Buying Guide: What to Look For in an aFe Momentum Intake
When I started looking for a performance intake, the aFe Momentum GT line was at the top of my list. But with so many part numbers and applications, figuring out the right one for my truck felt a bit overwhelming. After spending a good amount of time researching and talking to folks who’ve installed them, I learned what really matters. It’s not just about picking the shiniest box; it’s about matching the intake to your vehicle and your goals.
The first thing I check is the fit. This seems obvious, but it’s easy to get excited about the horsepower claims and overlook compatibility. aFe makes specific intakes for specific models. For example, the part for a 2021 Ford F-150 3.5L EcoBoost is different from the one for a 2022 Ram 1500 5.7L Hemi. I always go to the manufacturer’s website, use their vehicle selector tool, and double-check the part number. There’s nothing worse than getting a package and realizing it doesn’t fit your engine bay.
Next, I look at the filter itself. The Momentum series uses a high-flow, dry-style filter. I personally prefer this over oiled filters because there’s no risk of messing up your mass airflow sensor with excess oil. The pro dry S filter is supposed to be really effective at trapping dirt while still letting a ton of air through. I also consider the construction of the intake tube. The roto-molded polyethylene tubes are great because they don’t transfer heat like metal tubes can, which helps keep the incoming air cooler and denser.
Finally, I think about what I want to get out of it. Is it just for the cool sound when I step on the gas? Or am I trying to pair it with a tune and an exhaust for more serious gains? For most daily drivers, the basic gains in throttle response and the aggressive engine note are the main benefits. I also make sure to look at the installation process. Some are truly a “do-it-yourself” project with basic tools, while others might be a bit more involved. Reading through a few forum posts or watching an installation video for my specific vehicle usually gives me a good idea of what I’m in for. Taking the time to get the right aFe Momentum Intake for your vehicle makes all the difference in the world.
FAQ
Will an aFe Momentum Intake void my car’s warranty?
This is probably the most common question I see, and the answer is generally no, but with a big asterisk. In the US, the Magnuson-Moss Warranty Act states that a dealer must prove that your aftermarket part directly caused a failure to deny a warranty claim. So, if your infotainment screen goes blank, the intake has nothing to do with it. However, if you have an engine issue that the dealer claims was caused by contaminated air from the intake, you might have a fight on your hands. It’s always a good idea to keep your stock airbox so you can swap it back if you need to take the vehicle in for major engine work.
How much horsepower can I really expect to gain?
It’s important to have realistic expectations. The advertised gains, often around 10-20 horsepower and 15-30 lb-ft of torque, are usually achieved under ideal testing conditions. In the real world, you’ll likely feel the improvement more in the throttle response than seeing a huge number on a dyno sheet. The engine breathes easier, so it feels more eager and alive, especially when you put your foot down. The sound it makes also adds to the feeling of increased performance.
Is this a difficult install for someone with basic tools?
From my experience and from what I’ve gathered from others, most aFe Momentum Intake kits are designed for a straightforward installation. If you’re comfortable with a socket set, screwdrivers, and following instructions, you can probably handle it. The instructions are usually detailed with good pictures. The job mostly involves removing the old airbox and tubing and bolting in the new system. Taking your time and not forcing anything is the key. There are also plenty of vehicle-specific installation videos on YouTube that can walk you through the entire process.
Do I need to get my vehicle tuned after installing the intake?
For most modern vehicles, no, a tune is not required. The engine’s computer (ECU) is smart enough to adjust the air-to-fuel ratios within a certain range to account for the increased airflow. You’ll get the benefits of better throttle response and sound without a tune. However, if you’re looking to maximize the performance potential of your aFe Momentum Intake for your vehicle, pairing it with a custom tune is the way to go. The tune can take full advantage of the improved airflow and often yield more significant power gains.
How often do I need to clean and maintain the filter?
The maintenance schedule isn’t too demanding. aFe recommends cleaning the Pro Dry S filter every 15,000 miles under normal driving conditions. If you drive in a very dusty or off-road environment, you’ll want to check and potentially clean it more often, maybe every 5,000-10,000 miles. The cleaning process is simple: you tap it gently to remove loose debris and then use low-pressure air from the inside out to blow out the trapped dirt. There’s no oiling required, which makes upkeep a lot simpler.
