HPS Cold Air Intake Kit

2008–2015 Scion xB 2.4L (xB2)

837-501R

Overview:

The HPS Performance 837 Series Cold Air Intake Kit is engineered specifically for the 2008 to 2015 Scion xB 2.4L, offering a significant upgrade over the factory intake system. Designed for enthusiasts seeking improved horsepower, torque, and throttle response, this intake kit relocates the air filter outside the engine compartment to draw in cooler, denser air. Whether you are a daily driver or a performance-minded owner, this kit enhances your vehicle’s combustion efficiency without requiring any tuning or modifications.

With a durable and lightweight 3-inch mandrel-bent aluminum intake tube finished in vibrant red, the system optimizes airflow while dissipating heat effectively. The kit also converts easily to a shortram configuration, providing flexibility to suit your preferences and installation needs.

Key Features:

This cold air intake kit combines advanced materials and thoughtful design to deliver reliable performance gains and lasting durability:

• 3-inch mandrel-bent aluminum intake tube replaces the restrictive factory air box for optimized airflow and excellent heat dissipation.
• Relocates the HPS Performance air filter outside the engine bay to ensure the coolest possible air inlet temperature.
• Includes race-proven reinforced silicone couplers and industrial-grade 100% stainless steel T-bolt clamps for secure, leak-free connections under extreme conditions.
• Washable and reusable HPS Performance air filter with superior filtration and airflow, manufactured in the USA by Green Filter.
• Fine-tuned by HPS Performance to maximize power output through the top-end power band.
• Converts easily between cold air intake and shortram configurations for installation flexibility.
• Durable red anodized finish on the aluminum tube for corrosion resistance and a striking engine bay appearance.
• Includes a detailed installation manual with clear step-by-step instructions and images.

Construction & Design:

The intake tube is crafted from lightweight mandrel-bent aluminum alloy, ensuring smooth airflow with minimal turbulence. This design not only improves engine breathing but also provides excellent heat dissipation to keep intake air temperatures low. The reinforced silicone couplers are engineered to withstand high temperatures and pressures, while the stainless steel T-bolt clamps guarantee a tight, reliable seal that won’t loosen over time.

The HPS air filter features a woven cotton element that traps dirt particles as small as 5 microns without sacrificing airflow. It is treated with a specially formulated synthetic oil that bonds to the stainless steel mesh, enhancing filtration efficiency and protecting sensitive engine sensors. Low-pressure injection molding reduces rubber seepage onto the filter element, increasing airflow by up to 25% compared to traditional high-pressure molded filters.

Installation & Fitment:

This intake kit is designed for a straightforward, bolt-on installation with no cutting, drilling, or special tuning required. It uses factory mounting points and OEM air inlets, ensuring a secure fit and maintaining the vehicle’s original air-fuel ratio. The kit does not trigger the check engine light (CEL) and is compatible with the stock engine management system.

• No modifications or tuning necessary for installation.
• Includes all necessary mounting hardware and clamps.
• Comes with a comprehensive installation guide featuring clear images.

What's Included:

• HPS Performance 3-inch mandrel-bent aluminum intake tube (red finish)
• HPS Performance washable and reusable air filter (Part # HPS-4276)
