Overview

HPS Performance 837 Series 2-pieces cold air intake kit (Part # 837-778) for 3rd Gen 2008-2014 Subaru Impreza WRX STI 2.5L Turbo features free-flowing, 3 inch mandrel-bent aluminum tubing and is dyno-proven to deliver an impressive 29.5 horsepower and 27 lb-ft of torque. Experience improved throttle response and quicker acceleration, all while maintaining a safe air-fuel ratio. To maximize performance, the high-flow, washable air filter is strategically relocated outside the engine compartment, drawing in cold air. A heavy duty, powder coated steel heat shield further isolates the filter from engine heat. This bolt-on upgrade replaces your restrictive stock air intake hose and air box with a smoother, two-piece aluminum intake designed for optimal airflow, excellent heat dissipation, and lasting durability. Engineered for reliability even under extreme driving conditions, the kit includes high-temperature resistant silicone hoses and industrial-grade 100% stainless steel T-bolt clamps. Best of all, no tuning or additional modifications are required.

Shipping

Orders are processed in 1–3 business days. In stock parts ship promptly from our partner network. Special-order items either aren’t currently stocked or are built to your spec — expect 4–6 weeks. If a part goes on backorder while your order is in the queue, we’ll reach out and work through discounted alternatives together.

Alaska, Hawaii, U.S. territories (Puerto Rico, U.S. Virgin Islands, Guam, American Samoa, and the Northern Mariana Islands), and international orders carry surcharges — most appear at checkout. Some exceptions (LTL freight, or suppliers who quote freight only after we place the order) won’t. In those cases we’ll reach out with the exact charge before your order moves forward.
