What's Included

• aFe Momentum GT Carbon Fiber Cold Air Intake System: Designed specifically for 6.4L 392 HEMI engines from 2011–2024, this intake enhances airflow and throttle response while adding a lightweight carbon fiber construction for durability and style.
• Ripp HEMI High Performance Coil Packs: A set of eight coil packs engineered with increased windings and high-quality materials to deliver stronger spark energy, improving combustion efficiency and throttle response without requiring tuning.
• E3.74 Automotive Spark Plugs: Featuring patented DiamondFIRE technology and a triple-legged ground electrode, these spark plugs promote faster, more complete combustion for better horsepower, fuel efficiency, and long-lasting performance.

Bundle Overview

This Stage 1 Kit combines enhanced intake airflow, upgraded ignition coil packs, and advanced spark plugs to optimize combustion and engine responsiveness on the 6.4L 392 HEMI platform. The aFe Momentum GT intake system increases the volume and quality of air entering the engine, while the Ripp coil packs provide a hotter, more consistent spark to accelerate flame speed and improve cylinder pressure. Complementing these upgrades, the E3.74 spark plugs ensure efficient combustion with their unique electrode design and DiamondFIRE technology.

Together, these components work in harmony to deliver smoother throttle response, improved power delivery, and a more refined driving experience. This bundle is ideal for enthusiasts looking to unlock additional performance gains without complex modifications or tuning.

Expected Performance

The Ripp coil packs alone can add up to 25–30 wheel horsepower on the 6.4L engine by increasing spark energy and combustion efficiency. Combined with the aFe intake’s enhanced airflow and the E3 spark plugs’ optimized combustion, this kit supports noticeable improvements in throttle response and overall engine power.

Key Features

This bundle highlights several advanced features designed to maximize your 6.4L 392 HEMI’s potential:

• Lightweight carbon fiber construction on the aFe intake for durability and heat resistance
• High-density polymer and epoxy-filled coil pack housings engineered to resist heat, vibration, and chemicals
• Increased coil winding turns for higher spark energy and improved flame propagation
• Patented DiamondFIRE technology in spark plugs for faster, more complete combustion
• Direct bolt-on installation with no tuning required for coil packs and intake
• Fixed-gap spark plugs designed for consistent performance and extended service life
• Improved throttle response and smoother engine operation across the RPM range
