WTF are Build Bux?

You've been asking for this bad sally for a while and it's finally here. The intake the for the 15+ STI can be thought of as a hybrid of the tube and filter used in the 08-14 WRX intake and the Stealthbox heat shield used in the 2015+ WRX intake. Small design changes were made, but the overall fit and performance is approximately the same.

Part #: 060078

Quick Specs

  • Hybrid Cold Air/Short Ram Design - Combining the advantages and eliminating the negatives of both traditional intake designs
  • Air straightener - Dimensionally mimics the factory configuration for accurate MAF sensor readings
  • MAF sensor location - Inside heat shield, isolated from engine bay heat
  • Custom reusable high flow air filter - Integrated velocity stack entrance smooths incoming air
  • StealthBox Heat Shield - Sleek, unique design looks KILLER in your engine bay and keeps the heat of the engine bay from affecting performance
  • Made in the USA - Right here in Minnesota, in fact
  • 30min Installation - Extremely simple with our written and video guides

Why GrimmSpeed?

Sometimes, this explanation is long and technical, especially where performance is concerned. This time, it's simple. The GrimmSpeed engineering and manufacturing teams are known for designing and producing products that use high quality materials, offer perfect fitment and superior craftsmanship and are durable. These intakes are no different and feature the proven performance of the 08-14 WRX EJ motor intake (third party results coming soon) with a look and feel that set it apart from the competition. With the Stealthbox intake heat shield, you no longer need to look like you've got a shoe box hanging out where your factory airbox used to be.

Of course, like all GrimmSpeed products, we stand behind these kits 100% and our goal is to offer you a customer experience that makes you want to stand behind them as well.

GrimmSpeed Intake Kit Includes:

  • 1x Intake Tube w/ TIG welded MAF flange and Air Straightener
  • 1x High-flow Oiled Filter
  • 1x Hump Hose Connector
  • 1x Stealthbox Heat Shield Assembly
  • 3x Hose Clamps
  • 2x MAF Flange Screws
  • 3x Precut Rubber Sealing Strip
  • 1x MAF Wire Grommet

Options

  • Red Intake Tube
  • Black Intake Tube

    ** INSTALLATION NOTE - Take care to install the air filter onto the intake tube properly. Push the filter onto the tube no more than 1" before tightening the clamp. This will ensure that the velocity stack within the filter is allowed to function properly! **

    Quality & Performance

    Grimmspeed definitely makes a quality product and it shows as soon as you open a box from them. Packaging is top notch, there’s no way this intake is getting damaged in shipping. Installation is super easy as well as fast. After some other mods I had my car pro tuned and saw some decent gains even being conservative. I can’t speak on just the intake without anything else but I would imagine a portion of what I ended up with was attributed to the intake. The shield is very stealthy (hence the name), I did have to modify it slightly to fit my intercooler piping but I think it came out good. Thanks IIR you guys are the sh*t from start to finish, I’ll be a loyal customer forever
