Airflow is everything, and nobody understands that better than aFe Power (Advanced Flow Engineering). Since the late ’90s, they’ve been designing intake, exhaust, and filtration systems that bring serious performance gains to both gas and diesel platforms. Whether it’s a street-driven Mustang, a track-ready BMW, or a workhorse diesel truck, aFe builds gear that improves flow, unlocks horsepower, and sharpens response without sacrificing reliability.
At Lethal Performance, we stock a wide range of aFe Power intakes, exhausts, and filters, so you can dial in your ride with parts built to perform. From the aggressive growl of an aFe Power exhaust to the efficiency of a Pro DRY S filter, these upgrades give you seat-of-the-pants gains and dependability you can count on in the long term.
Watch step-by-step as the aFe Momentum GT intake is installed on a 2020+ Explorer ST, showing just how straightforward the process really is. If you’ve ever wondered how much an intake can wake up your SUV, hit play.
aFe Power centers its catalog on airflow efficiency and exhaust tuning. Their catalog covers a wide spectrum, but each category is engineered with the same mission: to maximize performance without compromising drivability.
From the one-piece sealed Momentum series to traditional open-element designs, aFe intakes are engineered to reduce restriction and deliver colder, denser air. Many come with options like the Pro DRY S filter, which is washable and reusable.
Designed to pair with their intake systems, these cat-back and axle-back kits are tuned for power and sound. Expect mandrel-bent tubing, stainless construction, and bolt-on fitment.
aFe built their name on filters. Options like the Pro DRY S deliver solid filtration without needing oil, while oiled filters like Pro 5R maximize flow.
Heavy-duty trucks benefit from aFe diesel intakes and intercooler tubes, which reduce EGTs (exhaust gas temps), improve towing power, and extend engine life.

Airflow is the foundation of performance. Stock intakes and exhausts are restrictive, designed and installed more for noise regulations than horsepower. Swapping in aFe Power upgrades changes how your vehicle breathes, and that translates directly to how it performs.
aFe intakes and exhausts are dyno-proven to free up horsepower.
Filters like the Pro DRY S keep your engine safe while saving you time.
Whether you’re in a Mustang or a Power Stroke, aFe has options built for your needs.
Upgrading airflow is the first step, but it works even better when you connect the dots with other performance mods.
Pair an aFe intake or exhaust with a custom tune to unlock the full gains. More airflow means nothing if your ECU isn’t calibrated to use it.
Superchargers and turbos thrive on cold, unrestricted airflow. aFe’s Momentum systems and charge pipes feed boost with less restriction.
When airflow goes up, your fueling has to match. Pair aFe upgrades with higher-flow injectors, stronger pumps, and a tune for max reliability.
aFe parts integrate seamlessly with headers, intercoolers, and catbacks from other brands, making them a perfect base layer in any build.

aFe doesn’t limit themselves to one brand; they build systems for a wide range of modern performance platforms. At Lethal Performance, you’ll find aFe parts for:
Whether you’re chasing horsepower or better throttle response, or just want your ride to breathe easier, aFe Power has something for you. Here are answers to common questions about aFe intakes, filters, and exhausts.
Many aFe intake systems carry CARB EO numbers, making them legal for use in emissions-regulated states like California. Always check the specific part listing at Lethal Performance to confirm compliance for your vehicle.
aFe exhausts are dyno-tested for real gains. Mandrel-bent tubing, high-flow mufflers, and stainless construction reduce back pressure while adding a deeper, more aggressive tone without obnoxious drone.
aFe diesel intake systems reduce restriction, lower EGTs (exhaust gas temps), and improve turbo spool. For towing and heavy-duty work, this means more pulling power, better throttle response, and longer engine life.
Every build starts with airflow, and nobody does it quite like aFe Power. Whether you’re chasing dyno numbers, daily drivability, or towing confidence, aFe intakes, exhausts, and filters deliver results you can feel every time you hit the throttle. Lethal Performance carries the full lineup, so if you’re ready to wake your ride up, we’ve got the parts to make it happen. Breathe deeper, drive harder with aFe Power at Lethal Performance.
