Best Ford Raptor Cold Air Intake: 2017-2020 Buyer Guide

Choosing the right Ford Raptor cold air intake for a 2017–2020 second-gen truck is the single best $300–$850 you can throw at the twin-turbo 3.5L EcoBoost. Stock, that engine puts down 450 HP and 510 lb-ft, but the factory airbox chokes the turbos the moment you stab the throttle past 4,500 rpm. Swap the restrictive paper element and corrugated plastic tube for a free-flowing tube, oversized filter, and a sealed heat shield, and you free up real airflow without touching a tune. We install these intakes weekly in our Tampa shop, and the difference you feel from a stoplight pull is not subtle. This guide breaks down the five intakes we actually trust on a Raptor, what filter media to pick, and what changes between the 2017 and 2018–2020 trucks.

Why the 3.5L EcoBoost Loves a Cold Air Intake

The second-gen Raptor 3.5L (engine code is the high-output Nano variant) breathes through two parallel intake tracts feeding a pair of Garrett GTDI turbos. From the factory, each tract has its own paper filter inside a shared airbox, and Ford restricts inlet diameter to keep noise and induction roar inside the cabin within F-150 spec. That works fine for grocery runs. It does not work when you are pulling 18 psi of boost up an on-ramp.

A proper Ford Raptor cold air intake does three things at once. First, it doubles the effective filter surface area — the aFe Track Series uses two oversized 6-inch filters versus the small factory pleats. Second, it replaces the restrictive plastic tube with a smooth carbon fiber or aluminum tube that holds laminar flow into the turbo inlets. Third, it seals the filters away from radiant engine bay heat with a closed top and rubber seal against the hood. Cooler, denser air means more oxygen molecules per gram, which the ECU translates into more boost and timing. On a stock-tune Raptor, expect a real-world 12–18 HP and 18–25 lb-ft pickup at the wheels — manufacturer claims like aFe's +18 HP figure are measured at the crank with the same intake on a tuned truck, so reset your expectations accordingly. Add a 91-octane tune from a calibrator like 5 Star or Livernois and the same intake will pick up 30–45 HP.

What to Look For in a Raptor Cold Air Intake

Not every CAI sold for the F-150 platform fits a Raptor cleanly. Here is what we check before we put one on a customer's truck.

Filter media

You have two real choices. Oiled cotton (aFe Pro 5R, K&N, AEM Dryflow) flows the most CFM but requires re-oiling every 30,000–50,000 miles and over-oiling can foul the MAF sensor. Dry synthetic (aFe Pro DRY S, S&B Cotton, Roush ProGuard 7) needs zero oil, just a vacuum and a wash with mild detergent every 25,000 miles, and it cannot wreck a MAF. For most Raptor owners, dry wins.

MAF placement

The 3.5L Raptor uses two MAF sensors, one per intake tract. A good CAI relocates them into a calibrated bung on the new tube at the same distance from the filter as factory, so the ECU does not throw a P0101 lean code. Cheap eBay intakes skip this step. The aFe and Roush kits in this guide all have proper MAF placement.

Heat shield and seal

An open-element "short ram" intake on a Raptor is a heat-soak nightmare in Florida. The factory airbox is fully sealed for a reason. A real cold air kit replaces it with an enclosed box that seals against the underside of the hood with a rubber strip, drawing air from the fender and cowl. If a kit does not have a sealed top, walk away.

CARB legality

If you live in California, Colorado, or any CARB-mandated state, only an intake with an Executive Order (EO) number is legal for street use. The aFe Track Series CAIs we cover here carry CARB EO D-550-22 for 2017–2020 Raptors. Roush kits do not currently carry an EO for the Raptor.

Year split: 2017 vs 2018–2020

Ford updated the Raptor's intake manifold and ECU calibration for 2018, then again with the 10R80 transmission integration. The aFe 57-10010R and 57-10010D Track Series kits are validated for all four years (2017–2020) thanks to a flexible coupler design. For Roush, you must match the year: the 421981 kit covers 2015–2017 (including 2017 Raptor), and the 422089 kit covers 2018–2019 trucks. Buying the wrong-year Roush kit means coupler mismatch — we have had two customers learn this the expensive way.

Best Cold Air Intakes for 2017–2020 Ford Raptor

Below are the five intakes we sell, install, and stand behind. Each one is in stock and ships free to the lower 48.

This is the one we put on our shop truck. The carbon fiber tube is genuine pre-preg twill (not vinyl wrap), the dual Pro DRY S filters flow more than a single 6-inch element, and the sealed CNC’d top fits flush under the hood liner. Best part: zero filter oil to deal with, which matters when you wheel through Florida sugar-sand and have to clean the filter twice a season.

