BLOX Racing BXIM-00303 3" Velocity Stack Air Filter Kit Black Composite

Vehicle Fitment

Universal - compatible with any naturally aspirated or turbocharged vehicle with a 3" (76mm) intake tube or throttle body inlet. Confirm your intake tube diameter before ordering. Also available in 2.5" (BXIM-00309), 3.5" (BXIM-00311-BK), and 4" (BXIM-00310) neck sizes.

Fitment Notes

• The 3" (76mm) neck diameter fits directly onto a 3" intake tube or throttle body inlet. The silicone coupler and clamps included in the kit connect the velocity stack to the intake tubing.
• Not CARB legal - not for street use in California or other CARB-regulated states. Intended for off-road, competition, and track use where applicable.
• The dry element air filter does not require oiling - no filter oil or maintenance spray needed. Clean with compressed air or a dry filter cleaner.
• Dyno-proven to increase horsepower and torque in BLOX Racing's own testing when replacing a restrictive factory or low-quality aftermarket filter.

Features

• BLOX Racing 3" Performance Air Filter Kit - a complete short ram/cold air intake filter assembly combining a composite velocity stack, dry element high-flow air filter, and black silicone hose coupler with clamps. Designed to increase intake airflow volume and velocity compared to the factory airbox and filter, while the velocity stack's optimized bell-mouth inlet shape reduces turbulence at the filter-to-intake transition.
• PA66 glass-filled nylon composite velocity stack - injection-molded from PA66 glass-filled nylon rather than aluminum, the composite construction significantly reduces heat soak compared to metal velocity stacks. Less heat transferred to the incoming charge air results in a denser air charge and better combustion efficiency, particularly in high underhood-temperature environments.
• Dry element air filter - does not use filter oil, eliminating the risk of oil contamination on MAF sensors or other air measurement devices downstream. The dry element design provides high filtration efficiency and is cleaned with compressed air rather than re-oiled.
• 6" outer diameter filter - provides a large filter surface area for maximum airflow capacity relative to the 3" neck, minimizing restriction across the filter element.
• Black silicone hose coupler with clamps included - provides a secure, airtight connection between the velocity stack and the intake tubing. Silicone resists underhood heat and remains flexible over a wide temperature range.
• Ideal for naturally aspirated and turbocharged applications.

Product Description

The BLOX Racing BXIM-00303 is a 3" performance air filter kit combining a PA66 glass-filled nylon composite velocity stack, dry element air filter, and black silicone coupler with clamps - everything needed to replace a factory airbox or upgrade a short ram intake filter assembly on any vehicle with a 3" intake tube or throttle body inlet. The composite velocity stack's injection-molded nylon construction reduces heat soak relative to aluminum alternatives, keeping incoming charge air cooler and denser for improved combustion efficiency.

The dry element filter requires no filter oil, eliminating the risk of MAF sensor contamination common with oiled filters. The 6" outer diameter provides a generous filter surface area to maximize airflow capacity with minimal restriction. BLOX Racing's testing shows dyno-proven horsepower and torque gains over restrictive OEM and budget aftermarket filter setups. The kit is compatible with both naturally aspirated and turbocharged applications. Not CARB legal - not for street use in California. Additional neck diameter options are available: 2.5" (BXIM-00309), 3.5" (BXIM-00311-BK), and 4" (BXIM-00310).
