2002–2007 Subaru Impreza WRX 2.0L / 2.5L Turbo Cold Air Intake Kit
This cold air intake kit replaces the entire restrictive factory airbox and corrugated intake tube on your 2002–2007 Subaru Impreza WRX (GD Sedan / GG Wagon) with the EJ205 2.0L turbo (2002–2005) or the EJ255 2.5L turbo (2006–2007). The 3.0-inch mandrel-bent aluminum tube and oversized dry cone filter are positioned in the passenger-side fender well, drawing cooler, denser air from outside the engine bay. Faster turbo spool, sharper throttle response, and a deeper induction growl under boost — without touching your factory MAF sensor, blowing the air without any check engine light, or making any permanent modifications.

Key Features
- 3.0-inch mandrel-bent aluminum intake tube: Replaces the factory-corrugated rubber inlet hose with smooth internal walls and a 76 mm outer cross-section, reducing airflow turbulence before the turbo inlet. Black powder-coated finish for heat resistance (rated to 400°F / 204°C) and corrosion protection.
- High-flow dry cone filter: Large surface area conical filter with synthetic dry cotton gauze media that requires no oiling — eliminates the risk of MAF sensor contamination that is common with oiled filters on turbo Subaru applications. Washable and reusable.
- True cold air intake placement: The filter is mounted in the passenger-side fender well, isolated from engine bay heat. Cooler, denser intake charge means more oxygen per cycle, supporting more consistent power delivery on a turbocharged engine.
- Complete bolt-on kit, no permanent mods: Includes 4-ply reinforced silicone couplers, stainless steel T-bolt clamps, vehicle-specific mounting brackets, MAF adapter plate, and breather hose. Reuses your factory MAF sensor and air temperature sensor — unbolt and transfer. Returns to stock in under an hour.
- Faster spool and sharper throttle response: Removing the restrictive factory snorkel and airbox lets the turbocharger draw air with less resistance, with the most noticeable improvement in 2nd–4th gear pulls. Typical intake-only gains are approximately 8–15 WHP and 8–12 lb-ft of torque on a properly tuned WRX; actual results depend on the vehicle, calibration, installation, and supporting hardware.
- Aggressive induction sound: A more pronounced turbo spool whistle, a crisper bypass valve (BOV) release on lift-off, and a deeper intake growl under boost — unlocking the sounds your WRX turbo has been making all along, just muted by the factory airbox.
- Direct fit for GD / GG chassis: Designed to mount using existing factory bolt holes and grommets on the 2002–2007 WRX Sedan (GD) and Wagon (GG). No cutting, no drilling, no additional parts required for the standard install.
Who This Kit Is For
This Flashark Cold Air Intake is for owners of a 2002–2007 Subaru Impreza WRX Sedan (GD) or Wagon (GG) running the EJ205 2.0L turbo (2002–2005) or EJ255 2.5L turbo (2006–2007) who want faster turbo spool, sharper throttle response, a more aggressive induction note, and a washable filter — all in a bolt-on install with hand tools.
✓ For you if… you daily-drive or weekend-drive your GD/GG WRX and want a first turbo-side upgrade · you prefer a washable dry filter over disposable paper elements · you've confirmed your county or state emissions rules below before ordering · you plan to pair the intake with an appropriate tune for the MAF change.
✗ Not for you if… you have a WRX STI (different MAF housing, turbo, and manifold — see FAQ Q13) · you have a non-turbo 2.5 RS or 2.5i (this kit is for the EJ205 / EJ255 turbocharged WRX only) · you expect a guaranteed MPG gain · you live in California or another CARB-adopting state and this SKU carries no EO (see Compliance Notice) · you regularly ford deep standing water — the filter sits low in the fender well.
Check Before Ordering
- Vehicle — exact fit. Confirm your WRX is a 2002–2007 Impreza WRX Sedan (GD) or Wagon (GG) with the EJ205 2.0L turbo (2002–2005) or EJ255 2.5L turbo (2006–2007). This kit does not fit the WRX STI (different MAF housing, turbo, and manifold) and is not compatible with non-turbo 2.5 RS or 2.5i models. If your vehicle is not on the Fitment table, message us with the year, model, trim, and engine code before ordering.
- Intake type — sealed cold air, not a short ram. This is a true cold air intake: the cone filter sits in the passenger-side fender well, isolated from engine bay heat. It is not a short ram / open-element intake that pulls hot engine bay air. If you want the simplest install or the loudest intake note, consider a short ram style instead.
- Filter care — dry media, no oil. The filter is dry synthetic cotton gauze. Do not oil it; oil can transfer to the MAF sensor element and cause fuel trim drift on turbo Subaru applications. Clean and re-use per the cleaning kit instructions — no oil is required.
- Sensors and tune — keep the MAF, plan a tune. The kit reuses the factory MAF sensor and air temperature sensor at their OEM location and bore, and is designed as a bolt-on replacement. Subaru turbo engines rely on the MAF to calculate fuel delivery, so an appropriate tune (Cobb Accessport Stage 1+ map or open-source ECU flash for an aftermarket intake) is strongly recommended to keep the air-fuel ratio safe under boost.
- Legality — no CARB EO. This kit does not carry a CARB Executive Order. Not legal for sale or use in California (and other CARB-adopting states). If you live in a CARB state, do not order this kit for street use.
