Spectre 9 x 2 Inch Air Cleaner for 5-1/8" Neck — Triple Chrome, Low-Profile Filter

Spectre Performance SPE-4770 is a 9-inch by 2-inch triple-chrome air cleaner assembly engineered to fit carburetors and TBI throttle bodies with a 5-1/8-inch neck.

Designed to pair showroom shine with reliable airflow, the Spectre SPE-4770 balances appearance, fit, and function for street rods, classic cars, and custom builds. The assembly includes a 9 x 2-inch replacement air filter element and a flat base that mounts to most carburetor and throttle-body intakes featuring a 5-1/8-inch neck diameter. Triple chrome plating gives the unit a polished look that resists corrosion while keeping the intake area tidy and finished.

Will this air cleaner fit my carburetor or throttle body?

The SPE-4770 is made for intakes with a 5-1/8-inch neck opening and accepts a 9 x 2-inch filter element. This makes it compatible with many aftermarket and OEM carburetors and TBI throttle bodies that use the same neck diameter. Measure your intake neck before ordering to confirm fitment.

• Neck diameter required: 5-1/8 inches
• Filter size included: 9 x 2 inches
• Flat base design for level mounting
• Works with both carburetors and throttle bodies

How does the SPE-4770 affect engine airflow and maintenance?

The replacement filter element is sized to provide smooth airflow for small- to mid-displacement engines used in street and show applications. Routine cleaning or replacement of the filter keeps airflow consistent and prevents debris from entering the intake. The flat base and compact 2-inch filter height keeps the intake profile low under hoods with limited clearance.

• Optimized 9 x 2-inch element for balanced airflow
• Low-profile 2-inch height for tight engine bays
• Easy to remove for cleaning or filter replacement
• Helps reduce large particle ingestion when maintained

What materials and finish does this air cleaner use?

Spectre constructed the SPE-4770 with a durable metal assembly finished in triple chrome plating for enhanced corrosion resistance and a high-gloss look. The chrome finish provides a classic mirrored appearance suited to restored and custom vehicles. Internally, the filter media is built for automotive intake service and engineered to fit the included assembly.

• Triple chrome plated exterior for shine and protection
• Metal housing with a flat base for stability
• Replaceable 9 x 2-inch filter element included
• Engineered for fit and long-term appearance

Who is this for? The Spectre Performance SPE-4770 suits car owners and builders seeking a compact, attractive air cleaner that fits a 5-1/8-inch neck—ideal for restorations, hot rods, or daily drivers where hood clearance or a low-profile look matters. It’s also a solid choice for anyone who wants a triple-chrome finish and a replaceable filter element that’s straightforward to service. If you need a larger or differently profiled cleaner for high-performance forced induction or oversized carburetors, consider checking Spectre’s broader lineup for alternate sizes and styles.
