Three Signature Intake Manifolds for Every Driving Style
SPELAB offers three distinct intake horn solutions tailored for the 6.7L Cummins engine. From high-flow performance upgrades to structurally optimized intake horns, and even all-in-one kits that resolve cold start and carbon buildup issues, each product targets a specific set of performance goals. Whether you're towing heavy loads or just looking for smoother throttle response in daily driving, there's a perfect fit for every Cummins owner.
1. 3.5'' Intake Manifold for 6.7L Cummins (2007–2018)
This 6.7 Cummins intake horn is built for serious airflow. With a 3.5-inch unobstructed inlet feeding into two 3-inch mandrel-bent tubes, it drastically improves air volume to support higher horsepower and torque. It’s ideal for off-road builds, heavy-duty towing, and anyone seeking consistent power under pressure.
Equipped with two NPT sensor ports, it also supports precise integration of a Cummins intake manifold pressure sensor. Drivers can expect a reduction in EGTs by up to 200°F and a 0.5–1 MPG improvement in fuel economy—enhancing both performance and engine longevity.
2. 6.7 Cummins 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 minimizes turbulence, while the 45-degree angled sensor port simplifies tuning and access.
Available in black, silver, and red finishes, it also accommodates heating elements for cold-weather operation or sealed ports for warmer climates. It’s compatible with Dodge Ram 2500/3500 models from 2007 to 2024, excluding cab and chassis variants.
3. Intake Manifold + Grid Heater Delete All-In-One Kit
This all-in-one upgrade targets a well-known issue in 6.7L Cummins engines: grid heater bolt failures and carbon buildup. Designed to eliminate this risk, it combines an upgraded intake manifold with a grid heater delete plate—making it ideal for cold-climate users or those seeking long-term reliability.
This 6.7 Cummins intake manifold upgrade also supports the addition of an external coil heater, ensuring dependable cold starts while maximizing airflow and engine response.
Broad Fitment from 2007 to 2024 – Seamless Compatibility with Dodge Ram Models
When upgrading your intake manifold or planning a full 6.7 Cummins intake manifold upgrade, fitment is one of the most critical factors. SPELAB has engineered its products to ensure maximum compatibility with Dodge Ram 2500 and 3500 trucks equipped with the 6.7L Cummins diesel engine, covering model years from 2007 all the way to 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 pre-drilled port for the Cummins intake manifold pressure sensor. Users must drill a custom port if sensor installation is required.
-
6.7 Cummins Intake Horn: Fits 2007–2024 Dodge Ram 2500/3500 (excludes cab & chassis models).
Includes a built-in 45-degree angled sensor port for easy integration with your factory Cummins intake manifold pressure sensor, no extra drilling required.
-
Intake Manifold + Grid Heater Delete All-In-One Kit: Compatible with all 2007–2024 Dodge Ram 6.7L Cummins models. Supports both new and old intake designs with full fitment flexibility.
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 carefully designed to meet both OEM and custom performance expectations. For those who need built-in sensor support, the Intake Horn upgrade offers the most convenient solution—eliminating the need for custom modifications.
All SPELAB products are pre-tested for fitment and structural integrity, and come with comprehensive installation instructions. Whether you're doing a DIY install or relying on a professional, you can expect smooth and efficient setup.
Balanced Performance – Airflow, Temperature Control, and Fuel Efficiency
Every 6.7 Cummins intake horn from SPELAB is more than just a structural replacement—it’s a complete upgrade to your diesel engine’s breathing system. Using advanced airflow engineering and high-temperature resistant materials, these Cummins intake manifold products deliver a balanced improvement in power, heat management, and efficiency.
1. Enhanced Airflow: Help Your Engine Breathe Better
With larger internal passages and optimized flow geometry, SPELAB intake manifolds deliver up to 88% more airflow compared to stock (especially true with the Intake Horn model). This allows significantly more oxygen into the combustion chamber, improving throttle response, engine output, and overall driving smoothness.
2. Superior Heat Management: Reduce EGT and Protect Your Engine
When towing or under heavy load, diesel engines can suffer from dangerously high Exhaust Gas Temperatures (EGTs). SPELAB’s air intake manifold designs reduce EGT by 50–200°F, relieving stress on your turbo, pistons, and other high-heat components—perfect for long hauls and demanding work environments.
3. Better Fuel Economy: Efficient Combustion, Real Savings
By optimizing airflow distribution, SPELAB intake manifolds promote more complete combustion. The result? Real-world fuel economy gains of 0.5 to 1 MPG for Dodge Ram 2500 and 3500 trucks in both highway and load-intensive conditions—saving drivers money over time.
4. Built to Last: Premium Materials and Structural Integrity
Each intake manifold is crafted from mirror-polished stainless steel or cast aluminum, offering outstanding heat resistance and corrosion protection. With reinforced wall thickness and precision welding, these manifolds are built to withstand the high-pressure, high-heat environments of heavy-duty diesel use—ensuring long-term reliability.

FAQ
Q1: Will SPELAB intake manifolds fit my 6.7L Cummins engine directly?
A:
Yes. SPELAB’s intake manifold products are designed to fit 2007–2024 Dodge Ram 2500 and 3500 models equipped with the 6.7L Cummins diesel engine. Except for the Intake Horn, which does not fit Cab & Chassis models, all products are engineered for high compatibility and straightforward installation.
Q2: Can I install a pressure sensor on the 3.5'' Intake Manifold?
A:
The 3.5'' engine intake manifold is built for high-flow performance and does not include a pre-drilled port for the Cummins intake manifold pressure sensor. If sensor installation is needed, a custom port must be drilled, preferably by a professional.
Q3: What performance gains can I expect from upgrading the intake manifold?
A:
Upgrading to a SPELAB air intake manifold can deliver noticeable improvements in airflow, throttle response, fuel efficiency, and reduced EGT (Exhaust Gas Temperatures). Many users report increased pulling power and more consistent performance under load.
Q4: Is a Grid Heater Delete safe in cold climates?
A:
Deleting the grid heater removes the OEM cold-start heating system. If you drive in very cold environments, we recommend adding a coil heater to maintain reliable cold starts after the delete.
Q5: Are SPELAB intake manifolds compatible with EGR Delete kits?
A:
Yes. SPELAB intake products—such as the intake horn—are designed to work seamlessly with our EGR Delete Kits. The interfaces align perfectly, offering smooth performance without triggering errors or fitment issues.
Q6: Do I need special tools or mechanical experience to install these products?
A:
Some products, like the Intake Horn, are DIY-friendly and include clear installation guides. However, tasks like sensor port drilling or Grid Heater removal may require a professional technician to ensure proper sealing and safe operation.
Q7: Will upgrading my intake manifold void my vehicle warranty?
A:
In some cases, installing non-OEM parts may affect specific portions of your factory warranty. We recommend checking with your dealer and keeping your stock parts for future service needs.
