- Compact 8" diameter fits tight single-carb or tunnel ram setups
- 3" height for balanced airflow and filter media capacity
- Re-oil after cleaning to maintain filtration performance
Description
Unlike a disposable paper element, this 8" round filter uses red oiled cotton gauze media designed to be cleaned and reused rather than replaced at every service interval. It's built as a direct service replacement for compatible round air-cleaner housings, filtering incoming air before it reaches the carburetor or intake while supporting long-term serviceability.
At 8" outside diameter and 3" height, this is a smaller-diameter element commonly used on compact single-carburetor setups, or as an individual filter on dual-quad/tunnel ram configurations where space is limited. Confirm your neck/inlet diameter matches your carburetor before ordering, since outside diameter alone doesn't guarantee fit.
Common in street performance and restoration builds that prefer a reusable filter over disposable paper.
Applications
Fits compact single-carburetor setups and individual dual-quad/tunnel ram configurations needing a smaller-diameter round element; used in street performance and restoration builds preferring a reusable filter.
Sizing
8" outside diameter, 3" height. Confirm neck/inlet diameter matches your carburetor before ordering.

NOTES
• Material: red oiled cotton gauze — not "washable synthetic" as currently listed.
• Do not run dry (unoiled) for extended periods — filtration efficiency drops without oil.
• Smaller diameter — commonly used on compact single-carb setups or as an individual filter on dual-carb/tunnel ram applications where space is limited.
COMMON VEHICLE APPLICATIONS
Compact engine bays and smaller single-carburetor setups
Individual filters for dual-quad/tunnel ram configurations
Restoration and street performance builds preferring a reusable filter over disposable paper
Q&A
Is this filter washable and reusable?
Yes. This filter uses red oiled cotton gauze media and is designed to be cleaned, re-oiled, and reused rather than replaced like a paper filter.
What kind of setup is this filter sized for?
Its 8-inch diameter makes it a popular choice for compact single-carburetor applications or as an individual filter on dual-quad and tunnel ram setups where space is limited.
What's the neck/inlet diameter on this filter?
The neck (inlet) diameter is not specified for this listing. Verify the neck size with TSP before ordering if compatibility with your carburetor or air cleaner base is a concern.
Do I need to oil this filter after cleaning?
Yes. Re-oil the cotton gauze media after cleaning to maintain proper filtration performance. Running the filter dry for extended periods can reduce its effectiveness.
Why is the filter media red?
The filter media is pre-treated with a red-dyed filter oil. The color helps indicate that oil has been evenly applied after cleaning and re-oiling while providing effective filtration.
Do I need two of these for a dual-carb tunnel ram setup?
Yes. Dual-quad tunnel ram intake manifolds typically use one air filter per carburetor, so you'll need two filter elements for a complete setup.
