Recently, on automotive enthusiast forums, there have been discussions mainly expressing concerns about the impact of modifications on other systems when enhancing certain performance aspects of a car.

Some enthusiasts, after modifying the exhaust system, find themselves needing additional accessories to address other related issues.

Consequently, they end up having to purchase 5-10 packages from various stores, making the process quite cumbersome.

SPELAB, based on our current product lineup and analyzing user purchasing patterns, has strategically combined products that enthusiasts frequently buy. This not only saves time for our customers but also provides them with more favorable deals.

Currently, SPELAB offers 17 combination products, including those for Duramax, Powerstroke, Cummins, Ecodiesel, and other major engine types. Here, we will focus on our key combinations.


Compliant Performance Upgrades: Enhancing Valve Cover, Oil Catch Can, and CCV

SPELAB combined Valve Covers, Oil Catch Cans, and Crankcase Ventilation Valves (CCV) based on customer feedback and market research.

This combination effectively controls internal engine gases, reduces oil leaks, prevents oil vapor from entering the intake system, and enhances engine efficiency and reliability.

Importantly, each product in this combination has undergone either appearance or performance optimization for significant improvements.


Valve Cover

The valve cover's primary role is to protect the valve mechanism, with its sealing performance being crucial. While most stores offer functional valve covers, SPELAB has made innovations in appearance, convenience, and aesthetics.


We offer customization based on user feedback, allowing vibrant rainbow colors (inspired by Jen Cresswell) and other color coatings.

Additional features include font polishing techniques, custom logos, and more, demonstrating our commitment to consumer feedback.

Performance Optimization

Addressing common complaints about CCV filter clogging, SPELAB replaced the factory CCV filter with a maintenance-free CCV vent.

Efficiently handling waste oil, SPELAB's 6.7 Cummins valve cover has two ports that can connect to an oil catch can + CCV delete kit, providing double the effect compared to other stores.

Oil Catch Can

Oil vapor generated inside the engine may contain impurities, and an oil catch can prevents these impurities from entering the engine's intake system. It helps maintain internal engine cleanliness and improves combustion efficiency. According to consumer feedback, many users use an oil catch can after removing EGR or DPF to better manage oil vapor.


CCV plays a significant role, and using a CCV/PCV ReRoute engine ventilation kit is usually legal. It helps reduce oil contamination, keep the engine clean, and improve oil stability.

This combination kit is priced at only $454.89 USD, whereas purchasing each item separately would cost a total of $494.45 USD. This represents a saving of nearly $40. Additionally, SPELAB's L5P delete kit is highly popular.

On SPELAB's combined product aggregation page, you can find all our existing combination products. We welcome any feedback.

Furthermore, we have good news –AS a DPF delete shop,from January 15th to 18th,we will be introducing some DPF pipes in several combination products.

About SPELAB Combination Product Logistics

In conclusion, we strive to meet the needs of consumers as best as we can.

However, product combinations require coordination between many departments, including operations, logistics, and collaboration across multiple warehouses.

Some combination products are in different warehouses, so customers may receive multiple packages, and the arrival times may vary.

This is not an issue we neglect. SPELAB has its own factory but also collaborates with other reputable suppliers, such as Mini Maxx.

The products in our combination are single items from different accessory brand suppliers.

Therefore, this situation may arise. However, this is not unique; in fact, almost all businesses encounter similar issues in the market.

About SPELAB Combination Product After-Sales Service

You don't have to worry; we have a comprehensive after-sales service. If you have any issues, we offer a 7-day refund policy. You can read our return policy for detailed information.

Our service may not be perfect, but we are constantly improving and growing. We welcome any customer feedback and opinions. You can comment on the blog or provide feedback on our social media.




While we endorse automated services, we believe human customer service can better understand your needs.

Currently, all our customer services are provided by human agents. However, to quickly resolve common consumer issues, SPELAB will soon gather all after-sales issues and compile a blog with frequently asked questions.

We hope to address consumer problems rapidly without waiting. Moreover, we will continuously update questions and solutions. Stay tuned.
