Rectangular Pre-Filter w/Top Black

The Rectangular Pre-Filter w/Top Black from OUTERWEARS is a precision air filter wrap engineered for serious engine builders and performance enthusiasts who demand maximum intake protection. This pre-filter assembly wraps around your existing air filter element, adding an extra layer of defense against dust, dirt, and debris that can compromise engine efficiency and longevity. Whether you're running a custom intake setup, modified carburetor, or fuel-injected engine with aftermarket air delivery, this rectangular pre-filter protects your investment by preventing premature filter clogging and reducing overall maintenance intervals.

Constructed from high-quality polyester material in classic black, the Rectangular Pre-Filter w/Top Black features a measured profile of 4.9 x 2 x 6.35 inches with a total length of 19 inches and 7-inch width—designed specifically for rectangular filter housings common in both street and off-road applications. The top-mounted design ensures optimal airflow while the polyester wrap effectively captures larger particulates before they reach your primary filter media, extending filter life and maintaining consistent air density for accurate engine tuning. The durable black polyester construction resists UV degradation and withstands heat cycles typical in high-performance engine bays, making it a reliable upgrade for both naturally aspirated and forced-induction builds.

This pre-filter is ideal for hot rod builders, off-road enthusiasts, and engine tuners who operate in dusty environments or high-demand driving conditions. Installation is straightforward—simply wrap it around your existing rectangular air filter element and secure it according to your intake configuration. The lightweight design at 0.08 lbs adds negligible weight while providing substantial filtration benefit, making it compatible with custom intake manifolds, street rods, and performance engine swaps where OEM filters fall short.
