• Worm gear clamp is not included
• 10 yr./1000000 Mile Warranty

The Spectre Performance 9131 Conical Air Filter is a high-flow, universal clamp-on replacement and upgrade filter engineered specifically for 3-inch (76 mm) intake tube applications. Whether you're building a custom cold air intake, replacing a worn filter on an aftermarket intake kit, or upgrading a short ram intake system, this round tapered filter delivers increased airflow over a restrictive paper element — and it arrives factory pre-oiled and ready to bolt on right out of the box.

Key Features & Benefits

• High-Flow Racing Filter Design: Engineered for increased airflow and greater performance compared to restrictive stock paper filters, making it a popular choice for performance builds and intake upgrades.
• Factory Pre-Oiled & Ready to Use: No prep work required before installation — the filter comes pre-oiled from the factory so you can install it immediately without waiting for oil to soak in.
• Universal Clamp-On Fitment: Designed to clamp directly onto any 3-inch intake tube, making it compatible with a wide range of aftermarket cold air intakes, short ram intakes, and custom intake fabrications that use a 3-inch pipe.
• Round Tapered (Conical) Shape: The conical profile maximizes filter surface area within a compact package, helping maintain strong airflow even in tighter engine bay spaces.
• Black Filter Media: The black finish gives the engine bay a clean, blacked-out look. If you prefer a different color, this same filter is also available in red, blue, and white — so you can match your build's aesthetic.
• Washable & Reusable: Unlike disposable paper filters, this Spectre filter can be cleaned and re-oiled for continued use, making it a cost-effective long-term upgrade.

Fitment

The Spectre 9131 is a universal fit filter — it does not have a vehicle-specific fitment list. It is designed to fit any intake tube or pipe with a 3-inch (76 mm) outer diameter. This makes it suitable for use with:

• Aftermarket cold air intake systems using 3-inch tubing
• Short ram intake kits with a 3-inch inlet
• Custom fabricated intake systems with 3-inch pipe
• Any application where a clamp-on conical filter with a 3-inch flange is specified

Important: Always verify your intake tube's outer diameter before ordering. This filter requires a 3-inch (76 mm) intake tube — it will not correctly fit 2.5-inch, 3.5-inch, or 4-inch tubes. If your build uses a different tube diameter, Spectre offers this conical filter in additional sizes.

Frequently Asked Questions

Q: Does this filter come ready to install, or do I need to oil it first?
A: The Spectre 9131 comes factory pre-oiled and is ready to install straight out of the packaging. No additional prep is needed before your first use.

Q: What size intake tube does this filter fit?
A: This filter is designed specifically for intake tubes with a 3-inch (76 mm) outer diameter. It clamps onto the tube using a standard hose clamp. It will not fit 2.5-inch or other diameter tubes.

Q: Is the 9131 only available in black?
A: No — while this listing is for the black version, the same Spectre conical filter in this size is also available in red, blue, and white if you prefer a different color for your intake build.

Q: Can this filter be cleaned and reused?
A: Yes. The Spectre 9131 is a washable, reusable performance air filter. When it becomes dirty over time, it can be cleaned and re-oiled rather than replaced, unlike single-use paper filters.
