About Spelab
Some truck owners hit a wall with airflow. The 6.7 Cummins runs strong, but the stock intake setup can feel a little bottled up once you start towing heavy or pushing the truck harder than factory conditions. Heat climbs. Response softens. You can feel the motor asking for more air than it’s getting.
Spelab stepped into this space a few years ago and built parts for people who want something better than what rolled off the lot. They build their stuff, ship it themselves, and actually talk to their customers. They stay in the performance lane, so the parts aren’t random accessories pulled from a warehouse. They come from a company that pays attention to how these engines behave in real use.
The draw is pretty simple. Their catalog stays affordable compared to a lot of aftermarket names. The parts come ready to install. They send them out fast from multiple US warehouses. And if someone has an issue, there’s a real support team instead of a maze of automated replies.
One of their most talked-about pieces is the 3.5-inch intake manifold for the 6.7 Cummins. On paper, it frees up airflow, drops temps, and cleans up how the engine breathes under load.
That’s the promise. The question is how it actually runs once it’s bolted on. Plenty of companies say their parts make a difference. Only some deliver. So let’s look at what Spelab put together and see how this thing performs.

Intake Horn/Manifold Grid Heater for 2007-2024 Dodge Ram 2500/3500 6.7 Diesel
Spelab’s intake horn and manifold kit gives the 6.7 Cummins more breathing room than the stock setup, which is known for tight passages and heat buildup under load. The cast aluminum body has a much larger interior path, room for sensors, and ports for a heating element if you run the truck through cold months. It also bolts straight to factory points, so the job stays manageable for anyone who has spent time under the hood of a Ram.
Most of the feedback lines up with what the part claims to do. Ivan Salazar called it a solid upgrade for his Ram, saying, “I made the best decision in choosing Spelab to enhance my 2500 ram truck.” Luke mentioned the install went smoothly once he paired the instructions with a video, and Derrik Kinzebach added that the piece looked good and the install was “just time consuming.” Even Jim, who didn’t love the directions, still said, “the product is great and you can’t beat the price.”
The kit normally sits at $888, but it’s listed at $617 during the sale. For a truck that spends real time towing or running long grades, the airflow jump mixed with the option for cold-weather hardware gives this part a practical edge. The long list of buyers saying it works the way they hoped makes it easier for a 6.7 owner to picture the difference once it’s installed.
3.5″ Intake Manifold with Heating Element for 2007-2024 Dodge Ram 2500/3500 6.7L Cummins
Spelab’s 3.5-inch stainless intake manifold is built for 6.7 Cummins owners who want more airflow without giving up cold-weather starts. The stock grid heater setup on these trucks has a known weak spot, and this design removes that risk by replacing the bolt-style heater with a built-in heating coil. You get a clear intake path and a cold-start system that doesn’t rely on the factory parts that usually cause trouble.
The larger stainless tubing gives the engine a smoother shot of air, which helps the turbo light up quicker and keeps temps under control when the truck is working hard. Two NPT ports sit on the manifold for sensors or a boost gauge, and it uses the factory mounting points so the install stays straightforward. The balanced-airflow plenum and smooth interior walls also cut down on the carbon buildup that the stock intake is known for.
Pricing starts at USD $199.00, which puts it far below most stainless intakes with integrated heating systems. Only the red version ships right away, with black and silver coming back into stock later in the month. This is the hottest new product in December 2025.
If you are someone who wants a high-flow manifold without losing winter reliability, this piece aims to cover both needs in one shot.
Spelab Review: What Do Customers Think?
Spelab gets a steady stream of praise from truck owners who’ve installed their parts and put them to work. Most of the feedback centers on solid fitment, clear gains in airflow, lower temps under load, and kits that arrive with everything needed to get the job done.
A lot of buyers mention that installs go smoothly once they get started, even when they’re not professional mechanics. One review summed up the experience simply: “Fits great! Easy install! All parts come with this as well didn’t need to go out and get anything.” That kind of comment shows up often.
Performance gains come up just as much. Drivers who tow or run heavy loads talk about real drops in EGTs and cleaner throttle response. One owner spelled it out clearly: “After installing the Spelab intake my EGT’s have lowered about 150/200 degrees from stock! I tow 90% of the time with this truck.”
Others mention that paired upgrades, like exhaust and tuning, let the engine run the way it should have from the start. Another review put it in plain words: “The 6.7 is opened up and free to run.”
There’s also a lot of appreciation for the build quality and the overall look of the parts. Many point out smooth finishes, solid construction, and plates that sit flush without leaks. Comments like “Great components solid workmanship” and “Looks clean performs even better” show up across different product lines.
Even when someone talks through a long install story, the conclusion usually lands in the same place, satisfied with the end result and planning to buy again. Several reviewers also talk about the price being fair for what they get, with lines like “Not only that but the price man that’s damn good.”
Is Spelab Legit?
Spelab is a legit parts maker, and you can see it in how they run their business. They manufacture their own components, keep real inventory in multiple US warehouses, ship orders fast, and handle issues through a support team that actually responds. The twelve-month warranty is clear, the parts are stocked for the trucks people actually own, and the company has been around long enough to build a steady presence in the diesel world.
Is Spelab Worth It?
If you run a diesel truck and want upgrades that feel practical instead of overhyped, Spelab lands in a pretty good place. You’re getting parts made by a company that stocks its own inventory in US warehouses, ships quickly, and backs everything with a clear twelve-month warranty. You don’t have to wade through vague policies or chase overseas tracking numbers, and the pricing sits in a range you can plan around without turning every upgrade into a major financial hit.
When you look at their intake options for the 6.7 Cummins, the value becomes even clearer. The cast intake horn and manifold kit opens up the restrictive factory path with a much larger interior layout, up to an 88% percent airflow increase, and a diameter roughly double the stock piece. It has ports for sensors, room for a heating element if you need cold-weather starts, and fits trucks from 2007 through 2024.
The stainless 3.5-inch manifold goes further by building the heating coil directly into the design, which avoids the common grid heater bolt issue while giving you cleaner airflow and easier winter mornings. Both bolt to factory points and come with hardware, so you’re not piecing things together on install day.
When you compare what these parts do to what they cost, the numbers make sense. The intake horn and manifold kit sits at USD 888.00 normally and USD 617.00 during the sale. The stainless 3.5-inch option lands at USD 199.00. For the airflow jump, lower temps under load and the long-term reliability gains, you’re getting strong value without paying premium brand prices. If you want upgrades that actually help your Cummins run smoother, Spelab is a brand you can feel comfortable buying from.
