aFe BladeRunner 3" Intercooler Hot & Cold Charge Pipe Kit Jeep Wrangler JL Gladiator JT 3.0L EcoDiesel | 46-20434-B

Overview

The aFe Power BladeRunner 3" Aluminum Hot & Cold Charge Pipe Kit (Part #46-20434-B) is a direct OEM replacement for the restrictive factory plastic and rubber intercooler tubes on the 2020–2023 Jeep Wrangler JL and 2021–2023 Jeep Gladiator JT equipped with the 3.0L EcoDiesel V6. Engineered for EcoDiesel enthusiasts who demand more from their turbocharging system, this USA-assembled kit delivers dyno-proven performance gains, premium hardware, and a clean custom look — all with a bolt-on installation using factory mounting points. Whether you're hitting the trails or hauling on the highway, these BladeRunner pipes keep charged air cooler, cleaner, and flowing stronger than stock.

Key Features & Benefits

• Up to +20% Airflow Increase – Mandrel-bent aluminum tubing eliminates the tight bends and restrictive geometry of the stock plastic pipes, dramatically improving turbo-to-engine airflow efficiency.
• Dyno-Proven Performance Gains – Verified gains of up to +5 HP and +10 lb-ft of torque over factory intercooler tubes, with improved throttle response and turbo spool.
• TIG-Welded Aluminum Construction – 2-1/2" hot side and 2-3/4" cold side tubes are TIG-welded for superior structural integrity, heat resistance, and long-term durability over factory rubber and plastic components.
• Factory-Style Billet Quick-Connect Adapters – OEM-style billet aluminum quick-connect adapters with O-ring seals ensure a leak-free, rattle-free fit while maintaining factory-level strength and durability.
• Premium Stainless-Steel SmartSeal Clamps – Spring-loaded T-bolt clamps combined with heavy-duty 5-ply polyester-reinforced silicone couplings provide a secure, vibration-resistant seal that won't loosen under boost.
• 1/8" NPT Sensor Ports – Built-in 1/8" NPT ports on both the hot and cold side pipes allow easy connection of boost sensors, pyrometers, or water-methanol injection fittings — no drilling required.
• Wrinkle Black Powder Coat Finish – A heat- and corrosion-resistant wrinkle black powdercoat finish protects the aluminum from engine bay heat and moisture. Completed with a laser-etched aFe Power logo for a custom, aggressive underhood appearance.
• Lower Operating Temperatures – By eliminating pressure loss between the turbocharger and engine, these pipes reduce heat soak and help lower EGTs (Exhaust Gas Temperatures), protecting your EcoDiesel under sustained load.
• Eliminates Factory Hot-Side Muffler – Unlike the stock hot side pipe, the BladeRunner design removes the internal factory muffler restriction for even freer airflow.
• Assembled in the USA – Manufactured and assembled in Corona, California by aFe Power.

Installation

The aFe BladeRunner charge pipe kit is rated as a Skill Level 2 (Intermediate) installation with an estimated completion time of under 1 hour for most installers (real-world installs on EcoDiesel JL/JT models have ranged from 1–2 hours depending on experience and tool access). The kit utilizes all factory mounting locations and OEM-style quick-connect adapters — no cutting, drilling, or permanent modification is required. All necessary hardware is included. Professional installation is recommended if you are unfamiliar with turbocharged intercooler systems. Tip: Lubricate the O-rings with grease prior to installation to prevent tearing. Apply thread sealant to any sensors reinstalled into the 1/8" NPT ports.
