K&N Performance Air Intake System for 2007-2009 Ford Mustang 4.6L V8, 15 HP Gain

Alright, let’s talk about this K&N Performance Air Intake System for the 2007-2009 Ford Mustang GT. If you're looking to give your ride a little extra kick, this setup is worth considering. It’s made from high-density polyethylene (HDPE), which is a fancy way of saying it’s tough and designed for serious airflow. This isn’t just for show; it’s going to help your engine breathe better and give you a solid boost of around 15 horsepower and torque at 6000 RPM. That’s a nice little bump when you’re hitting the gas.

One of the standout features is the washable and reusable High-Flow Air Filter. It’s got that oiled cotton media that can go up to 100,000 miles before needing a clean under normal driving conditions. So, you can forget about constantly swapping filters. Just give it a rinse, and you’re good to go. Plus, the oversized conical design means it’s pulling in tons of air, which is exactly what you want when you’re trying to get the most out of your V8.

Now, let’s not overlook the custom heat shield. It does a great job of keeping the intake air cooler by blocking out some of that engine bay heat. Cooler air means better performance, and that’s what we’re after, right? Installation is a breeze too. If you’ve got basic tools and a little know-how, you can typically get this installed in under an hour. Just make sure to check the product specs for CARB status if you’re in California, as some intakes aren’t street legal there.

Here’s a quick rundown of what you get:

• No air box included, but it’s designed to fit right in.
• Filter color? It’s red, so it looks good under the hood.
• Made with cotton gauze for that high-flow action.
• Round outlet shape for easy fitment.
• Comes with 6 stainless steel clamps—no worries about rust.
• Includes all necessary ports for your specific applications.
• And yes, the mass air flow sensor adapter is included.
• Weighs in at about 10.3 lbs, so it’s lightweight.