Same carbon tube and sealed box as the DRY S kit, but with aFe’s red-oiled five-layer cotton gauze filters. The 5R flows roughly 3–5% more CFM at peak than the dry filter, which dyno-queens love. The trade is the maintenance schedule and the — small but real — risk of over-oiling the MAF. If you are tracking this truck and care about every last horse, get the 5R. Otherwise the DRY S is the smart pick.

Roush’s 422089 kit is the pick if you want OEM-grade plastics and a quiet install. It uses a Roush-branded ProGuard 7 dry-flow filter (rated to 99% efficiency) and a sealed black ABS airbox that bolts straight to the factory mounting points. No bracket fab, no zip-tie shenanigans. Roush claims 8–12 HP gain at the wheels on a stock tune. The downside: 90-day warranty versus aFe’s lifetime.

If you have a 2017 Raptor specifically, this is the right Roush kit — not the 422089. Same sealed-airbox concept, same ProGuard 7 dry filter, but the inlet tube is sized for the 2017 intake manifold, which Ford revised slightly for 2018. Pricing also runs $40 less than the 18–19 kit. We see this on every 2017 Raptor that rolls into our Tampa shop looking for a clean factory-plus upgrade.

Under $335 and still backed by aFe’s lifetime warranty. The Quantum kit uses a single oversized 8.5-inch Pro DRY S filter inside a one-piece roto-molded box with a clear lid — you see the filter dirty before you have to clean it. You give up the dual-tube design and the carbon fiber, but on the dyno the difference between this and the Track Series is roughly 4–6 HP at peak. If you want the 80% solution at 40% of the price, this is the one.

Oiled vs Dry Filter: Pro 5R or Pro DRY S?

This is the question we get most often when a Raptor owner is staring at the Track Series box. Both filters fit the same kit. The difference is what they are made of and how you maintain them.

Bottom line: if you daily drive your Raptor, tow, or run it through any kind of dust, sand, or wet weather (hello Florida summer), the Pro DRY S is the right call. If you trailer the truck, only run it on clean pavement, and want every measurable CFM of flow, the Pro 5R has a very small edge.

Installation: What to Expect

Every kit on this list is a 60–90 minute driveway job. You do not need a lift. Here is the tool list we hand customers when they pick up the box:

• 8mm and 10mm sockets with a 3-inch and 6-inch extension
• 1/4-inch drive ratchet (a T-handle helps for the tight clamps along the firewall)
• Long T-handle Allen set (the Track Series uses 5mm Allen on the carbon tube clamps)
• Flat-head and Phillips screwdriver for the factory clip-style hose clamps
• An oil filter wrench — not for the filter, but useful for breaking the OE coupler loose if it’s glued to the turbo inlet by old PCV residue
• A clean shop rag and a 10mm drain pan if you tip the airbox forward and dump the moisture trap

The actual sequence: disconnect the battery negative terminal, unclip both MAF connectors, loosen the two hose clamps at the turbo inlets, lift the airbox lid, pull both filters and the lower box, transfer the MAF sensors into the new tubes (clock them the same way), drop the new heat shield onto the factory studs, install the new tubes, torque the clamps to 35 in-lb, reconnect MAF and battery, and let the ECU re-learn over a 10-minute drive cycle. We have done this in 47 minutes on the shop floor with a torque wrench and beer. First-timers should plan for 90.

Tuning, Warranty, and the Magnuson-Moss Act

Two questions every Raptor owner asks before buying: do I need a tune, and will this void my factory warranty?

Tune: All five intakes here are designed to run on the stock Ford calibration without throwing codes. The MAF housings are calibrated to factory voltage curves, so the ECU sees airflow values within spec. That said, to actually unlock the airflow potential, a 91 or 93-octane tune from 5 Star, Livernois, or PowerNation will pick up another 25–40 HP. We recommend a tune as a Phase 2 upgrade once you have lived with the intake for a few hundred miles.

Warranty: The Magnuson-Moss Warranty Act (15 U.S.C. § 2302) protects you. Ford cannot deny your powertrain warranty just because you installed an aftermarket cold air intake. They can only deny coverage if they prove the intake directly caused the failure — and that burden is on them, not you. In practice, dealers occasionally push back. Keep your install receipt, photos of the install, and a copy of the CARB EO certificate (for the aFe Track Series). If a dealer hassles you, escalate to Ford customer service. We have walked dozens of Tampa-area Raptor owners through this and have yet to see a legitimate denial stick.
