Extreme Turbo Systems Stock Cotton Filter Turbo Intake w/ Oil & Airbox Subaru WRX 2015+

Alright, let’s talk about this intake system for the 2015+ Subaru WRX. If you’re like me, you want something that not only works but gives your ride that extra oomph without the hassle of a retune. This setup keeps the stock size MAF housing, so you can just bolt it on and feel the difference right away. No fiddling around with tunes—just pure, unadulterated performance.

What really sets this intake apart is the custom billet 5" velocity stack. It’s designed to funnel air in as quickly as possible, which is crucial when you're trying to get the most out of your engine. Plus, it’s paired with a sizable K&N filter, giving you a ton of surface area for airflow. Seriously, this thing breathes!

One of the cool features is how the filter is positioned to utilize the factory ram air duct. This means you’re not just getting more air; you’re getting it from a cooler source, which is always a win. And if you’re looking to keep things looking clean and stealthy under the hood, you can opt for the airbox as well. It’s a nice touch that helps isolate the intake from those hot engine bay temps, ensuring you get the coldest, most direct intake charge possible.

Now, let’s break down some specs:
