If you’re looking to give your 2006-2007 Subaru WRX a serious boost, check out the HPS Performance 827 Series Air Intake Kit. This isn’t just some flashy piece of gear; it’s a game changer. We're talking about a 2-3/4 inch mandrel-bent aluminum tube that’s designed to maximize airflow and enhance performance. You can expect gains of about +21.3 whp and +20 ft/lbs of torque. That’s not just numbers on a sheet—it's a noticeable difference when you hit the gas.

One of the coolest things about this kit is the heavy-duty powder-coated steel heat shield. It does a fantastic job of blocking hot air from messing with your air filter, so you get cooler, denser air for better combustion. Plus, the installation is straightforward; it comes with a manual that has clear pictures and step-by-step instructions. Seriously, you don’t need to be a mechanic to get this thing in. And no tuning is required, so you won’t be throwing a wrench into your setup.

The lightweight aluminum tube replaces the stock air box, which is a notorious bottleneck in the WRX. This upgrade not only improves airflow but also offers excellent heat dissipation, meaning your engine can breathe a little easier. The kit also features reinforced silicone hoses and industrial-grade stainless steel T-bolt clamps that are built to last, even if you’re pushing your car to the limits.

And let’s not forget about the HPS Performance Air Filter included in the kit. It's washable and reusable, which is a big plus for anyone looking to save some cash on replacements. This filter is designed to trap dirt down to 5 microns while still allowing for superior airflow. The specially formulated lightweight synthetic oil creates an ionic bond with the stainless steel mesh, ensuring that dirt gets trapped without affecting your sensors.

Just a heads up, this kit isn’t CARB compliant, so keep that in mind if you're in a state that requires emissions testing. But for those of you who just want to feel the power and hear that sweet turbo spool, this is an awesome choice.
