Volant F150 Closed Box CAI Kit
The Volant Closed Box CAI Kit features a premium housing and silicone connectors designed to minimize airflow restriction. Its filtration system leverages Ultra-Web nanofibers, which capture contaminants efficiently on the surface while maintaining lower flow resistance, supporting improved throttle response and potentially better engine efficiency in daily driving and light towing scenarios. This kit is tailored toward Ford F-150 and Raptor models with the 3.5L EcoBoost engine.
Corsa Bronco CAI With DryTech 3D Filter
Designed for the 2021-2022 Ford Bronco with the 2.3L engine, this closed box intake emphasizes heat shielding to keep intake air temperatures down, and it offers reusable filtration options (DryTech or MaxFlow). The DryTech 3D dry filter helps reduce maintenance while providing strong filtration performance. The outflow advantages over stock systems can improve throttle response in stop-and-go driving and light off-road use.
Volant 15553 Pro 5 Filter Enclosed CAI
This Volant Pro 5 system features an oversized closed air box that increases air volume and flow, aiming to improve power delivery and throttle response. The enclosed design helps shield the air intake from radiant heat and debris, making it a viable option for daily driving and moderate performance tuning while maintaining compatibility with multiple engine layouts in the Volant lineup.
Corsa Bronco CAI With MaxFlow
Similar to the DryTech variant, this MaxFlow-equipped Corsa closed box intake is designed to outflow the stock system and reduce intake air temperatures via effective heat shielding. The MaxFlow option emphasizes long-term filtration performance, with reusability and filtration efficiency in mind for Bronco enthusiasts seeking sustained performance gains and reliable operation in varied climates.
Volant Closed Box With Cold Air Scoop
The Volant 382406 model pairs a closed box with a dedicated cold air scoop, promoting cooler intake air temperatures and potentially improved engine efficiency. The design emphasizes a tight seal and compatible hardware to ensure a reliable, low-restriction air path in daily driving or light performance tuning scenarios.
Volant Cold Air Intake Kit With Pro5 Filter
Volant’s Pro5 filter-equipped kit combines a closed air box with a robust filtration setup to deliver durable airflow performance. The kit integrates a complete intake path, with hardened clamps and connectors designed for long-term service in a variety of driving conditions, including urban commuting and highway cruising.
Buying Guide
- Compatibility: Confirm fitment for your vehicle year, make, and model. Some brands design variants for specific engines or body styles, such as Ford F-Series or Bronco platforms.
- Filtration technology: Look for filters with surface filtration, such as Ultra-Web or DryTech media, which can capture contaminants on the surface with low airflow restriction.
- Heat management: Heat shields, cold air scoops, and dedicated intake paths help minimize intake air temperatures, improving performance and efficiency.
- Air box design: Oversized or reinforced boxes can increase air volume and reduce bottlenecks, but ensure the overall ducting remains practical for your engine bay.
- Maintenance and serviceability: Reusable filters and modular components reduce ongoing costs and downtime. Check filter accessibility and cleaning intervals.
- Durability and hardware: Premium clamps, silicone couplers, and corrosion-resistant materials extend the life of the intake system in harsher environments.
- Warranty and support: A robust warranty and clear replacement parts availability add long-term value, especially for vehicles used in towing or off-road conditions.
- Noise and drive quality: Closed box systems can affect intake noise; consider your preference for a deeper tone versus a quieter cabin experience.
- Installation effort: Some kits require moderate mechanical skills and basic tools; others may need professional installation. Review included instructions and mounting hardware.
- Performance goals: Define whether you seek a noticeable throttle response improvement, increased horsepower, or simply a cooler, cleaner intake environment for the engine.
