Spectre Universal Clamp-On Air Filter SPE-8161 — Black, Fits 3/3.5/4 in Flanges, High-Flow Washable

Spectre's Universal Clamp-On Air Filter (SPE-8161) is a washable, reusable high-flow round reverse-tapered filter designed to boost airflow and protect engines while fitting 3", 3.5" or 4" flange inlets.

This compact performance filter blends a low-profile 2.625 in (67 mm) height with a 6 in (152 mm) base and a 4.75 in top to fit tight engine bays and intake snorkels. Built with reinforced steel mesh and a durable urethane frame, it replaces disposable paper elements to deliver better throttle response and long-term savings. Routine maintenance with Spectre AccuCharge cleaning and re-oiling kits keeps the element performing like new for the life of your vehicle.

How does this filter improve engine breathing?

The SPE-8161 uses a high-efficiency synthetic media that allows substantially more air to pass through than standard paper filters, helping engines respond faster under load. The reverse-tapered round shape encourages smoother airflow into the intake, reducing restriction without sacrificing contaminant capture.

• Up to 50% greater airflow versus disposable paper filters
• Non-woven synthetic media for consistent filtration performance
• Steel mesh reinforcement maintains shape under pressure
• Reduced intake restriction for better acceleration feel

Will it fit my intake — what flange sizes and dimensions matter?

This universal clamp-on model is built to adapt: it fits 3 in, 3.5 in, and 4 in flange inner diameters for broad compatibility with many aftermarket and factory intakes. With a 2.625 in (67 mm) height, a 6 in (152 mm) base diameter and a 4.75 in top diameter, it’s a compact choice for confined installation spaces.

• Flange ID compatibility: 3.0, 3.5, 4.0 inches
• Overall height: 2.625 inches (67 mm)
• Base diameter: 6 inches (152 mm); top diameter: 4.75 inches
• Clamp-on design for quick, tool-light installation

How do I care for this washable, reusable filter?

Maintaining the Spectre SPE-8161 is straightforward: clean and re-oil using Spectre's AccuCharge kit when recommended to restore airflow and filtration efficiency. Under normal highway driving, the product is designed for low maintenance and typically requires its first cleaning around 50,000 miles, depending on conditions.

• Use Spectre AccuCharge cleaning and re-oiling kit for best results
• Recommended first cleaning around 50,000 miles in normal conditions
• Washable design reduces ongoing replacement costs and waste
• Durable materials maintain performance through many service cycles

What durability and protection features are built into this filter?

The SPE-8161 combines a robust urethane frame with a reinforced steel mesh to resist deformation and deliver consistent sealing at the intake flange. The synthetic filtration media is engineered to trap contaminants while remaining breathable, preserving performance over extended service intervals.

• Urethane frame for long-lasting sealing and shape retention
• Steel mesh reinforcement protects the media from collapsing
• High-quality synthetic media filters dirt without choking airflow
• Designed to lower lifetime filter spending by avoiding disposables

Who is this for? The Spectre SPE-8161 is aimed at enthusiasts and everyday drivers who want a compact, reusable high-flow air filter that saves money and reduces waste while improving throttle response. It suits vehicles and intake systems requiring a low-profile clamp-on solution with a 3–4 inch flange fitment—ideal for tight engine compartments, cold-air intakes, turbo inlet pipes and DIY performance upgrades. If you want a durable, washable alternative to paper filters with easy installation and reliable airflow gains, this Spectre model is a practical choice.
