High-Performance Intake Manifolds & Intake Horns
Unlock the true potential of your engine with SPELAB's precision-engineered intake manifolds. Whether you are looking to eliminate the restrictive factory design on a 6.7L Cummins, replace the prone-to-fail plastic manifold on a 6.7L Powerstroke, upgrade your Duramax LML/L5P, or breathe new life into a classic Ford FE V8, our collection delivers maximum airflow and reliability.
We utilize high-grade Cast Aluminum, Billet Aluminum, and T-304 Stainless Steel to solve common OEM issues: cracking, warping, and heat soak. By optimizing plenum volume and runner geometry, SPELAB intake systems lower Exhaust Gas Temperatures (EGTs), improve throttle response, and increase horsepower.
1. Engine-Specific Upgrades: Find Your Solution
1.1 6.7L Cummins Intake Horns (2007.5-2024)
The stock intake horn on the Dodge Ram 6.7L Cummins is notoriously restrictive. Our 6.7 Cummins High-Flow Intake Horns feature a larger 3.5-inch inlet and smooth mandrel bends to increase airflow (CFM). Available in Fabricated Stainless Steel for ultimate strength or Cast Aluminum for heat dissipation. Many owners pair this with a Grid Heater Delete to eliminate the risk of engine failure.
1.2 6.7L Powerstroke Intake Manifolds (2011-2019)
For Ford Super Duty owners, the factory plastic intake manifold is a ticking time bomb that can crack under boost. SPELAB offers a durable Cast Aluminum 6.7L Powerstroke Intake Manifold replacement. This upgrade prevents catastrophic plastic failure and removes internal restrictions, making it essential for tuned or towing trucks.
1.3 Duramax LML & L5P Intake Solutions
Maximize flow into your Chevy or GMC engine with our Performance Intake Manifolds and Bridges. Designed for the 6.6L Duramax, these upgrades replace the restrictive factory Y-bridge and piping, smoothing out the air path for faster turbo spool-up.
1.4 Ford FE V8 Intake Manifolds (390/427/428)
Restore the glory of your classic muscle car. Our Aluminum Ford FE Intake Manifolds are available in Dual-Plane designs, perfect for street performance. They offer significant weight reduction over stock cast iron while improving the power band from idle to 5500 RPM.
2. Material Science: Aluminum vs. Stainless Steel vs. Plastic
Why do we use specific materials? It comes down to application:
- Cast & Billet Aluminum: Excellent heat dissipation properties. Aluminum cools down faster than iron or steel, helping to keep the intake charge dense. It is the standard for our manifold bases and plenums.
- T-304 Stainless Steel: Used in our fabricated intake horns and piping. Stainless steel offers superior tensile strength to handle extreme boost pressures (100+ PSI) without deformation and is impervious to rust and corrosion.
- Stock Plastic (The Enemy): Prone to heat fatigue, brittleness, and cracking. We replace this weak material to ensure your truck stays on the road.
3. Installation & Supporting Mods
To get the most out of your new intake manifold, consider the entire air system.
- Intercooler Pipes: Pair your manifold with a High-Flow Intercooler Pipe Kit to remove the next restriction in the line.
- EGR Delete: For off-road competition diesels, installing an intake manifold is the perfect time to perform an EGR delete to prevent soot buildup from clogging your new part.
4. Why Choose SPELAB? Engineering & Validation
At SPELAB, we don't just manufacture parts; we engineer solutions. Our development process bridges the gap between OEM limitations and aftermarket performance.
4.1 Data-Driven Design (CFD Analysis)
Every intake manifold begins with Computational Fluid Dynamics (CFD) software. We scan the factory bottlenecks—such as the flattened bends on the 6.7 Cummins horn or the baffled runners on the Powerstroke—and redesign the internal geometry. The result is a Laminar Flow path that reduces turbulence and increases air volume by up to 40% over stock.
4.2 Dyno-Proven Horsepower
We validate our engineering on the dyno. While a manifold alone adds efficiency, our testing shows real-world gains when paired with proper tuning:
- Power Gains: Expect increases of 10-25 HP and significant torque improvements in the low-to-mid RPM range.
- Lower EGTs: By supplying dense, oxygen-rich air, our manifolds help cool the combustion cycle, dropping EGTs by 50-150°F during heavy towing.
4.3 "Bulletproof" Reliability
We target known failure points. From the "Killer Grid Heater Bolt" on the Dodge Ram to the bursting plastic pipes on the Ford Super Duty, SPELAB intake systems are built to permanently eliminate the weak links that leave drivers stranded.
