Flashark Cold Air Intake Kit for 2001–2005 Honda Civic DX/EX/LX/GX/HX/Si 1.7L 2.0L I4

Your 7th-gen Civic has two problems: a factory intake that chokes the 1.7L D17 or 2.0L K20 at high RPM, and a single-pipe aftermarket option that leaves you choosing between cold-air reach and throttle response. This Flashark kit solves both.

The dual-pipe design gives you two ways to run the intake — long-ram for true cold-air routing that draws from outside the engine bay, or short-ram for instant throttle response and easier maintenance access. Both configurations use the same mandrel-bent Φ63 mm aluminum tubes finished in matte black powder coat and the same high-flow red dry cotton gauze filter.

Everything bolts on with basic hand tools. No tune required for naturally aspirated 1.7L or 2.0L engines. Most owners finish the install in under an hour.

Key Features

• Dual-Pipe Aluminum Intake System — Two mandrel-bent Φ63 mm tubes in matte black powder coat. Run a long-ram for cold-air performance or a short-ram for instant response
• High-Flow Dry Cotton Gauze Filter — Red conical filter, top OD 120 mm / bottom OD 155 mm / 63 mm inlet. Washable, reusable, never needs oiling
• Configurable Long-Ram or Short-Ram Layout — Same kit, two setups. Long ram pulls cooler outside air; short ram places the filter in the engine bay for maximum airflow velocity
• Complete Hardware Kit — 2× straight rubber couplers (D63 × 64 mm), breather hose (D22-d15 × 163 mm), 4× stainless hose clamps, aluminum mounting bracket, M6 rubber vibration damper, washer, lock nut, and rubber grommets

• No Check Engine Light — Maintains correct MAF sensor positioning and factory breather hose routing on naturally aspirated 1.7L and 2.0L engines
• Massive Memorial Day Savings — $96.00vs\mathrm{.}$149.99 regular price. Free shipping on qualifying orders.

FAQ

Q: What is the difference between Long Ram and Short Ram?
A: Long Ram routes the filter outside the engine bay for cooler intake temperatures — ideal for highway driving and sustained high-RPM use. Short Ram keeps the filter inside the engine bay for maximum airflow velocity and quicker throttle response. This kit includes both tubes so you can switch configurations.

Q: Will this fit my 2003 Civic LX with the 1.7L automatic?
A: Yes. This kit is confirmed compatible with all 2001–2005 Civic DX/EX/LX/GX/HX automatic models with the D17 series engine. The bracket bolts to the factory mounting point behind the headlight.

Q: Does the Si (K20A3) version fit the hatchback?
A: Yes, the 2002–2005 Civic Si 3-door hatchback with the 2.0L K20A3 is supported. Use the long-ram configuration for best results.

Q: Do I need a tune after installing this intake?
A: No. On naturally aspirated D17 and K20A3 engines, the intake works safely with the factory ECU. Most owners report no CEL and immediate seat-of-the-pants gains.

Q: Is the filter oiled or dry?
A: Dry. The red conical filter is dry cotton gauze — no oiling required, ever. Clean it with mild soap and water when dirty.

Q: What tools do I need for installation?
A: 10 mm and 12 mm sockets, flat-head screwdriver, and pliers. Everything else is included in the kit.
