GrimmSpeed StealthBox Intake BLACK Subaru WRX 2015-2019

If you are looking to upgrade your FA20DIT with a high performance intake, look no further. The GrimmSpeed Stealthbox Intake for the 2015+ WRX is the complete package. High quality and attention to detail leaves nothing to be desired. There are many variables to be considered when designing an upgraded intake. And the Subaru WRX can be pretty picky about the intakes being ran on it. That is why GrimmSpeed has considered so many elements in the design process. MAF Diameter, MAF Placement, bend angle, filter location, and heat shield design were all looked at and planned out to get you the best output for your money.

A few things to note about the design are as follows. 

Quick Specs

• Low Bend Angle - Reduces the amount of restriction in the intake getting more air to your turbo and allows you to make more power. 
  
• Stealth Box - Designed to keep heat away from the MAF Sensor, increases accuracy of readings and keeps fresh air moving around the filter.
• Made in the USA - Manufactured in Minnisota. Read more about GrimmSpeed by clicking HERE

The GrimmSpeed StealthBox Intake is made out of 6061 Aluminum alloy and features a CNC Machined MAF Flange precision welded to a mandrel bent pipe. The MAF location is an important feature of the StealthBox Intake and is placed near the filter in the most consistent cross-sectional flow area. Mounting brackets are laser cut and CNC bent to ensure perfect fitment. The StealthBox Heat Shield is also laser cut and CNC bent and then hand assembled before recieving a durable powdercoat finish. 

As far as performance is concerned this intake is not lacking. It will open your FA20DIT powered WRX up to a whole new level. Dyno/long term road testing has been performed to ensure you get the best bang for your buck. With tuning, you can expect up to a 14.3% gain in torque and a 9.6% gain in horsepower at the wheels. This is power you can feel! GrimmSpeed themselves picked up 32ftlb's of torque and 21whp without running higher boost.

As with any intake for the 2015+ WRX, tuning is required after installation to maximize gains and safety.
