Installing a cold air intake on your F80/F82 BMW M3/M4 is one of the easiest, most satisfying upgrades you can do to the S55 twin-turbo in an afternoon. The factory 2015–2020 M3 and M4 make 425 to 444 horsepower from a 3.0L twin-turbocharged inline-six that is genuinely starved for air the moment you add boost with a tune. Swapping the restrictive OEM airboxes for a high-flow sealed intake wakes up throttle response, adds a hungry induction growl under load, and—on a tuned car—frees real power. This step-by-step guide walks through the full install (about 30 to 45 minutes with hand tools), the exact parts and torque you need, and how to pick the right intake for your S55.
Our Verdict
For most F80/F82 owners, the aFe Momentum GT Pro DRY S is the best cold air intake to install—a fully sealed airbox, +46% more airflow, and a no-oil filter that needs almost no maintenance.
It drops into the factory mounting locations, keeps intake air isolated from engine heat, and aFe dyno-claims up to +17 horsepower and +19 lb-ft. Want a carbon showpiece under the hood instead? Step up to the AWE S-FLO Carbon. On a budget? The aFe Magnum FORCE Stage-2 delivers most of the sound for less.

A cold air intake is a high-flow replacement for your factory air filter and airbox that feeds cooler, less-restricted air to the turbochargers. On the S55-powered 2015–2020 BMW M3 (F80) and M4 (F82/F83), the two OEM airboxes are tuned for silence and emissions, not maximum flow. High-flow intakes like the aFe Momentum GT advertise roughly 46% more airflow than stock and outflow the factory boxes by an average of 30%, which is exactly what a boosted engine wants.
The S55 leaves the factory at 425 hp / 406 lb-ft in the standard M3/M4, 444 hp in Competition trim, 453 hp in the M3 CS/M4 CS, and 493 hp in the track-focused M4 GTS. Because these engines are twin-turbocharged and run a speed-density (MAP-based, MAF-less) tune, they respond strongly to reduced intake restriction—especially once you add an aggressive Stage 1 or Stage 2 flash. On a stock tune, expect the intake alone to add a modest, real-world 5 to 12 wheel horsepower plus sharper throttle and a louder induction note. Pair it with a tune and colder charge air and the same intake supports far bigger gains because it is no longer the bottleneck.
In our Tampa, FL shop, the number-one reason customers install an intake first is the transformation in character: the twin-turbo spool becomes audible, throttle tip-in feels crisper, and the engine bay looks the part. It is the classic gateway mod on the F8x platform.
The aFe Momentum GT uses fully sealed one-piece airboxes that isolate the filters from engine heat.
Tools and Parts You Need for the Install
The good news: a cold air intake on the F8x M3/M4 is a hand-tools-only job with no cutting, splicing, or tuning required to run it. Before you start, gather the following:
- Your new intake kit (aFe Momentum GT, AWE S-FLO Carbon, aFe Track Series, Injen Evolution, or aFe Magnum FORCE)
- 8mm and 10mm sockets or a nut driver
- Ratchet with a short extension
- Flat-blade screwdriver or a pick to release spring/worm clamps
- Optional: a 10mm wrench to disconnect the negative battery terminal
- Clean shop towel to keep debris out of the turbo inlets
Every kit in this guide is a direct fit for the S55 and reuses the factory air ducts and mounting grommets, so you are transferring hardware, not fabricating it. Always confirm your exact year against the kit fitment—most listings cover 2015–2020, but a few are cataloged 2015–2017 or 2015–2019.
Every intake in this guide reuses the factory air ducts and rubber grommet mounts—no cutting required.
How to Install a Cold Air Intake on the F80/F82 M3/M4: Step by Step
Work on a cold engine so you do not burn your hands on the charge pipes. Total time is about 30 to 45 minutes. The S55 uses two separate airboxes—one per turbo—so you simply repeat each step on both sides.
Step 1: Prep the engine bay
Let the car cool completely, pop the hood, and (optionally) disconnect the negative battery terminal with a 10mm wrench. Remove the plastic engine acoustic cover if your kit calls for it by pulling straight up to release the ball-and-socket grommets.
Step 2: Release the factory intake tubes
Loosen the worm-gear clamps where the factory intake tubes meet the turbo inlets. Disconnect the crankcase breather/vent hoses and unclip any intake-air temperature sensor connectors so the airboxes can lift freely. Keep a towel handy to cover the open turbo inlets and stop any hardware from dropping in.
Step 3: Remove the OEM airboxes
The factory airboxes sit in rubber grommet mounts. Pull each box straight up to pop it out of its grommets, then set both aside. This is the moment you see just how restrictive the stock silencing baffles are compared with a high-flow filter.
Sealed carbon and roto-molded airboxes drop into the factory mounting locations for a clean, OE-style fit.
Step 4: Install the new sealed airboxes
Transfer the factory air ducts/scoops to the new intake if the instructions require it, then seat each new airbox into the factory rubber grommets until it clicks home. Sealed designs (Momentum GT, AWE S-FLO, Track Series) fully enclose the filter so it only draws cool air fed by the hood ducts.
Step 5: Reconnect tubes, hoses, and sensors
Slide the intake couplers onto the turbo inlets and tighten the worm clamps evenly—snug and leak-free, roughly 40 to 50 in-lb; do not overtighten and crush the coupler. Reattach the breather hoses and reconnect the intake-air temperature sensors. Double-check that nothing is pinched or loose.
Step 6: Reassemble and verify
Reinstall the engine cover, reconnect the battery, then start the car and let it idle. Listen for smooth running and any air leaks, and blip the throttle to confirm the new induction sound. A drop-in intake needs no tune to run safely, but the ECU will relearn its adaptations over the next few drive cycles.

