3.5" Intake Manifold with Heating Element for 2007-2024 Dodge Ram 2500/3500 6.7L Diesel | SPELAB

3.5 inches Intake Manifold with Heating Element Description

Unleash the true potential of your 6.7L Dodge Ram without compromise. Stock intake manifolds are designed to be restrictive, and while many aftermarket "grid heater delete" systems improve airflow, they sacrifice crucial cold-weather starting performance. The SPELAB 3.5" Performance Intake Manifold is the ultimate all-in-one solution, engineered for the Dodge Ram owner who demands maximum power and all-season reliability.

By integrating a high-efficiency heating element directly into our high-flow, stainless steel manifold, we've eliminated the need to choose between performance gains and dependable cold starts. This system is designed to significantly increase airflow to your engine, resulting in faster turbo spool, increased horsepower, greater torque, and improved throttle response. Dominate cold mornings and demanding workloads with an engine that breathes better and starts stronger, every time.

Note: If installing this manifold with a Grid Heater Delete Plate, an IAT Sensor Extension Harness is required. The factory wiring is too short for the new sensor position. Ensure a perfect, plug-and-play fit by adding the harness to your order.

Fitment

• 2007-2024 Dodge Ram 2500/3500 6.7L Diesel, doesn't fit cab and chassis.

Note for 2019-2024 Models:
Due to the routing of the factory fuel line on 2019+ models, interference may occur with the intake manifold. To resolve this, we include a specialized replacement fuel line when you select the "2019-2024" option.

Intake Manifold Key Features （with Heating Element）

• Integrated High-Efficiency Heating Element
  Provides reliable, fast startups in cold climates, reducing engine wear and eliminating the excessive white smoke associated with cold diesel engines. Say goodbye to the performance compromise of a grid heater delete.
• Massive 3.5" High-Flow Design
  Mandrel-bent stainless steel construction dramatically increases airflow compared to the restrictive stock manifold. This results in quicker turbo spool, lower EGTs (Exhaust Gas Temperatures), and significant gains in horsepower and torque.
  
• Superior Durability & Construction
  Fabricated from premium stainless steel for exceptional strength, corrosion resistance, and heat dissipation. Precision TIG welding ensures a leak-proof seal and long-lasting performance under the most demanding conditions.
  
• Direct Bolt-On Installation
  Engineered to utilize factory mounting points for a straightforward installation. The kit includes multiple NPT ports for easy connection of boost gauges, sensors, or water-methanol injection systems.

Prevent the Notorious Grid Heater Bolt Failure

The factory grid heater design on the 6.7L Dodge Ram engine poses a significant, well-documented risk. The retaining bolt and nut for the heating element are known to eventually fail, break off, and drop directly into the intake, leading to catastrophic and costly internal engine damage. Our performance manifold completely eliminates this factory weak point. By integrating a robust, bolt-free heating coil, we provide a permanent solution that protects your investment and delivers total peace of mind.

Modern, High-Efficiency Heating Solution

Say goodbye to the restrictive and failure-prone factory grid heater. Our manifold features a state-of-the-art, integrated heating coil that delivers fast, reliable, and efficient heating for smooth cold starts in any climate. This advanced design not only ensures your engine fires up effortlessly in frigid conditions but also removes a major source of airflow obstruction, paving the way for significant performance gains that the stock setup could never achieve.

Ensure Balanced, Uniform Cylinder Airflow

The stock intake manifold suffers from a flawed design that causes uneven air distribution, starving some cylinders while over-feeding others. This imbalance compromises efficiency and robs your engine of power. Our manifold is engineered with superior fluid dynamics, featuring a high-flow plenum that guarantees uniform and pressurized airflow is delivered equally to every cylinder. This optimized distribution unlocks smoother engine operation, a broader powerband, and maximum combustion efficiency.

Stop Performance-Robbing Carbon Deposits

The stock intake is a magnet for performance-killing carbon buildup from the EGR system, which clogs passages and chokes your engine over time. This leads to a gradual loss of power, poor throttle response, and decreased fuel economy. Our smooth-wall, high-flow stainless steel manifold is designed to minimize carbon accumulation. Its streamlined interior surface resists deposit formation, ensuring your engine breathes clean and maintains peak performance for years to come.

FAQ

Q: What are the main benefits of installing this intake manifold?

A: The primary benefits are twofold: a significant increase in airflow for better performance (horsepower, torque, throttle response) and improved cold-weather starting thanks to the integrated heating coil.

Q: How does the integrated heating coil work?

A: Similar to a factory grid heater, the coil warms the incoming air before it enters the combustion chamber. This is crucial for diesel engines in cold climates, as it aids in ignition, leading to faster, smoother starts and reduced white smoke.

Q: Will I need to retune my truck's ECU after installation?

A: While a custom tune is not required for installation and you will see benefits on a stock truck, a custom ECU tune will maximize the performance gains from the increased airflow.

Q: Is this product difficult to install?

A: Installation is straightforward for individuals with moderate mechanical experience. It is a direct bolt-on replacement for the factory manifold and utilizes stock mounting locations. We recommend professional installation if you are not comfortable working on your engine.

Q: Does this manifold replace the factory grid heater?

A: Yes, this is an all-in-one solution. The integrated heating element replaces the stock grid heater, which is known to be a point of airflow restriction.

Q: What is the advantage of stainless steel over cast aluminum?

A: Stainless steel offers excellent strength and superior corrosion resistance compared to many cast aluminum alternatives, ensuring long-lasting durability and performance, especially in harsh weather conditions.

Q: Can I use the auxiliary ports for my gauges?

A: Absolutely. The four 1/8" NPT ports are perfect for connecting a variety of sensors, such as a boost gauge or a pyrometer (EGT gauge), allowing you to monitor your engine's performance accurately.

Q: Will this fit with my stock intercooler piping?

A: Yes, this intake manifold is designed to be compatible with the factory intercooler piping. For even greater performance, consider upgrading to a 3.5" high-flow intercooler pipe.

Q: How does this improve fuel economy?

A: By increasing the engine's breathing efficiency, the manifold allows the engine to produce power with less effort. This can lead to improved MPG during normal driving conditions, although results will vary based on driving style.

Q: Is all necessary hardware included for installation?

A: Yes, the kit includes the intake manifold with the pre-installed heating coil, a new OEM-quality gasket, and the necessary port plugs for a complete installation.
