HPS Cold Air Intake Kit

2008–2015 Scion xB 2.4L (xB2)

837-501BL

Overview:

The HPS Performance 837 Series Cold Air Intake Kit is engineered specifically for the 2008 to 2015 Scion xB 2.4L. This intake system replaces the factory air box with a free-flowing 3-inch mandrel-bent aluminum tube and relocates the air filter outside the engine compartment to draw in cooler, denser air. Designed for daily drivers and performance enthusiasts alike, it enhances horsepower, torque, and throttle response without requiring tuning or modifications.

With a convertible design that allows switching to a shortram setup, this intake kit offers versatility while maintaining reliable performance. Its durable construction and high-quality components ensure long-lasting operation even under demanding driving conditions.

Key Features:

This intake kit combines advanced materials and thoughtful design to optimize airflow and engine efficiency. Key features include:

• 3-inch mandrel-bent aluminum intake tube for smooth, unrestricted airflow and excellent heat dissipation
• Relocation of the air filter outside the engine bay to reduce intake air temperature and improve combustion efficiency
• Convertible design allowing easy switch between cold air and shortram intake configurations
• Race-proven reinforced silicone couplers for superior heat resistance and durability
• Industrial-grade 100% stainless steel T-bolt clamps ensuring secure, leak-free connections
• Washable and reusable HPS Performance air filter made in the USA, designed for high filtration efficiency without sacrificing airflow
• Includes detailed installation manual with clear, step-by-step instructions and images
• No tuning or engine modifications required; does not trigger check engine light
• Lightweight aluminum tube finished in vibrant blue for a clean, performance-oriented look

Construction & Design:

The intake tube is crafted from mandrel-bent aluminum alloy, providing a smooth internal surface that minimizes airflow restriction and maximizes volume. This material also offers excellent heat dissipation to help keep intake air temperatures low. The reinforced silicone couplers are engineered to withstand high temperatures and pressure, maintaining a reliable seal during spirited driving or extreme conditions.

The HPS Performance air filter features a woven cotton element that traps dirt particles as small as 5 microns while maintaining superior airflow. Its stainless steel mesh reinforcement resists dents and damage better than traditional aluminum mesh. The filter is treated with a specially formulated lightweight synthetic oil that bonds with the mesh to attract and trap contaminants without affecting sensitive engine sensors.

Performance & Sound

By delivering cooler, oxygen-rich air to the combustion chamber, the HPS 837 Series intake kit promotes a more efficient and powerful combustion process. This results in noticeable gains in horsepower and torque, along with improved throttle response. The system also enhances intake sound, providing a more aggressive engine note without excessive drone.

Installation & Fitment:

This intake kit is designed for a straightforward, bolt-on installation using factory mounting points and hardware. No cutting, drilling, or special tuning is necessary, and the system will not trigger the check engine light. The included installation manual provides clear, detailed instructions with photos to guide you through the entire process.

What's Included:

• 3-inch mandrel-bent aluminum intake tube (blue finish)
• HPS Performance washable and reusable air filter (Part # HPS-4276)
• Heat shield to protect intake air from engine heat
• High-temperature reinforced silicone couplers
• 100% stainless steel T-bolt clamps
• Mounting hardware