- Install space and water crossings. Filter mounts low in the passenger-side fender well. Avoid deep standing water; water ingestion can cause hydrolock and severe engine damage. Normal rain and wet-road driving are fine. Budget 60–90 minutes and basic hand tools; no cutting or permanent modification is required.

2002–2007 Subaru Impreza WRX 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). It is not legal for sale or use in California (and other CARB-adopting states). For street use in a CARB state, choose an EO-stamped cold air intake variant. Outside of states, confirm your local inspection and emissions rules before installing.
Q2: Will this fit my 2002–2007 Subaru Impreza WRX?
A2: This kit fits the 2002–2007 USDM Subaru Impreza WRX Sedan (GD chassis) and Wagon (GG chassis) with the factory EJ205 2.0L turbo (2002–2005) or the EJ255 2.5L turbo (2006–2007). It is designed around the WRX MAF housing and intake routing. It does not fit the WRX STI, the non-turbo 2.5 RS or 2.5i, or any other Subaru model outside the Fitment table. If your vehicle is not listed, message us with the year, model, trim, and engine code before ordering.
Q3: How much horsepower will this add?
A3: Typical intake-only gains for this application are approximately 8–15 WHP and 8–12 lb-ft of torque on a properly tuned WRX. The most noticeable improvement is not the peak number but the area under the curve — faster turbo spool, sharper throttle response, and more consistent power delivery across the mid-range. Actual results depend on the vehicle, calibration, installation, and supporting hardware (downpipe, exhaust, tune). Claims of 20+ WHP from an intake alone on a stock-turbo WRX are unrealistic — be skeptical of inflated marketing numbers.
Q4: Will a cold air intake improve my MPG?
A4: MPG is dominated by driving habits; an intake alone can't guarantee a measurable gain. Expect the main benefit as throttle response and intake tone rather than fuel economy. The more responsive throttle and aggressive intake sound tend to encourage spirited driving, which can offset any real-world fuel savings.
Q5: Will this void my 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 keeps factory sensors and connections in their OEM location.
Q6: Will it throw a check engine light (CEL)?
A6: When installed correctly and paired with an appropriate tune, no. A CEL after intake installation on a Subaru is typically caused by an air leak at a coupler or MAF flange, the MAF sensor installed backward or clocked incorrectly, or fuel trims drifting outside the expected range because no tune was applied. Double-check all clamp connections and MAF orientation before starting the engine.
Q7: Do I need a tune after installing?
A7: Yes — strongly recommended. Subaru turbo engines rely on the MAF sensor to calculate fuel delivery. When you change the intake tube diameter and airflow characteristics, the MAF scaling changes. Running without a tune can result in a lean air-fuel ratio under boost, which can cause detonation and engine damage. An off-the-shelf Cobb Accessport Stage 1+ map or an open-source ECU flash tuned for an aftermarket intake is the safe minimum.
Q8: Is this safe in rain or deep water?
A8: Normal rain driving is fine — the filter pulls from the passenger-side fender well, protected by the fender liner and bumper cover. Avoid deep water crossings; water ingestion can cause hydrolock and severe engine damage. Consider a high-mounted or relocation filter if you ford water regularly.
Q9: How do I clean the filter?
A9: The filter is dry synthetic media — it does not require oiling, and oil should never be applied. Clean with a dry-filter cleaning kit per the kit instructions, allow the filter to dry fully, and reinstall. Over-oiling is not a factor with this filter, which eliminates the MAF contamination risk that oiled filters can introduce on turbo Subaru applications.
Q10: What does it sound like?
A10: You will hear a more pronounced turbo spool whistle (the "whoosh" as the turbo builds boost), a crisper bypass valve release on throttle lift, and a deeper induction growl under wide-open throttle. The sound is significantly more aggressive than stock but not obnoxiously loud at cruise — think of it as unlocking the sounds your WRX turbo has been making all along, just muted by the factory airbox.
Q11: What's included, and what do I still need?
A11: The kit includes the 3.0-inch aluminum intake tube, dry cone filter, 4-ply silicone couplers, three stainless steel T-bolt clamps, a vehicle-specific mounting bracket with hardware, MAF adapter plate, breather hose, and an installation instruction sheet. Your factory MAF sensor and air temperature sensor are reused — unbolt and transfer. You will also need basic hand tools and approximately 60–90 minutes. A matching tune (Cobb Accessport Stage 1+ map or equivalent) is strongly recommended for the EJ205 / EJ255.
Q12: Does this fit a WRX STI, 2.5 RS, or 2.5i?
A12: No. The WRX STI uses a different MAF housing diameter, a different turbocharger (VF39 / VF43 vs TD04 / VF52 on the WRX), and a different intake manifold design — installing this kit on an STI would produce incorrect MAF scaling and potential engine damage without a custom tune. The non-turbo 2.5 RS and 2.5i use a different intake system entirely; this kit is designed for the EJ205 / EJ255 turbocharged WRX only. Use an STI-specific intake on the STI, and a non-turbo-specific intake on the 2.5 RS or 2.5i.
Q13: Will this work with my aftermarket intercooler, BOV, or turbo inlet?
A13: It depends on the specific combination. This kit is designed to work with the factory top-mount intercooler, factory bypass valve, and factory turbo inlet. Aftermarket turbo inlets, front-mount intercooler piping, aftermarket blow-off valves, and strut tower braces may interfere with one another depending on their design and routing. If you have multiple aftermarket parts in the engine bay, check clearance with our support team before ordering.
