2001 Honda Accord Cold Air Intake Kit for the 2.3L F23
This heat-shield cold air intake kit replaces the factory airbox and upstream intake tubing with aluminum piping and a reusable cone filter for the listed 2.3L Accord and 2.2L Prelude applications. It is designed for a deeper intake tone, stronger low- and mid-RPM throttle response, and a reusable filtration setup. Choose the air-intake-only SKU FLIS08758 or the separate header-and-intake bundle.

Key Features
- Performance-focused intake path: The kit is designed to draw cooler air through a less restrictive upstream path while retaining the stock intake manifold downstream.
- Low- and mid-RPM response: The intake is intended to sharpen throttle response through the low- and mid-RPM range.
- Deeper induction sound: The cone-filter design is intended to create a more pronounced sporty intake tone under acceleration.
- Expected output range: Approximately 7–10% more horsepower and 6–8% more torque; results vary with engine condition, calibration, installation, ambient temperature, and supporting hardware.
- Lightweight aluminum piping: The aluminum intake tube provides the published metal-pipe configuration without changing the downstream throttle body or intake manifold.
- Washable cone filter: The reusable red cone filter reduces reliance on disposable replacement elements.
- Oiled cotton media: Dual-layer pleated cotton and filter oil are intended to trap dirt and dust; use the correct cleaner and avoid excess oil during service.
- Long service interval: Approximately 100,000 miles between cleanings, with more frequent inspection and service in dusty, wet, or construction-heavy conditions.
- Simple-tool installation: The kit is intended for installation with common hand tools, with careful hose, clamp, bracket, and clearance checks before startup.
- Mounting accessories included: The intake is supplied with the mounting accessories shown for the selected option; inspect older factory hoses and clamps before removing the original system.

Check Before Ordering
- Vehicle: Match the year, model, trim, and engine to the Fitment table. A 2003 Honda Accord cold air intake application is outside this kit's listed range.
- Variant: Select FLIS08758 for the air intake kit or FLES08035-IS08758 for the exhaust-header-and-intake bundle.
- Finish: Confirm the intake-tube finish shown for your selected option before ordering.
- Factory connections: Compare the breather or vacuum hoses, sensor provisions, couplers, brackets, battery clearance, wiring, and throttle-body connection with your vehicle before removing stock parts.
- Filter service: Inspect the filter periodically, clean it with products intended for reusable cotton filters, let it air-dry completely, and apply filter oil evenly without over-oiling. See the cold air intake filter cleaning guide.
- Water exposure: Keep factory splash shields and fender liners in place. Avoid deep puddles, flooded roads, and direct pressure-washing around the filter because water ingestion can cause hydrolock and severe engine damage.
- Emissions: Confirm state and local requirements before purchase. Read the cold air intake benefits and risks guide for additional installation and water-ingestion considerations.

1998–2002 Honda Accord 2.3L Cold Air Intake FAQs
Q1: Is this cold air intake legal in my state?
A1: Not legal for sale or use in California (and other CARB-adopting states). Check current state and local emissions requirements before ordering or installing the kit.
Q2: Will this kit fit a 1998, 1999, 2000, 2001, or 2002 Honda Accord?
A2: Yes, for DX, LX, EX, SE, and VP models equipped with the 2.3L F23 inline-four. This includes the listed 2000 Honda Accord cold air intake and 2002 Honda Accord cold air intake applications; verify the engine before ordering if the car has been swapped or was sold outside the United States.
Q3: Does this fit a 3.0L V6 or a 2003 Honda Accord?
A3: No for the 1998–2002 3.0L V6. A 2003 or “03 Honda Accord cold air intake” application is outside the verified range for this kit, so contact support to confirm a different product before ordering.
Q4: Will this kit fit a Honda Prelude or an F20B6-equipped Accord?
A4: The verified Prelude fitment is 1997–2001 Base and Type SH models with the 2.2L H22 engine. F20B6 applications, non-U.S. Accords, and engine-swapped vehicles require connection, routing, and clearance verification before ordering.
Q5: Is this a 2002 Honda Accord intake manifold?
A5: No. This is a cold air intake kit that replaces the factory airbox and upstream intake tubing; the throttle body, intake plenum, intake manifold, cylinder head, and valves remain downstream and are not replaced by this kit.
Q6: How much horsepower and torque will this intake add?
A6: The expected output range is approximately 7–10% more horsepower and 6–8% more torque. Actual results depend on engine condition, ambient temperature, calibration, installation, exhaust configuration, and other supporting hardware.
Q7: What difference will I notice after installation?
A7: The intended changes are a deeper intake tone under acceleration, sharper throttle response, and a less restricted feel through the low- and mid-RPM range. Intake sound is usually less noticeable during light cruising and more pronounced as the throttle opens.
Q8: Will a cold air intake improve my MPG?
A8: 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.
Q9: Does this intake require a tune or guarantee no check engine light?
A9: Do not treat this kit as a no-CEL guarantee. After installation, allow the engine to idle and check every hose, coupler, clamp, and factory connection; a leak, loose connection, contaminated sensor, or mismatched provision can cause rough running or a diagnostic code. Read the code and correct the cause instead of simply clearing it.
Q10: Does the kit include the parts needed for installation?
A10: The intake option includes aluminum piping, the red washable cone filter, and the mounting accessories supplied for that option. Installation uses common hand tools, but inspect older factory hoses and clamps for cracks or brittleness before removing the stock airbox and resonator.
Q11: Will it fit both automatic and manual Accord models?
A11: Yes, for the listed 1998–2002 Accord trims with the 2.3L F23 engine. Fitment still depends on the original engine configuration, underhood routing, and connections matching the product.
Q12: Can I drive in rain and use this intake on a daily-driven Accord?
A12: Normal rain driving requires secure routing with the factory splash shields and fender liners in place. Avoid deep puddles, flooded roads, missing splash protection, and direct pressure-washing around the filter because water ingestion can cause hydrolock and severe engine damage.
Q13: How do I maintain the washable and reusable filter?
A13: Inspect the pleats periodically and service the filter when dirt begins to restrict them. Use a cleaner intended for reusable cotton filters, let the filter air-dry completely, and apply the correct amount of filter oil; service it more often in dusty, wet, or construction-heavy conditions. The service interval is approximately 100,000 miles between cleanings under suitable conditions.
Q14: Can I use this intake with an aftermarket exhaust header?
A14: This product offers a separate header-and-intake bundle under SKU FLES08035-IS08758. Intake and exhaust changes affect opposite sides of the airflow path, and their expected gains should not be added together because results depend on the complete vehicle setup.
Q15: Can the factory intake be reinstalled later?
A15: Yes, when the original airbox, resonator, tubing, brackets, bolts, and hoses are retained and remain serviceable. Store the original parts together in a clean, dry location if you may return the car to stock for resale, troubleshooting, emissions inspection, or wet-weather use.
