In the world of diesel trucks, every horsepower counts. Whether you’re towing heavy loads across the highway, conquering off-road trails, or simply craving that raw power under the hood, upgrading your ride with the right parts makes all the difference. Today, I’m diving deep into Spelab Auto Parts—a powerhouse in the aftermarket diesel scene that’s been turning heads since 2019.
If you’re searching for reliable, high-performance replacements—from cold air intakes and EGR delete kits to differential covers and full delete systems—SPELAB delivers quality at unbeatable prices. This in-depth guide will cover everything: product breakdowns, real-world benefits, installation insights, customer stories, and why this California-based manufacturer stands out in a crowded market. Let’s get into it.
The Diesel Performance Revolution: Why Upgrades Matter
Modern diesel engines, like the Ford 6.7L Powerstroke, GM 6.6L Duramax, and Cummins 6.7L, are engineering marvels. But factory emissions systems (EGR, DPF, DEF) often rob power, reduce efficiency, and create maintenance headaches. Truck owners frequently report better throttle response, cooler running temperatures, and improved fuel economy after strategic upgrades.
SPELAB specializes in exactly these solutions. Founded in 2019 as a direct manufacturer, they focus on intake, exhaust, engine, cooling, and drivetrain components. Their catalog is packed with parts engineered for durability under boost.
Key Benefits You’ll Notice Immediately:
- Power Gains: Remove restrictions for freer breathing and exhaust flow.
- Reliability: Premium materials like stainless steel, billet aluminum, and robust gaskets.
- Value: Competitive pricing with frequent sales (e.g., 20% off codes like CL20).
- Fitment: Designed as direct replacements for popular trucks—F-250/F-350, Ram 2500/3500, Silverado/Sierra HD.
Spotlight on Best-Selling SPELAB Products
1. Full Delete Kits: Transform Your Diesel
SPELAB’s All-in-One DPF/DEF/EGR/CCV Delete Kits are crowd favorites. For 2011-2019 6.7L Powerstroke, expect comprehensive solutions starting around $1,289.
These kits typically include:
- EGR delete plates/coolers
- DPF/DEF delete pipes
- CCV reroute or recirculating options
- Necessary hardware and gaskets
Real-World Impact: Users report 50-100+ HP gains (with proper tuning), lower EGTs, and simplified maintenance. One Trustpilot reviewer praised the fit and quality on a 6.7L install.
For Cummins fans, check the 2013-2018 6.7L All-in-One Kit or L5P Duramax options. Always verify local emissions laws—these are primarily for off-road/racing use.
2. Cold Air Intakes (CAI): Breathe Easier
Restricted factory airboxes limit your engine. SPELAB’s CAIs for 6.7L Powerstroke (2017-2019), 5.9L Cummins, and LB7/LMM Duramax deliver cooler, denser air. Prices start under $200.
Why It Works:
- High-flow filters with heat shields
- Mandrel-bent tubing
- Noticeable throttle sharpness and potential MPG improvements
3. Differential Covers: Protect Your Drivetrain
Heavy towing? SPELAB’s differential covers for GM 10.5″ 14-bolt, Jeep Dana 30/35, and more feature fluid capacity increases, magnetic drain plugs, and finned designs for better cooling. Often on sale from $188.
These billet or cast pieces add strength and peace of mind on long hauls.
4. CCV Reroute & Catch Can Systems
Oil vapor in the intake is a common diesel issue. SPELAB’s Gen-2 CCV Reroute Kits for 2011+ 6.7L Powerstroke offer rear-exit, filtered, odor-free solutions around $249.
Keeps your intake manifold clean and boosts longevity.
5. Supporting Upgrades: Coolers, Leveling Kits & More
- Transmission Cooler Kits for Ford 6.7L
- 2.5″ Front Leveling Kits with track bar brackets
- EGR Delete plates, up-pipes, exhaust cutouts, and intercooler pipes
The catalog is massive—hundreds of SKUs tailored to specific years and models.
Installation Guides & Pro Tips
Most SPELAB parts are DIY-friendly with basic tools, but deletes and intakes benefit from mechanical experience.
General Steps for a Typical EGR Delete (Example):
- Disconnect batteries and drain coolant.
- Remove factory EGR cooler/valve assembly.
- Install SPELAB block-off plates with new gaskets.
- Re-route hoses and sensors as needed.
- Refill fluids and clear codes (tuner recommended).
SPELAB provides detailed instructions, and community YouTube videos abound. Reviewers note solid fitment with minor adjustments on clamps sometimes required.
Pro Tip: Pair deletes with a quality tuner. Many owners run “stock” towing tunes for reliability while enjoying off-road power.
