Subaru WRX Air Intake - (Hi-Flow Intake w/ Polyurethane Cover and Aluminum Heat Shield) [VA1] - 402000
Increase engine performance with the STILLEN air intake for Subaru WRX VA1. The Hi flow intake features the most optimal horsepower and torque gains. This STILLEN Subaru WRX air intake has a black finish. This VA1 WRX intake provides a better air flow to the engine with the smooth surface tubing construction.
Everyday your car's engine is drowning in heat, breathing in hot stagnant air, and not allowing your car to breathe correctly is making it sick from the factory restrictive air box. The restrictive OEM airbox gives you poor miles per gallon, terrible power and makes you feel like taking the car back to the dealership. Everyone knows that a cooler air charge is denser with oxygen and thus makes more horsepower, so a cool intake air charge is critical. When in stop and go traffic, unshielded open filters will just suck in hot engine bay air, and as a result, perform like garbage- like the car fell on its face.
Put an end to that nonsense once and for all with the STILLEN Hi-Flow Intake for 2015-18 Subaru WRX. This heat shielded design helps keep hot engine bay air away from the intake inlet, and since it's compatible with the Factory Air Duct, it draws in the coolest possible air charge for maximum output. The beautiful sound of a high flow intake is one of the best things to hear from under the hood of your Subaru WRX. The natural sound of the engine breathing in cool air on a cold winter morning will send a chill down your spine! Exhilarating is an understatement.
You can expect a massive amount of horsepower and torque from this simple bolt on intake -as intakes go, this one delivers an utterly absurd amount of power - we're talking a THIRTY, that's 30AWHP and 32AWTQ GAIN*! Whereas most intakes might deliver 10-15hp on the average turbo car, this is double that - this is even more impressive because this is a SUBARU- these are ALL-WHEEL-HORSEPOWER numbers.

Considering that factory restrictive air box is pulling in power-robbing hot air, this intake is one of the first modifications you should add to your build, because the intake system benefits not only the driver, but the engine will also benefit from the STILLEN Hi-Flow Air Intake for 2015-2016 Subaru WRX. The driver will experience a variety of sensory stimulation, from hearing the fresh sound of air being forced through the filter, as it travels into the aluminum mandrel bent intake tubing. The feeling when you slam your foot on the gas pedal, would throw you back in your seat, in return giving you a big smile and feeling of excitement as the engine screams down the pavement. This feeling came from the extreme increase in throttle response and torque gains that was received from the STILLEN Hi-Flow Air Intake for Subaru WRX.
The engine will benefit the most from the hi-flow air intake due to the engine's intake manifold receiving cooler temperatures than before with a factory restrictive air box. You will also gain miles per gallon (MPG) from the all the less restriction of a proper air filter and redesigned intake tube. It is a simple modification to your WRX that will provide everything you need to make a lot of power without having to tune the vehicle. The power is all natural without having to tune the vehicle, this STILLEN Hi-Flow Air Intake for the 2015-2016 Subaru WRX will increase the horsepower gain to 30HP and 32-foot pounds of torque*, to the wheels! Dyno chart results prove the power ban on California 91 Octane fuel.

One of the notorious issues of the 15+ WRX and its turbo four is that it's especially sensitive. Some early intakes would often set CELs, or worse, cause the engine to operate with an unsafe Air-Fuel-Ratio. This particular generation of WRX has a reputation for blowing up if you look at it funny, so it's worth saying that 2+ years and tens of thousands of miles later, this intake is still performing well for several WRX drivers on our staff who have had this intake equipped since release.
At STILLEN, every intake is specifically designed to work well with the OEM ECU - meaning no check engine light, and safe, reliable performance. We applied that same philosophy to the WRX.
The factory engine mapping produces a noticeable drop in power at around 4,500 RPM. This reduction in power is noticeable in both horsepower and torque. By redesigning the air intake tract and producing a smoother, less turbulent air flow that smooths out the power band and reduces the effect of this dramatic drop.
The intake is a mandrel bent black powder coated aluminum tube and is compatible with the factory air ducting for straightforward installation. The intake tube comes with High Quality Washable Oiled Filter that can be cleaned regularly. Further tailoring this intake for street use is the fact that it uses the factory mass air flow sensor wire harness location, so there isn't any issue with the factory computer throwing a check engine light code. STILLEN offers this intake with oiled or dry filters depending on your desire.
