Vibrant Performance 10931 Classic Short 4" Inlet Air Filter Red Cotton Gauze

Vehicle Fitment

• Universal - compatible with any turbo outlet, cold air intake, or short ram intake with a 4.00" O.D. inlet tube requiring a compact clamp-on conical air filter for space-constrained installations

Fitment Notes

• This is the compact "shorty" version of the Classic 4" filter - at 3-5/8" filter height and 4.25" overall height, it is significantly shorter than the standard PN 10925 (6.25" tall) and designed specifically for tight engine bay installations and direct turbo outlet fitment
• Universal clamp-on fitment - mounts to any 4.00" O.D. intake or turbo outlet tube; secure with a standard hose clamp (not included)
• For the full-size Classic 4" filter, use PN 10925; for a 4.5" shorty variant, see the corresponding shorty series SKU
• Pre-oiled and ready to install; cleaning recommended every 10,000-15,000 miles

Features

• Compact "shorty" filter height of 3-5/8" (88.9mm) makes this the ideal choice for turbo outlets and engine bays where full-height filters cannot fit without clearance issues
• 4-ply pleated cotton gauze filter element delivers significantly higher airflow than a stock paper filter while providing excellent filtration of airborne particulate
• Inverted cone end cap design promotes more efficient airflow into the filter element, reducing intake restriction versus a flat-cap design
• Washable and reusable - indefinite service life with regular cleaning, eliminating recurring filter replacement costs
• Pre-oiled at the factory for immediate use with no additional oiling required before first installation

Product Description

The Vibrant Performance CLASSIC 10931 is the compact "shorty" version of the Classic 4" conical air filter, designed specifically for turbo outlets and space-constrained engine bay installations where the full-height 10925 (6.25" tall) cannot fit. At just 3-5/8" filter height and 4.25" overall height, it provides the same 4-ply pleated cotton gauze filtration and inverted cone end cap design as the standard Classic series in a package that clears intercooler pipes, strut towers, and other underhood obstacles that would otherwise make filter fitment impossible.

The filter arrives pre-oiled and ready to install - simply clamp it onto any 4.00" O.D. intake tube or turbo outlet with a standard hose clamp. The cotton gauze element is washable and reusable with a cleaning interval of every 10,000 to 15,000 miles. For applications where filter height is not a constraint, the full-size PN 10925 offers a larger filtration surface area at the same 4.00" inlet size.
