The engine valve cover is an essential protective component for diesel engines. It shields crucial parts within the valve chamber—such as valves, springs, and rocker arms—from contaminants and damage. Choosing the right valve cover can make a big difference in your engine's performance, reliability, and longevity.
At SPELAB, we understand the importance of both functionality and aesthetics. We design our Cummins billet valve covers in-house to offer the best balance of fit, finish, and functionality, while keeping your budget in mind. Our valve covers are made from aircraft-grade 6061-T6 aluminum and come equipped with all stainless steel fasteners. Explore our range of valve cover products to find the perfect match for your diesel engine today!

Our innovative products
Reinforced and Reliable: SPELAB valve covers have a reinforced aluminum inner structure that exceeds conventional market standards in terms of durability. Our materials and structure can withstand temperatures up to 600°F and pressures of up to 120 PSI, handling even the most demanding conditions with ease.
Integrated CCV Filter: The valve covers are designed with direct CCV (Crankcase Ventilation) filter ports that fit perfectly. This design effectively redirects up to 95% of oil vapors to reduce oil mist in the intake tract, helping keep the engine cleaner and performing at its best.
One-Stop Installation Kit: Our valve covers come with everything you need right out of the box, so there's no need for extra purchases. The kit includes a CCV filter, hoses, clamps, filter cartridges, and brackets, making DIY installation easy, even for beginners, with clear installation instructions.
Personalization Options: Valve covers feature the SPELAB logo and are available in a variety of colors, letting you customize the look of your engine compartment to match your style.
What product is the best?
1. Material
Cast Aluminum: This is a cheaper and common material. It is more durable, dissipates heat well, and is suitable for daily driving or light modifications. However, for extreme performance, cast aluminum is not as strong.
Billet Aluminum: Since billet aluminum valve covers are made from a single block of aluminum, they are stronger and more durable than cast aluminum. Valve covers made from billet aluminum can withstand higher pressures and temperatures, making them ideal for high performance or modified vehicles.
Carbon Fiber: Carbon fiber valve covers are lightweight and strong, making them ideal for racing or extreme conditions. However, they are expensive and not suitable for daily driving.
2. Manufacturing Processes
CNC Machining: This process is used for billet aluminum valve covers and creates a more accurate and durable valve cover CNC machined valve covers are high quality and ideal for those looking for performance and longevity.
Casting: Cast aluminum valve covers are typically manufactured using the casting process, which is faster and less expensive. Cast valve covers, while strong, are less precise and may not be as durable as CNC machined valve covers, making them ideal for the average driver.
3. Design
Heat dissipation: High-quality valve covers often have special heat dissipation features such as cooling fins. This design keeps engine temperatures stable and is useful for drivers who run their engines at high loads for long periods of time.
Sealing: Good valve covers focus on sealing to prevent oil leaks. This is especially important for modified or high-performance engines.
Custom Looks: Some brands offer color options and logo customization for a personalized touch, like red, silver, black, etc. Billet aluminum covers are particularly easy to customize in terms of appearance.
How to choose the right product
1. Adaptation
Key Consideration: Make sure the product is compatible with your vehicle’s make, model, and engine specifications.
Example: If you own a 2018 Dodge Ram with a 6.7L Cummins engine, you’ll need a valve cover that specifically supports that year and engine type, like fit for the SPELAB 2007-2023 6.7L Cummins valve cover.
2. Price
Key Consideration: Determine your budget and balance it with the quality and features of the product.
Example: If you're looking for an affordable upgrade, cast aluminum valve covers offer good durability at a lower price. For those seeking higher performance and durability, billet aluminum options are available but generally come at a higher cost.
3. Application Market
Key Consideration: Choose a product suited to how you plan to use your vehicle—daily driving, off-road, or racing.
Example: For everyday driving, a standard cast aluminum valve cover will be sufficient. However, for high-performance or off-road use, a billet aluminum cover with CNC machining, like those offered by SPELAB, provides enhanced strength and heat resistance, ideal for demanding conditions.

Nice and simple
The parts were packaged well and customer service was amazing. The instructions were super easy to follow and overall layout of the kit made the install go like a breeze. I only took three hours to install the kit and I’ve hadn’t had a single problem with it. You can hear a difference in the truck and the mileage has gone up. I would recommend this kit.

Perfect Fit
Everything is super high quality, and the absolute best price is could find if i had to complain about anything it would be the exhaust tip I wish the flange for the clamp was .1 longer to get a socket on it.
Product looks good and bolted on with ease. I used the factor fill hole for the first fill and it aligned perfectly with the ball floating in the middle of the sight glass. In the future I can just top fill and use the glass as the gauge. Very happy with it so far!

Great product loved the final looks
The installation went great just to remove the 2024 gmc cover vent you need a t40 bit and to hammer it in to get the security screws out. Love the look and over all installation God Bless.

100% recommend
Easy to install. Data from before and after shows a large gain in airflow. MPG did get slightly better. Only recommendation for SPELAB is that they polish the inside of the horn to keep soot from collecting on non EGR deleted vehicles.
It was easy to install did not come with instructions but i did watch a YouTube video and was done pretty quick.

LML Coolant Tank
Amazing craftsmanship for the price, only beef is it could be powder coated a little higher where the cap goes on an maybe a little bit nicer of a cap but overall 5/5, very impressed.

SPE gets 5+ stars
Kit was complete every thing lined up and I do have more power and better mpg. Customer service helped when FedEx wasn’t delivering once customer service called them. I received the parts in two days.
After adding mine to the car, it looks fantastic. Blends in with the engine bay and doesn't look terrible with the plastic OEM one. It was easy to swap out. The only issue I have is that there is no actual cold marker on the reservoir so I had refilled as the instructions said and it pushed the extra into the overflow tank and it is now overfilled and leaking. I also think having a mount for the batter cable to reattach would be good so the cable isn't laying against the tank would be great. Outside of that it looks great and so far haven't seen any over heating issues.
