aFe BladeRunner Hot and Cold Charge Pipe Kit, Part Number 46-20354-B, for 2017-2019 Fiat 124 Spider 1.4L Turbo

Smooth transitions in the 2-1/4 IN and 2-1/2 IN mandrel-bent aluminum tubing decrease turbulence and minimize pressure loss, increasing horsepower and torque. Not only does the wrinkle black powder-coated finish make for a stealthy look, but it also insulates the tube from engine heat and protects from corrosion. These tubes include high-quality stainless steel spring-loaded T-bolt clamps and heavy-duty 5-ply polyester reinforced silicone couplings. BladeRunner 2-1/4 IN & 2-1/2 IN Aluminum Hot and Cold Charge Pipe Kit Black FIAT 124 Spider 17-19 L4-1.4L (t)

• Includes premium stainless steel spring-loaded T-bolt clamps and 5-ply silicone couplings for an easy install and long lasting strength
• 1/8 IN NPT ports are provided for connecting sensors or water methanol injection
• Powder-coated wrinkle black for heat and corrosion resistance
• Includes 2-1/4 IN hot side and 2-1/2 IN cold side tubes
• Dyno-proven gains up to +11 HP and +14 lbs. x ft. TQ

The aFe BladeRunner Hot and Cold Charge Pipe Kit is designed for the 2017-2019 Fiat 124 Spider with the 1.4L turbocharged four-cylinder engine. Part number 46-20354-B replaces restrictive factory charge tubing with smooth, mandrel-bent aluminum tubes that improve airflow between the turbocharger, intercooler, and throttle body. The 2-1/4-inch hot-side tube and 2-1/2-inch cold-side tube help reduce turbulence and pressure loss, supporting improved throttle response and consistent boost delivery.

Dyno testing has demonstrated gains of up to 11 horsepower and 14 lb.-ft. of torque when properly installed with supporting modifications. Each tube features a wrinkle-black powder-coated finish that helps protect against corrosion while providing additional resistance to engine-bay heat. The finish also delivers a clean, understated appearance suited to performance street builds.

The kit includes heavy-duty, 5-ply polyester-reinforced silicone couplings and premium stainless steel spring-loaded T-bolt clamps for reliable connections under elevated boost pressure. Integrated 1/8-inch NPT ports allow installation of compatible sensors or water-methanol injection hardware. The components are engineered for a straightforward installation using the vehicle's existing mounting locations and connections.

What's Included: One hot-side aluminum charge tube, one cold-side aluminum charge tube, silicone couplings, stainless steel spring-loaded T-bolt clamps, and installation hardware as applicable. This product is not CARB approved and may not be legal for use on pollution-controlled vehicles in all jurisdictions. Fitment includes 2017, 2018, and 2019 Fiat 124 Spider models equipped with the 1.4L turbocharged four-cylinder engine.
