Spectre Universal Clamp-On Air Filter — Black reverse-tapered 3/3.5/4 in flange, washable high-flow HPR

Spectre SPE-8161 is a clamp-on, washable high-flow air filter engineered to boost airflow and protect your engine while being reusable for a lifetime. This clamp-on Spectre HPR (High Performance Racing) air filter uses non-woven synthetic media and reinforced steel mesh to allow more air through than standard paper elements, helping improve throttle response and overall engine breathing. It's designed as a round reverse-tapered filter with an easy clamp-on flange and washable construction, so you can clean and re-oil it with Spectre's AccuCharge kit to keep performance consistent over years of use.

What exact size and shape is this Spectre filter?

The SPE-8161 is a round, reverse-tapered clamp-on filter built for universal fitment. It has three flange ID options (3 in, 3.5 in, and 4 in) to match a variety of intake necks and throttle bodies.

• Overall height: 2.625 inches (67 mm)
• Base diameter: 6 inches (152 mm)
• Top diameter: 4.75 inches
• Flange inner diameters: 3.00, 3.50, or 4.00 inches

How does the washable design help me save time and money?

Because the SPE-8161 is washable and reusable, you avoid frequent disposable-filter replacements and reduce long-term maintenance costs. With normal highway driving, the filter can go about 50,000 miles before the first cleaning, and when maintained with AccuCharge cleaning and re-oiling products it stays effective for the life of your vehicle.

• Reusable for the vehicle lifetime—no regular paper filter purchases
• 50,000 miles typical interval before initial service under normal driving
• Clean and re-oil with Spectre AccuCharge kit for best performance
• Reduces long-term replacement expense versus disposable filters

Will this filter improve performance and protect my engine?

Spectre's HPR filter media is engineered to increase airflow while still trapping contaminants, helping deliver better acceleration and throttle response without sacrificing protection. The unit combines high-flow synthetic media with a urethane frame and steel mesh reinforcement for durability under road conditions.

• Up to 50% more airflow compared with many disposable paper filters
• Non-woven synthetic media for improved contaminant capture
• Durable urethane base and steel mesh for long-term strength
• Designed to balance airflow gains with engine protection

How easy is it to install and maintain the clamp-on filter?

Installation is straightforward: slide the correct flange size over your intake neck and secure with the clamp for a quick upgrade. Routine maintenance is low effort—remove, clean using Spectre AccuCharge, re-oil, and reinstall to restore peak performance.

• Clamp-on design for fast, tool-light installation
• Multiple flange IDs to fit common intake sizes without adapters
