HPS Performance Black Cold Air Intake w/ Heatshield 2015-2020 STI

The HPS Performance 837 Series air intake kit for 2015-2020 Subaru STI 2.5L Turbo offers a free-flowing 2-3/4 inch mandrel-bent aluminum tube induction system by relocating HPS Performance Air Filter outside of the engine compartment to deliver the coolest air inlet temperature.

Compared to the traditional intake setup, HPS Performance 837 Series cold air intake kit delivers cooler air with more oxygen, which translates into a more intense explosion in the vehicle combustion chamber to produce dyno proven performance gains - increase horsepower +19.4 whp , torque +20.5 ft/lbs and improve throttle response while maintaining safe air fuel ratio. The included installation manual has clear pictures and instructions to guide the installer throughout the whole process.

The kit does NOT require tuning and does not trigger CEL light. No modification is required during the installation. HPS light weight mandrel-bent aluminum alloy tube replaces the stock restrictive air box and optimizes the airflow with excellent heat dissipation and long lasting durability. HPS Performance 837 Series cold air intake kit (aka CAI) features race proven reinforced silicone hoses and industrial grade 100% stainless steel t-bolt clamps which ensures reliability, even during the most extreme driving conditions. Proudly made in the United States, the All-New HPS Performance Air Filter is designed with performance in mind, delivering excellent filtration without sacrificing airflow.
