STILLEN Subaru WRX Intake – A Success Story
STILLEN expertise in extracting major power gains without upsetting factory ECU settings is legendary. Years of engineering intercoolers, turbo upgrades, exhausts and intakes comes in handy when analyzing the design of the stock intake on a vehicle like the WRX.
The STILLEN 2015-2018 Subaru WRX intake was designed to optimize airflow and give the MAF sensor the most accurate reading possible.
The dyno results speak for themselves with a factory-like AFR curve and massive gains across the power band:
All testing was done with stock tuning. That’s important, because it gives you options:
- Today you can add significant power without investing in tuning software.
- Tomorrow you run it with tuning, whether custom or stage 1 & 2 tuning from Cobb.
No matter your resources or needs, the 2015-2018 Subaru WRX intake is there for you – tuning or no tuning.
Design Details:
When STILLEN Engineers were developing the WRX Intake they were already aware of the issues of other intake kits on the market. The fluctuating AFR readings made it clear that there needed to be adjustments made for MAF Sensor to get proper readings to the ECU and keep everything safe while still making more power. For this we looked at the design of the factory intake and MAF Sensor placement to see how the stock setup was communicating accurate information.
The Best Choice
So let’s take a look at the STILLEN Subaru WRX intake’s resume so far: Powerful? Check. Cost-effective? Check. Versatile? Check. Dependable? Yes sir. And here’s why:
You may have read that running an aftermarket intake on a stock tuned WRX is unsafe. When intakes were first being designed for the WRX, some manufacturers overlooked crucial details.
AFR’s were not closely monitored or data logged and the misinformation may have scared off the WRX community a bit.
Let’s set the record straight: here at STILLEN we’ve logged over 30,000 miles of operation with our cold air intake on engines with no tuning.
Zero check engine lights.
Zero issues.
Thirty some horsepower.
So here’s the best kept secret tip of the day:
Whether it’s the first or the final performance hop up for your 2015-2016 WRX, the STILLEN cold air intake might just be the best.
The STILLEN 2015-2018 Subaru WRX intake is currently CARB pending but we expect to have the intake fully smog legal in the near future.
