch tall inverted top filter, CAD roto-molded tubes, and design compatibility with Hellcat headlight intake for 2015 Dodge Challenger models highlight its performance-first approach. This option targets higher-end enthusiasts seeking substantial filtration and flow improvements.
PTNHZ Cold Air Intake Kit
PTNHZ offers a complete kit with a heat shield to keep hot under-hood air away from the intake element, supporting cooler air charges. It covers the 2011-2023 Charger/Challenger/300 3.6L engines and emphasizes reduced air resistance to improve power delivery and combustion efficiency. The kit pairs an optimized intake path with robust shielding for consistent performance gains.
Buying Guide: Key Purchase Considerations
- Engine compatibility: Verify fitment for your Challenger’s year, model, and engine size (V6 or V8 variants).
- Filtration quality: Look for washable, reusable filters and multi-layer cotton gauze or high-efficiency designs to balance airflow with debris protection.
- Airbox and heat management: A hybrid or heat shield design helps keep intake air cooler, reducing density altitudes and improving performance.
- Ease of installation: Consider kits that require minimal cutting or drilling and come with clear instructions and hardware.
- Audiology of sound: Some kits increase intake roar; others maintain a quieter profile. Choose based on your preference for sportiness vs. refinement.
- Durability and materials: Aluminum or corrosion-resistant components promote long-term reliability in varying climates.
- Maintenance and service life: Reusable filters save money and reduce waste, but require periodic cleaning and re-oiling where applicable.
- Warranty and brand support: OEM-sourced or proven aftermarket brands often offer stronger support and documentation for installation.
- System balance: For engines with factory tune, consider whether you’ll need a tune or ECU recalibration to maximize gains.
