aFe 46-20229-B BladeRunner Aluminum Cold-Side Intercooler Charge Pipe Black 2.5" to 2.75"

The aFe BladeRunner 46-20229-B is a cold-side intercooler charge pipe engineered to replace the restrictive factory intercooler tube on BMW N20-powered turbocharged models. Constructed from 6061-T6 billet aluminum with mandrel-bent tubing, this upgrade outflows the stock intercooler tube by up to 21%, delivering improved airflow to support increased horsepower and torque. The smooth mandrel bends minimize turbulence through the charge path, and the high-temp wrinkle-black powder-coat finish provides both heat insulation and corrosion resistance for lasting durability.

Key Features:

• 2-1/2" to 2-3/4" mandrel-bent 6061-T6 aluminum construction
• Outflows the factory intercooler tube by up to 21%
• Retains factory-style throttle body and intercooler quick-connect fittings
• High-temp wrinkle-black powder-coat finish for heat and corrosion resistance
• Heavy-duty 5-ply reinforced silicone coupling for strength and a leak-free seal
• Includes premium stainless steel clamps for a secure, leak-free installation
• Two 1/8" NPT ports for pressure sensors or water-methanol injection
• Compatible with both the factory intercooler and aFe BladeRunner intercooler
• Laser-cut aluminum aFe Power logo plate welded on for aggressive underhood style