4.4 Unmatched Support & Logistics
We believe the buying experience should be as high-performance as the parts. Here is how we support your build:
- Comprehensive Installation Guides: Every product comes with detailed, step-by-step instructions. Whether you are a seasoned mechanic or a DIY enthusiast, our guides ensure a smooth, error-free installation.
- Fast Shipping (4 US Warehouses): We operate four strategic warehouses across the East, West, and Central United States (Florida, Kentucky, California, and New Jersey). This network allows us to dispatch orders rapidly, minimizing downtime and getting you back on the road faster.
- Professional Technical Support: Not sure about fitment? Our team of automotive experts is ready to assist. We provide professional advice to help you choose the exact part for your specific engine generation and build goals.
5. Frequently Asked Questions (FAQ)
Q1: Does the 6.7 Cummins intake horn upgrade require a tune?
A1: If you are simply upgrading the intake horn for better airflow, a tune is typically not required. However, if you are performing a Grid Heater Delete or EGR delete alongside the installation, tuning is required to prevent check engine codes.
Q2: Why replace the 6.7 Powerstroke plastic manifold?
A2: The stock plastic manifold is prone to cracking and bursting, especially on trucks with higher mileage or tunes. Upgrading to a Cast Aluminum Manifold permanently solves this reliability issue and handles higher boost pressures safely.
Q3: What is the difference between Single-Plane and Dual-Plane for Ford FE?
A3: A Dual-Plane manifold (like the SPELAB Typhoon series) is best for street use, offering better low-end torque and throttle response. A Single-Plane manifold is better for high-RPM racing applications.
Q4: Will this improve my fuel economy?
A4: By reducing the engine's pumping loss (it doesn't have to work as hard to suck in air), many drivers report a slight improvement in MPG during steady highway cruising, in addition to the power gains.

Excellent quality.
I have a 2017 Ram 2500 2wd and looking to make it last as long as possible. With extra fluid capacity and cooling fins, I felt that this is better than stock. The hardware that came with it looks great and appreciated because I was going to replace the old anyways. Even the gasket is heavy-duty and looks like it's reusable if needed. Not a thin felt like material but a thicker quality rubber. Shipping was like 4 days. I am pleased with my purchase and would highly recommend it.
Highly recommend clean, good quality, fast shipping. 100% haves my business is had my power coated
Everything went in and on very smoothly everything fit and as should only thing I will say is does not come with bolts for up pipe and the gaskets are decent but would upgrade to some mahle gaskets and get a set of ppe up pipe bolts other than that very solid affordable set of parts the coating on the up pipe will burn off due to heat but it does not affect performance of part or affect truck at all definitely recommend if your looking for performance parts while trying to save some money it definitely gave my Lly duramax the tone and power I was looking for!
I received a box with no grid heater delete got a hold of customer service and receive one in three days. Fantastic service.
Install was easy works great at a fraction of the price. Heat element started truck at 8 degrees the other day just like the original grid heater did.
Worth the money and 1/4 of the price 100% recommend them i run the pipe 1 my dad runs there newer style both are worth the money. And just put 1 on my father's in-law truck.
Installed on ford e350 super duty dana 70fit was perfect
Having trouble keeping clap rings on the hose and pipe they keep blowing off when boost pressure coming up.
Perfect fitment and function.
I have a 2005 ram with the 5.7 I had a 2018 challenger with duel coil packs so I got this valve cover to fit and used the mmx adapters and boom! Looks amazing. Only thing is the screws and lock washers are not good...torque specs will break the lock washers and I think one coil thread hole got stripped but other than that I got it too work. Thanks!
Install was easy as long as you take the fuel line off the manifold and reinstall it after bolting down the intake. It also helps having an intake heater since removing the grid heater. No more check engine lights after a cold start. The quality of Spelabs products are great. And the price point is even better.
combined it with the intake horn, new intercooler and pipe kit. added the valve cover. Seems to function well. instructions were adequate- could be better. I assume a few of the complaints on the reviews may have been instruction related. We will see how it compares- ran stock for 230k- will try this now.
Bought this kit as part of a larger overall DCR Pump conversion. Kit came quick, complete and works as advertised.
Very pleased with spelab. My horn is awesome and arrived in great shape. The heating element however I was not so lucky with. It arrived damaged. I reached out to spelabs support and they promptly sent me a new one free of charge. Installing that tonight. 5 stars