The Best Cold Air Intakes to Install on Your S55
All five kits below are direct-fit for the F8x M3/M4 and install with the same procedure above. The differences come down to filter media (dry vs oiled), housing material (roto-molded vs carbon fiber), sealed vs open design, and price. Here is what we install most in our Tampa shop.
Which S55 Intake Should You Install? (Comparison)
If you want the strongest all-around pick, install the aFe Momentum GT Pro DRY S: sealed airbox, no-oil filter, and the biggest advertised airflow. Chasing looks and don't mind a race-only note? The AWE S-FLO Carbon is the showpiece. Every one of these installs in the same 30 to 45 minutes.

Frequently Asked Questions
How long does it take to install a cold air intake on an F80/F82 M3/M4?
Installing a cold air intake on the F80 M3 or F82 M4 takes about 30 to 45 minutes with basic hand tools. The S55 has two airboxes (one per turbo), and each drops into the factory mounting grommets, so there is no cutting, drilling, or fabrication involved.
How much horsepower does an intake add to the S55?
On a stock tune, a cold air intake typically adds a modest 5 to 12 wheel horsepower to the S55 plus sharper throttle response and a louder induction note. aFe dyno-claims up to +17 hp and +19 lb-ft for its Momentum GT. The intake's biggest value is removing a restriction so a Stage 1 or Stage 2 tune can make far larger gains.
Do I need a tune after installing an intake on my M3 or M4?
No, a drop-in cold air intake is safe to run without a tune on the F8x M3/M4. Because the S55 uses a MAF-less, speed-density (MAP-based) system, it self-adjusts to the added airflow. A tune is optional but recommended to unlock the intake's full power potential.
Dry filter or oiled filter for the F8x—which is better?
A dry filter (aFe Pro DRY S, Injen nano-fiber) needs no oil and is the low-maintenance choice—you clean it and reinstall it. An oiled cotton-gauze filter (aFe Pro 5R, AWE) can flow slightly more air and gives a more aggressive intake note, but requires careful re-oiling. For most street-driven S55 cars we recommend a dry filter.
Will a cold air intake void my BMW warranty?
Under the Magnuson-Moss Warranty Act, a dealer cannot void your entire warranty simply for installing an aftermarket intake; they must prove the part caused a specific failure. That said, aggressive tuning combined with an intake can affect powertrain coverage, so keep your factory airboxes to reinstall before any warranty service.
Does a cold air intake make the M3/M4 louder?
Yes. A high-flow intake makes the S55's twin-turbo induction and spool clearly audible, especially under throttle. Open tube-style kits like the aFe Magnum FORCE Stage-2 are the loudest, while sealed airboxes such as the Momentum GT add a deeper growl while keeping intake air cooler.
