Three Signature Intake Manifolds for Every Driving Style
SPELAB offers three distinct intake horn solutions tailored for the Dodge Ram 6.7L diesel engine. From high-flow performance upgrades to structurally optimized intake horns, and even all-in-one kits that help address cold start and carbon buildup concerns, each product is designed around a different set of performance goals. Whether you're towing heavy loads, building a more responsive daily driver, or looking for a complete Dodge Ram 6.7L diesel intake manifold upgrade, there is a SPELAB solution built for your setup.
1. 3.5'' Intake Manifold for Dodge Ram 6.7L Diesel (2007–2018)
This Dodge Ram 6.7L diesel intake horn is built for serious airflow. Featuring a 3.5-inch unobstructed inlet feeding into two 3-inch mandrel-bent tubes, it is designed to drastically improve air volume and help support higher horsepower and torque. It is an excellent choice for off-road builds, heavy-duty towing, and truck owners who want more consistent performance under pressure.
Equipped with two NPT sensor ports in its performance-oriented design, this setup can also support additional sensor integration. For owners specifically using a factory-style Dodge Ram 6.7L diesel intake manifold pressure sensor, custom port work may still be required depending on the exact configuration. Under the right setup, drivers may see a reduction in EGTs by up to 200°F and fuel economy gains in the 0.5–1 MPG range, while also supporting long-term engine durability.
2. 6.7 Diesel Intake Horn (2007–2024 Dodge Ram)
Designed for improved flow efficiency and easier installation, this intake horn increases airflow by an impressive 88% over stock. Its near-symmetric 180° design helps minimize turbulence, while the 45-degree angled sensor port simplifies tuning, access, and installation.
Available in black, silver, and red finishes, it also accommodates heating elements for cold-weather operation or sealed ports for warmer climates. It fits Dodge Ram 2500/3500 models from 2007 to 2024, excluding cab and chassis variants. For many owners, this is the most convenient all-around Dodge Ram 6.7L diesel intake manifold upgrade thanks to its strong balance of airflow, compatibility, and built-in sensor support.
3. Intake Manifold + Grid Heater Delete All-In-One Kit
This all-in-one upgrade targets a well-known issue in Dodge Ram 6.7L diesel engines: grid heater bolt failures and carbon buildup. Designed to help eliminate this risk, it combines an upgraded intake manifold with a grid heater delete plate, making it a strong choice for owners who want a cleaner intake path and better long-term reliability.
This Dodge Ram 6.7L diesel intake manifold upgrade also supports the addition of an external coil heater, helping maintain dependable cold starts while maximizing airflow and engine response. It is especially attractive for diesel truck owners who want to reduce restriction while addressing one of the most discussed factory intake concerns on the 6.7L platform.
Broad Fitment from 2007 to 2024 – Seamless Compatibility with Dodge Ram Models
When upgrading your intake manifold or planning a full Dodge Ram 6.7L diesel intake manifold upgrade, fitment is one of the most important factors. SPELAB has engineered its products for strong compatibility with Dodge Ram 2500 and 3500 trucks equipped with the 6.7L diesel engine, covering model years from 2007 through 2024.
Here’s how our three featured intake manifold products line up by fitment and compatibility:
-
3.5'' Intake Manifold: Fits 2007–2018 Dodge Ram 2500/3500. Designed for high airflow needs.
Note: This product does not include a direct pre-drilled factory-style port for the Dodge Ram 6.7L diesel intake manifold pressure sensor. Depending on the sensor setup, custom drilling or port adaptation may be required.
-
6.7L Diesel Intake Horn: Fits 2007–2024 Dodge Ram 2500/3500 (excludes cab & chassis models).
Includes a built-in 45-degree angled sensor port for easier integration with your factory Dodge Ram 6.7L diesel intake manifold pressure sensor, with no extra drilling required in most applications.

At SPELAB, we understand that plug-and-play compatibility is a top priority for truck owners and performance enthusiasts. That’s why our air intake manifold solutions are designed to meet both OEM-style installation expectations and the needs of custom performance builds. For those who need built-in sensor support, the Intake Horn upgrade is the most convenient solution. For drivers focused on maximum airflow, the 3.5'' manifold is the stronger performance option.
All SPELAB products are pre-tested for fitment and structural integrity, and come with comprehensive installation instructions. Whether you're handling a DIY install or working with a professional shop, you can expect a smoother and more efficient setup process.
Balanced Performance – Airflow, Temperature Control, and Fuel Efficiency
Every 6.7L diesel intake horn from SPELAB is more than just a replacement part—it is a performance-focused improvement to your diesel engine’s breathing system. Using advanced airflow engineering and heat-resistant materials, these Dodge Ram 6.7L diesel intake manifold products are built to deliver a balanced improvement in power, heat control, and efficiency.
1. Enhanced Airflow: Help Your Engine Breathe Better
With larger internal passages and optimized flow geometry, SPELAB intake manifolds can deliver up to 88% more airflow compared to stock, especially with the Intake Horn design. This allows more oxygen to reach the combustion chamber, which can improve throttle response, support stronger engine output, and make power delivery feel smoother and more consistent.
2. Superior Heat Management: Reduce EGT and Protect Your Engine
When towing or operating under heavy load, diesel engines can experience high Exhaust Gas Temperatures (EGTs). SPELAB’s air intake manifold designs may help reduce EGT by approximately 50–200°F, depending on setup and driving conditions. That can help relieve stress on your turbocharger, pistons, and other high-heat components, especially during long hauls or demanding work use.
3. Better Fuel Economy: Efficient Combustion, Real Savings
By improving airflow distribution and helping support more complete combustion, SPELAB intake manifolds may deliver fuel economy gains in the 0.5 to 1 MPG range for Dodge Ram 2500 and 3500 trucks, depending on setup, load, and driving style. For many owners, the improvement is not only about MPG, but also about more stable performance under load.
4. Built to Last: Premium Materials and Structural Integrity
Each engine intake manifold is crafted from mirror-polished stainless steel or cast aluminum, depending on product design, providing strong resistance to heat, pressure, and corrosion. With reinforced wall thickness and precision manufacturing, these manifolds are built to withstand the harsh environment of heavy-duty diesel use while maintaining long-term reliability.
