2005-2009 Ford Mustang GT 4.6L V8 Cold Air Intake
This Flashark cold air intake replaces the factory airbox and intake tube on 2005-2009 Ford Mustang GT models powered by the 4.6L 3-valve Modular V8 (S197 platform). The sealed heat shield draws cooler outside air into a black powder-coated aluminum intake tube, feeding a washable oiled cotton gauze cone filter for stronger throttle response and a deeper intake tone under acceleration. Bolt-on install using common hand tools in approximately 60 minutes — no permanent modification required.

Key Features
- Heat-shielded sealed airbox design: The closed heat shield draws outside air through a fender-well feed and isolates the filter from engine-bay heat, supporting more consistent intake charge temperatures than an open-element short-ram setup.
- Black powder-coated aluminum intake tube: Mandrel-bent aluminum piping replaces the factory restrictive tube to smooth airflow into the throttle body while resisting corrosion underhood.
- Greater airflow vs. stock tube: The larger-diameter tube and coupler are designed to reduce restriction; expect a measurable increase in airflow versus the factory 4.6L 3V intake tract (approximately +27% airflow vs. stock per in-house airflow comparison — see image).
- Washable oiled cotton gauze cone filter: Micro-cotton-gauze media traps debris while flowing more air than disposable paper elements, and is fully reusable when serviced with a clean-and-re-oil kit.
- Bolt-on install in about 60 minutes: Direct replacement for the factory airbox and intake tube using common hand tools — no cutting, drilling, or permanent modification.
- Retains factory MAF sensor location and bore: The intake tube is engineered to mount the stock mass-airflow sensor at the OEM location, so the ECU sees signals within its design envelope.
- Sportier engine sound under acceleration: Reduces the factory airbox baffling to deliver a deeper induction note at mid- to high RPM while quieting at cruise.
Who This Kit Is For
This Flashark cold air intake is built for 2005-2009 Ford Mustang GT owners with the 4.6L 3-valve Modular V8 who want a first bolt-on upgrade that delivers stronger throttle response, a deeper intake tone, and a reusable filter instead of disposable paper elements.
✓ For you if…
- You drive a 2005-2009 Mustang GT 4.6L V8 and want a heat-shielded intake that draws from outside the engine bay
- You prefer a washable cotton filter you can re-oil every ~30,000 miles over disposable paper elements
- You want a bolt-on install you can finish in about an hour with basic hand tools
- You tow, commute, or weekend-cruise and want consistent mid-range response
- You're outside California (and other CARB-adopting states) — see Compliance Notice below
✗ Not for you if…
- You drive a Mustang V6 — the 4.0L V6 uses a different intake geometry and throttle body, and this kit will not fit
- You need a guaranteed MPG gain — intake alone cannot guarantee a measurable fuel-economy improvement
- You're in California (or another CARB-adopting state) and your application requires an EO-numbered kit — see Compliance Notice below
- You plan deep-water crossings — see hydrolock note in Check Before Ordering
- You need an OEM-replacement factory airbox — see Ford Mustang Cold Air Intake Kits for stock replacement options
Check Before Ordering
Verify the following six items before you add this kit to your cart to avoid a return or an illegal-install situation:
- Vehicle match: Your vehicle is a 2005-2009 Ford Mustang GT with the 4.6L 3-valve Modular V8 (S197 platform). If your Mustang is a V6, a 2010+ (S197 facelift) GT, or a Shelby GT500 (5.4L supercharged), this kit will not fit — message us with your VIN before checkout.
- Intake form factor: This is a sealed heat-shielded cold air intake that draws outside air through a fender-well feed, not an open-element short-ram intake. Pick this style if you want cooler intake charge; pick a short-ram if you want maximum intake sound with simpler routing.
- Filter maintenance: The included cotton gauze cone filter is oiled and reusable. Plan to clean and re-oil it approximately every 25,000–35,000 miles (more often in dusty conditions). Over-oiling can contaminate the MAF sensor — follow the cleaning kit instructions.
- MAF sensor and throttle body: The intake tube is engineered to retain the factory MAF sensor at the OEM location and bore, and to match the factory throttle-body coupler. No spacer or adapter is required. After install, double-check that all clamps are fully seated to prevent an intake leak.
- Legality: This kit does not carry a CARB Executive Order (EO) number. It is not legal for sale or use in California (and other CARB-adopting states) for use on public roads. See the Compliance Notice below for the complete state list and exception conditions.
- Install space and water exposure: Bolt-on install in approximately 60 minutes using basic hand tools. The filter sits inside the engine bay inside the sealed heat shield. Avoid deep-water crossings — water ingestion past the air filter can hydrolock the 4.6L V8 and cause severe engine damage. If you ford water regularly, consider a high-mount or relocation intake.

