Product Details
Features
- White paper media restores airflow in worn or clogged filters

- Sized for 1-barrel setups — not for 2- or 4-barrel housings
Description
When a small round air-cleaner element gets dirty, restricted, or worn out, replacing it restores the airflow and filtration the assembly was designed for. This 4" round paper element is built as a direct service replacement for compatible small round air-cleaner housings, using white paper filter media to filter incoming air before it reaches the carburetor or intake.
At 4" outside diameter and 2" height, this element is sized specifically for single-barrel carburetor applications — it is not sized for 2-barrel, 4-barrel, or larger air-cleaner housings, so confirm your existing housing diameter before ordering. It's commonly used on economy and 6-cylinder engines running a factory 1-barrel carburetor, as well as restoration projects on originally 1-barrel-equipped vehicles.
This is a paper-media element, so it's a replace-only part rather than a washable one: swap it out during routine service or when the element shows visible debris loading or reduced airflow.
Applications
Fits compatible 4" round, single-barrel carburetor air-cleaner housings; commonly used on economy and 6-cylinder engines with factory 1-barrel carbs, and on restoration projects with original 1-barrel setups.
Sizing
4" outside diameter, 2" height. Not sized for 2-barrel, 4-barrel, or larger round air-cleaner housings.
