Description

The BLOX Racing BXIM-00312-BK Velocity Stack is a universal 3.5-inch air trumpet designed to improve airflow entering a naturally aspirated or turbocharged induction system. Its smooth bell-mouth profile helps optimize incoming air velocity and reduce turbulence at the inlet, making it suitable for fabricated intakes, turbo inlets, custom airboxes, and dyno-oriented airflow setups. Injection-molded from glass-filled PA66 nylon, this lightweight composite design absorbs less heat than comparable metal stacks and places less stress on intake piping and mounting points. It can be used in custom R32, R33, R34, or R35 applications when a 3.5-inch connection and sufficient installation space are available.

Brand Overview

BLOX Racing is an automotive aftermarket manufacturer specializing in performance parts and accessories for import and sport-compact vehicles. Founded in 2003, the company develops products with an emphasis on balancing performance, durability, appearance and accessible pricing. BLOX Racing states that its components are designed, engineered and tested using modern manufacturing processes and materials, with production standards intended to meet or exceed comparable OEM requirements. Its expanding catalog includes intake components, throttle bodies, fuel-system parts, turbo and exhaust hardware, engine components, coilovers, suspension upgrades, drivetrain products, wheel hardware, gauges and exterior accessories. BLOX products are used across street builds, show vehicles, drag racing, road racing and drifting.

For Nissan Skyline GT-R and R35 GT-R projects, BLOX Racing offers select universal and specification-based components that may be suitable for custom performance builds. Depending on the vehicle and installation, these can include vacuum blocks, boost-control components, turbo and exhaust fabrication hardware, fittings, adapters, gauges, wheel studs, lug nuts and other supporting accessories. Because many BLOX products are universal rather than specifically engineered for the R32, R33, R34 or R35 GT-R, customers should confirm dimensions, thread sizes and installation requirements before purchasing. BLOX Racing remains a recognized option for builders seeking functional import-performance components that can support customized engine, turbo, fuel, exhaust and chassis setups.

Return shipping costs are generally the customer’s responsibility, and BLOX Racing advises allowing approximately two to four weeks for inspection and a claim decision.
