BD Diesel Killer Grid Heater Upgrade Kit

2007–2024 Dodge Ram 2500/3500 5.7L/5.9L/6.4L/6.7L Diesel

Part #: 1041520

Overview

The BD Diesel Killer Grid Heater Upgrade Kit is engineered to solve a critical weakness found in the intake grid heater electrical connection of Dodge Ram trucks equipped with 5.7L, 5.9L, 6.4L, and 6.7L diesel engines from 2007 through 2024. This flaw, particularly prevalent in the 6.7L Cummins engine, involves a small bolt and nut inside the intake that carries a high current load of 200 amps. Over time, this connection deteriorates, leading to arcing and eventual breakage. The resulting loose nut can fall into the engine, causing catastrophic damage to pistons, cylinder heads, and valves.

BD Diesel’s Killer Grid Heater Upgrade Kit eliminates this risk by redesigning the electrical circuit to remove the vulnerable bolt and nut inside the intake while maintaining the original functionality of the grid heater. This cost-effective solution preserves engine heat output without requiring tuning or compromising cold-weather performance, making it an ideal upgrade for Dodge Ram owners seeking reliability and peace of mind.

Key Features

This upgrade kit addresses a known failure point with a practical and durable solution. Key features include:

• Eliminates the problematic bolt and nut inside the intake grid heater circuit
• Maintains full stock grid heater functionality and heat output
• Prevents electrical arcing and potential engine damage
• Cost-effective alternative to expensive aftermarket solutions
• Simple, bolt-on installation with no tuning required
• Compatible with Dodge Ram 2500 and 3500 models from 2007 to 2024
• Supports multiple engine variants: 5.7L Hemi, 5.9L Diesel, 6.4L 392, and 6.7L Cummins Diesel
• Designed to perform reliably in cold climates without heat reduction

Construction & Design

The BD Diesel Killer Grid Heater Upgrade Kit is crafted with high-quality materials engineered to withstand the demanding electrical load of the intake grid heater system. By removing the original bolt and nut connection inside the intake manifold, the kit replaces it with a robust, direct electrical path that eliminates the risk of corrosion, arcing, and mechanical failure. The design preserves the OEM grid heater’s heating capacity and durability, ensuring consistent engine warm-up and emissions control during cold starts.

Every component is precision-engineered to fit seamlessly with factory parts, maintaining the integrity of the intake system and electrical connections. This thoughtful design approach ensures long-term reliability and protects your engine investment.

Installation & Fitment

Installation of the Killer Grid Heater Upgrade Kit is straightforward and user-friendly, requiring no special tools or modifications. The kit is designed for direct replacement of the existing electrical connection components within the intake grid heater circuit. It fits perfectly on Dodge Ram 2500 and 3500 trucks equipped with 5.7L Hemi, 5.9L Diesel, 6.4L 392, and 6.7L Cummins engines from model years 2007 through 2024.

Because the kit retains stock heater functionality, no engine tuning or recalibration is necessary, making it an ideal upgrade for both professional installers and DIY enthusiasts.