2005-2009 Ford Mustang GT 4.6L V8 Cold Air Intake FAQs
Q1: Is this cold air intake legal in my state?
A1: This kit does not carry a CARB Executive Order (EO) number. It is Not legal for sale or use in California (and other CARB-adopting states) on pollution-controlled motor vehicles. If you live in California, Colorado, Connecticut, Delaware, Maine, Maryland, Massachusetts, New Jersey, New Mexico, New York, Oregon, Pennsylvania, Vermont, Virginia, Washington, or the District of Columbia, this kit is restricted to off-road, racing, or pre-emissions-controlled vehicles. See the Compliance Notice above for the full state list.
Q2: Will this fit my 2005-2009 Ford Mustang GT 4.6L V8?
A2: Yes — it is engineered as a direct replacement for the factory airbox and intake tube on 2005-2009 Ford Mustang GT models equipped with the 4.6L 3-valve Modular V8 (S197 platform). All model years from 2005 through 2009 share the same intake architecture and MAF sensor configuration, so the kit is interchangeable across the range.
Q3: How much horsepower and torque will this add?
A3: Expected output range for a stock 4.6L 3V V8 with this intake is approximately 5–10 hp and approximately 6–10% torque gain. Actual results vary with the vehicle's condition, supporting modifications (exhaust, throttle body, calibration), and installation quality. The included airflow data shows an approximately +27% airflow increase versus the stock tube, which translates to the throttle-response and torque-range gains above rather than peak-wheel horsepower numbers.
Q4: Will this cold air intake improve my fuel economy?
A4: MPG is dominated by driving habits; an intake alone can't guarantee a measurable fuel-economy gain. Expect the main benefit to show up as sharper throttle response and a deeper intake tone rather than a steady-state MPG change.
Q5: Will installing this intake void my factory warranty?
A5: Under the Magnuson-Moss Warranty Act, an aftermarket part cannot void your factory warranty unless it is proven to have caused the failure. This kit is designed as a direct bolt-on replacement that retains the factory MAF/IAT sensor location and the factory throttle-body coupler.
Q6: Will this intake trigger a check engine light (CEL)?
A6: A properly installed intake that retains the factory MAF sensor at the OEM location will generally keep the MAF signal within the ECU's design envelope. A CEL is most often caused by an intake leak (loosen or mis-seated clamp), a reversed MAF sensor, or an over-oiled filter media contaminating the MAF hot film. Verify each item on the install checklist before starting the engine.
Q7: Do I need an ECU tune after installing this intake?
A7: No tune is required for a basic bolt-on install that retains the factory MAF sensor location, factory bore, and factory throttle-body coupler. A custom tune is recommended only if you are also adding supporting modifications such as a higher-flow exhaust, an aftermarket throttle body, or different camshafts.
Q8: Is this intake safe in rain or deep water?
A8: Normal rain and street driving are fine — the filter is enclosed inside the sealed heat shield with an outside-air feed. Avoid deep-water crossings; water ingestion past the air filter can hydrolock the 4.6L V8 and cause severe engine damage. If you ford water regularly, consider a high-mount or relocation intake instead.
Q9: How do I clean and re-oil the filter?
A9: The oiled cotton gauze cone filter is fully reusable. Use a cotton-gauze cleaning kit: apply the cleaner to the media, let it soak, rinse with water from the clean side out, let it air-dry completely, then apply the specified filter oil evenly along each pleat. Over-oiling can contaminate the MAF sensor — apply oil sparingly. Re-service the filter approximately every 25,000–35,000 miles (more often in dusty conditions).
Q10: What does this intake sound like?
A10: You'll hear a deeper intake tone under acceleration; at cruise it quiets down. Because this is a sealed heat-shielded cold air intake (not an open-element short-ram), the volume is more moderate — you'll get the throaty 4.6L induction note without the louder cabin drone a short-ram produces.
Q11: What's included in the box, and what do I still need?
A11: The kit includes the red cotton cone filter, the black powder-coated aluminum intake tube, the sealed heat shield, a silicone coupler, four hose clamps, edge trim, mounting brackets and hardware, and installation instructions. The factory MAF and IAT sensors are reuse items transplanted from your stock airbox and are not included in the kit. You will need basic hand tools (socket set, screwdriver, pliers) and approximately 60 minutes. Browse the Ford Cold Air Intake Kits collection for replacement filters and cleaning kits.
Q12: Will this work with my aftermarket throttle body?
A12: This kit is engineered for the factory 4.6L 3V V8 throttle-body bore. If you run an oversized aftermarket throttle body, please message us with the throttle-body bore diameter before ordering so we can confirm the silicone coupler matches. For factory-spec throttle bodies, no coupler change is required.
