aFe BladeRunner Aluminum Hot and Cold Charge Pipe Kit with Turbo Muffler Delete, Wrinkle Black, 46-20415-B

Smooth transitions in the mandrel-bent aluminum tubing decrease turbulence and minimize pressure loss, increasing horsepower and torque. The BladeRunner I/C tube kit provides a smooth transition between the turbo and the engine for lower operating temperatures and increased power. This oversized 2-1/4in OD Turbo Muffler Delete replaces the factory turbo muffler located between the turbo compressor outlet and the hot side intercooler tube. The straight through oversized design tremendously increases flow and turbocharger sound by creating a smooth transition between the turbo and intercooler tube. CNC machined from 6061-T6 aluminum then finished in red anodizing also provides superior strength and long lasting durability. This tube kit includes high-quality, stainless-steel, spring-loaded T-bolt clamps and heavy-duty, 5-ply, polyester reinforced silicone couplings for superior strength and durability. Finished in Wrinkle Black powder coating with a unique laser-etched aFe power logo for a custom look.

Upgrade the charge-air system on your turbocharged Volkswagen GTI or compatible Audi application with the aFe BladeRunner Aluminum Hot and Cold Charge Pipe Kit, Part Number 46-20415-B. Designed to replace restrictive factory plastic intercooler tubes, this kit creates smoother airflow between the turbocharger, intercooler, and engine. Mandrel-bent aluminum tubing reduces turbulence and pressure loss to support improved horsepower, torque, throttle response, and lower charge-air operating temperatures.

The kit includes an oversized, two-piece 2-1/4-inch turbo muffler delete that replaces the factory component between the turbocharger compressor outlet and the hot-side intercooler tube. Its straight-through design improves airflow and increases turbocharger sound. TIG-welded 2-1/2-inch hot-side and 2-3/4-inch cold-side tubes are CNC-finished from durable 6061-T6 aluminum, then protected with wrinkle black powder coating for resistance to heat and corrosion. The components feature a laser-etched aFe Power logo for a clean, custom appearance.

Premium stainless-steel spring-loaded T-bolt clamps and heavy-duty, five-ply polyester-reinforced silicone couplings provide secure connections and long-term durability. Integrated 1/8-inch NPT ports support sensor installation or water-methanol injection applications. Dyno testing showed gains of up to 23 horsepower and 28 lb.-ft. of torque, while the system outflows the factory tubes by 34%. The kit is engineered for a direct replacement installation on select 2015–2021 Volkswagen GTI models with the 2.0L turbocharged four-cylinder engine, along with listed Audi applications. Verify vehicle fitment before ordering.
