BLOX Racing Shorty Performance 5in Air Filter w/4in Velocity Stack and Coupler Kit

The BLOX Racing performance air filter kit features its “Shorty” 5″ height performance air filter, a composite velocity stack, and silicone hose coupler with clamps. Kits are dyno-proven to increase horsepower and torque. The dry element filter prevents any sensors from becoming soaked with oil that is normally associated with wet filter brands.

Key Features

• Shorty 5in Conical Filter: 5in flange diameter with 3.75in height captures more air volume than stock filters using multi-layer oiled cotton gauze media for dyno-proven flow gains up to 40%.
• 4in Velocity Stack: Mandrel-bent aluminum trumpet smooths incoming air turbulence reducing intake restrictions and boosting mid-range torque on B-series and D-series engines.
• Silicone Coupler Kit: Flexible 4in ID reinforced silicone adapters with stainless clamps connect to 3-4in intake pipes ensuring secure vibration-resistant mounting.
• Direct-Fit Design: Precision-engineered for Honda Civic and Integra applications eliminating fabrication for plug-and-play installation.
• Compatible with BLOX intake manifolds and 3in aluminum piping systems.
• Washable/Reusable Media: Clean with specialized filter oil after 50,000 miles to maintain peak performance without frequent replacements.
