HPS Long Ram Cold Air Intake System | 2015-2017 Subaru STi (837-573) HPS Silicone Hoses

Long Ram Air Intake System w/ Heat Shield by HPS

Built for performance and show, the HPS Polish cold air intake kit for 2015-2017 Subaru WRX STI 2.5L Turbo relocates the air filter outside of the engine compartment to deliver the coolest air inlet temperatures. Compare to the tradiational shortram air intake, HPS long ram cool 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 +19.4 Whp horsepower, +20.5 Ft/lbs torque and improve throttle response.

The included installation instruction has clear pictures and description to guide the installer throughout the whole process. The kit does NOT require tuning and no modification is required, however, removal of front bumper is necessary during the installation. HPS light weight mandrel-bent aluminum alloy piping replace the stock restrictive air box and optimize the air flow. HPS cold air induction system features HPS signature race proven reinforced silicone hoses and industrial grade 100% stainless steel T-bolt clamps, which ensure the durability and reliability during the extreme driving condition.

The included High-Flow conical air filter designed to provide increased surface area and dust capacity. This extra surface area provides even more airflow at lower restriction than a standard replacement filter that is limited to the size of the factory air box. The oversize air filter also captures more dirt increasing the service life before a cleaning is required (up to 100,000 miles).
