Flashark Cold Air Intake Kit - 2003-2007 Ford 6.0L Powerstroke Diesel F250 F350 F450 F550 Excursion

2003–2007 Ford 6.0 Powerstroke Cold Air Intake Kit FAQs

Q1: Is this cold air intake legal in my state?

A1: This kit is sold with no CARB EO on file. In California and other CARB-adopting states, that means: Not legal for sale or use in California (and other CARB-adopting states) (CVC §27156). Most aftermarket diesel cold-air intake systems are exempt from CARB EO requirements, but exemption status is model-year- and configuration-specific — confirm with your local smog-check station or with CARB before a smog test if you live in a CARB-adopting state. In non-CARB states, no federal or state EO is required for a diesel cold-air intake of this type.

Q2: Will this fit my 2003-2007 Ford Super Duty / Excursion with the 6.0 Powerstroke?

A2: It fits exact on 2003-2007 Ford F-250 / F-350 / F-450 Super Duty, 2004-2005 F-550 Super Duty, and 2003-2005 Excursion when the engine is the 6.0L V8 Powerstroke turbo-diesel. Trucks with the 7.3L, 6.4L, or 6.7L Powerstroke are incompatible (different sensor bore and intake path); see the Fitment table for the matching kit SKU. If your VIN does not confirm the 6.0L Powerstroke (engine code P), contact us with your VIN before ordering — three of {make + model + year + engine} must match for an exact fit, otherwise fitment is unknown until verified.

Q3: How much horsepower will this add?

A3: Real-world gains on the 6.0L Powerstroke typically land in the +5 to +15 whp range, depending on the vehicle, current tune, and supporting modifications. The kit is advertised at +7-10% HP / +6-8% Torque vs the stock airbox on stock trucks; treat the percentage as a range, not a guarantee. Custom tunes, exhaust upgrades, and turbo-back modifications stack on top of intake gains.

Q4: Will a cold air intake improve my MPG?

A4: Fuel economy is dominated by driving habits, load, and terrain — an intake alone does not guarantee a measurable MPG gain. Expect the main benefits as throttle response and intake tone rather than a specific MPG number. Do not buy any intake on the promise of "more MPG" alone.

Q5: Will this void my warranty?

A5: Under the Magnuson-Moss Warranty Act, an aftermarket part cannot void your factory warranty unless the manufacturer proves that the part caused the failure in question. This kit is a direct bolt-on replacement that keeps the factory MAF and IAT sensors at their OEM locations and bores, so it stays inside the OEM calibration envelope. Keep your receipts in case any warranty claim arises.

Q6: Will this throw a check engine light (CEL)?

A6: The kit is designed to retain the factory MAF sensor at its OEM location and bore, which keeps the MAF signal inside the ECU's expected range. CELs after an intake install are usually traced to one of three causes: an intake leak at the silicone coupler (re-seat the coupler and re-tighten the clamps), an over-oiled filter (do not oil this dry cotton-gauze filter unless you have switched to a separate oiled element), or a sensor that was not reseated fully. Run a final visual check on every clamp and sensor before the first start.

Q7: Do I need a tune after installing?

A7: No. Because the kit retains the factory MAF and IAT sensors at their stock locations and bores, a bolt-on install does not require a custom tune on a stock 6.0 Powerstroke. If your truck already has a custom tune, reflash or re-learn after the install so the ECU can pick up the new airflow profile.

Q8: Is this safe in rain or deep water?

A8: Normal rain and wet-road driving are fine — the filter pulls from a heat-shielded area behind the grille. Avoid deep water crossings; water ingestion past the filter can cause hydrolock and severe engine damage on the 6.0L Powerstroke. If you regularly ford water (deep mud, snow drifts, stream crossings), consider a high-mounted or snorkel-style relocation kit rather than this engine-bay-mounted setup.

Q9: How do I clean and re-oil (or service) the dry cotton-gauze filter?

A9: This kit ships with a dry cotton-gauze filter element. Service every ~10,000-15,000 miles under typical conditions (sooner in dusty / off-road / work-site use). Use a cotton-gauze filter cleaner kit: tap off loose debris, apply the cleaner per the kit directions, rinse from the clean side out, let the element air-dry completely (do not use compressed air or direct heat), and reinstall — this filter does not require re-oiling for normal use. If you switch to an oiled cotton element later, keep oil well away from the MAF sensor — over-oiled filters are a leading cause of post-install CELs.

Q10: What does this intake sound like?

A10: You will hear a deeper intake tone under acceleration; at cruise it quiets down to a low hum. Sound is subjective — if you specifically want the loudest option, look at a short-ram (open-element with no heat shield) instead. The 6.0L Powerstroke is a diesel, so the intake note is dominated by the engine's own clatter — the kit adds intake character on top of that, not a major tonal shift.

Q11: What's included / what do I still need?

A11: The kit includes the heat shield, the 4 in powder-coated aluminum intake tube, the dry cotton-gauze conical filter, silicone coupler(s), stainless hose clamps, mounting brackets and hardware, and the install instructions. The factory MAF and IAT sensors are not included — they are reused from the stock airbox and transferred to the new tube during install. Basic hand tools (socket set, screwdriver, pliers) are required; nothing cuts or drills the truck. For more Ford Powerstroke intake options, see the Ford air intake kit collection.

Q12: Will this work with my aftermarket throttle body or turbo?

A12: The kit is engineered for the factory throttle-body bore on the 2003-2007 6.0 Powerstroke. The 6.0 Powerstroke is a turbo-diesel — the intake tube sits upstream of the turbocharger, not downstream, so aftermarket turbo inlet components do not interact with this kit. If you have installed an oversized aftermarket throttle body or a different turbo with a non-factory intake path, verify the coupler size with our support team before ordering.

Q13: How often will I need to service the filter under work-site or dusty conditions?

A13: The 10,000-15,000 mile interval assumes normal highway driving. If your truck sees construction sites, agricultural dust, off-road use, or regularly tows in dirty conditions, drop the service interval to every 3,000-5,000 miles or as needed — inspect the element visually and clean whenever the filter media looks loaded. Letting a heavily loaded filter run will hurt throttle response and over time can let debris reach the MAF sensor.

Q14: Does this work with a stock turbo and stock intercooler?

A14: Yes. The intake tube bolts in upstream of the turbocharger inlet on the 6.0 Powerstroke and feeds the stock turbo & intercooler the same way the factory airbox did. No turbo or intercooler swap is required for this kit to function — it is a direct bolt-on to the factory turbo inlet.
