GrimmSpeed Red Post MAF Hose Kit Subaru STI | WRX | Legacy GT | Outback XT | Forester XT 2005-2021
$84.00

Looking to spruce up your engine bay? Let’s be real—some factory parts are just plain ugly, and the stock post MAF hose is one of those that really needs to go. If you're like me, you want your ride to look good under the hood, and that’s where the GrimmSpeed Post MAF Hose Kit comes in. It’s not just about looks, though; this hose tackles the shortcomings of the OEM part head-on.

What makes this hose a must-have? For starters, it’s constructed from 4-ply reinforced silicone. This stuff is tough as nails and can handle the heat and pressure without skipping a beat. Plus, it’s flexible enough to install without any headaches, but sturdy enough that you won’t have to worry about it collapsing under vacuum. Say goodbye to that flimsy factory rubber!

Now, let’s talk about airflow. The GrimmSpeed hose features a smooth inner surface that eliminates those annoying pockets caused by the OEM's corrugated design. Those folds might help with flexibility, but they also mess with airflow. Our tapered center portion ensures that the inner diameter matches perfectly with your OEM air box and turbo inlet, preventing any airflow disruptions that can create pesky vortexes. This means you get a more seamless flow, which is exactly what you want for optimal performance.

If you're planning to pair this with the GrimmSpeed DRY-CON Panel Air Filter, you’re setting yourself up for success. It’s the best way to get the most out of your factory intake system until you’re ready to take the plunge into a full GrimmSpeed intake upgrade.

Features:

  • 4-Ply Reinforced Silicone—super durable, available in red or black
  • OEM fitment—easy install, no modifications or tuning required
  • Seamless Flow—CAD optimized design for maximum efficiency
  • High-Quality Breeze Hose Clamps included
  • GrimmSpeed Logo—show off your favorite brand!

Fitments:

  • Subaru STI 2008-2021
  • Subaru WRX 2008-2014
  • Subaru Legacy GT 2005-2009
  • Subaru Outback XT 2005-2009
  • Subaru Forester XT 2009-2013

So, if you've got a Subaru from the list above, this GrimmSpeed Red Post MAF Hose Kit is the upgrade you didn’t know you needed. It’s all about making your engine bay look sharp while improving performance—what’s not to love?
