Carbon Fiber Box Pre Filter 6-1/4in Black

The Carbon Fiber Box Pre Filter 6-1/4in Black by OUTERWEARS is an essential intake system upgrade for serious off-road and high-performance vehicle builders. This compact pre-filter wraps around your primary air filter to trap oversized dust, dirt, and debris before they reach the main filtration element—dramatically extending filter life and reducing maintenance intervals. Whether you're running desert racing builds, rock crawling rigs, or dusty trail vehicles, a quality pre-filter is non-negotiable for protecting your engine investment.

Constructed from genuine carbon fiber material, this pre-filter combines lightweight construction with superior durability and heat resistance compared to standard foam or mesh alternatives. The 6-1/4-inch diameter design fits a wide range of factory and aftermarket air box configurations, while the black finish resists UV degradation and maintains a clean appearance in any engine bay. Carbon fiber's inherent strength means it won't collapse under sustained airflow loads, maintaining structural integrity even in high-CFM intake systems. The compact 4.9 x 1.95 x 11.1-inch dimensions allow flexible mounting without interfering with typical underhood layouts.

Mechanics and off-road enthusiasts benefit most from pre-filters in high-dust environments where standard filters alone cannot handle the intake volume. Simply position the Carbon Fiber Box Pre Filter 6-1/4in Black around your existing filter element using the provided mounting hardware or adhesive strips; most installations require no modification to your air box. This universal fit works with stock and modified intake manifolds, intercoolers, and turbo systems. Weighing just 0.14 lbs, it adds negligible mass while delivering measurable improvements in filter longevity and engine protection during aggressive driving or competition use.
