Cummins engines are known for their robust construction. However, in order to take better advantage of them, their presence in a better condition is necessary. Their main components require upgrading the cummins intake manifold and the Cummins valve cover. If it is about the machinery of heavy duty vehicles, the presence of these parts ensures the better efficiency of the engine. One of the very essential thing that we see in every engine even be it a Cummins engine is an intake manifold. This also makes sure that the air is distributed to cylinders well and evenly. The air that is sucked into the chambers give’s engine correct amount of oxygen and content from fuel too for igniting it. 

 An engine cannot function properly without proper air flow. Its efficiency can be improved by supplying adequate air to the cylinders. A well-designed intake in a cummins engine multiplies power output and throttle response. More air means more power, which an upgraded intake can do well.

Improved Intake Manifold: A High-Performance Enhancement 

Principal Benefits: The New Intake Manifold is the finest option for people who expect nothing less than the best. This manifold, which costs $598, has twice as much airflow capacity as the factory manifold, which greatly reduces carbon buildup and increases horsepower. Off-roaders, heavy-duty tow operators, and performance aficionados that need the most power out of their vehicle will find this product to be perfect.
Suggested Add-On: We advise combining it with the $109.77 EGR Delete Kit for even better outcomes. By doing this, carbon buildup in exhaust fumes is removed, keeping your engine clean and effective for many years to come.

Comparison of Performance: Upgrade vs. Budget

It’s critical to take the MAF (Mass Air Flow) and CFM airflow into account while deciding between the OEM (Stock) Manifold, 3.5″ Budget Intake Manifold, and New Intake Manifold. You can better comprehend how much oxygen and airflow each manifold delivers for combustion by looking at these numbers, which have a direct influence on engine efficiency and power production.

• Airflow (CFM) Comparative Analysis: New Intake Manifold: 897 CFM – Maximum airflow capacity, enabling best engine performance, particularly with an EGR deletion kit installed.
• 3.5″ Budget Intake Manifold: 487 CFM – A notable upgrade above standard, offering a performance gain that is affordable.
• OEM (original) Manifold: 421 CFM – Engine performance is restricted by the original manifold’s restricted airflow, particularly when large loads are applied.
  In order to maximize horsepower and efficiency, the new intake manifold has the highest mass air flow (MAF) comparison (lbs/min) at 72.7 lbs/min.
• 3.5″ Budget Intake Manifold: 43.5 lbs/min – Offers a significant increase in MAF, enhancing daily drivers’ performance.
• OEM (Stock) Manifold: 38.6 lbs/min – Offers the least amount of oxygen, which prevents your engine from operating at its maximum capacity.

Intake Manifolds and Valve Covers Performance

All intakes are not created equal, there are must be some difference in their design. Manifolds on the market are usually made of composite steel or aluminum. Upgraded engines are designed for more airflow. Which guarantees better performance. A better intake can work many times faster which makes driving fun. Better air distribution directly affects engine performance. Valve cover is also an important engine component although it is usually overlooked it sits on top of the cylinder head. Its main function is to clean engine oil. To prevent wastage and prevent engine parts from getting dirty, Inferior engines often operate in extreme conditions, so the valve cover protects other components from dust and dirt.Also, it maintains the internal lubrication in case there is no oil from outside to go inside.

Conclusion

Such products are generally made of strong material. Moreover, these aftermarket products not only protect the engine but also help to improve the look of it. The intake manifold and valve cover can be upgraded to improve the engine’s durability, performance as well as aesthetics. But it is very important to choose best suitable components according your needs. The intake manifold you choose for your 6.7L Cummins engine will determine its performance and how to solve airflow-related problems. It’s crucial to realize that the intake manifold by itself won’t immediately address carbon buildup issues; this is where the EGR deletion kit comes into play.

Important lessons learned: 

1. For Optimal Power and Airflow: To enhance engine efficiency, the New Intake Manifold delivers the maximum CFM and MAF, which results in a noticeable performance gain.
   
2. For Users on a Tight Budget: The New Intake Manifold outperforms the 3.5” Budget Intake Manifold in terms of performance, but it offers a discernible improvement over stock at a more reasonable price.
   You may significantly increase engine cleanliness and airflow by coupling an EGR delete kit with a new intake manifold, assuring top performance and long-term dependability.

FAQ 

Q1: What leads to the accumulation of carbon in my 6.7L Cummins engine?
A1: Incomplete combustion of recirculated exhaust gases and blockages in the EGR system are the main causes of carbon accumulation.

Q2: Is there a way to get rid of carbon buildup in my engine forever?
A2: The best course of action is to install an EGR delete kit, which stops exhaust gasses from being recirculated and hence removes carbon buildup at its source.

3. Does improving the intake manifold reduce the accumulation of carbon?
A3: Upgrading the intake manifold does not immediately clean or prevent carbon buildup; rather, it improves airflow (CFM) for greater engine performance. It works best when paired with an EGR delete kit.

Q4: How do CFM and MAF differ from one another?

A4: Both CFM (Cubic Feet per Minute) and MAF (Mass Air Flow), which measure the volume and weight of air entering the engine respectively, are essential for efficient combustion.

Q5: How is engine performance enhanced by the new intake manifold?
A5: The New Intake Manifold maximizes combustion efficiency and increases horsepower by delivering much greater airflow (897 CFM) and mass air flow (72.7 lbs/min).

Q6: What is the difference between the OEM manifold and the 3.5″ Budget Intake Manifold?
A6: Compared to the OEM manifold, the 3.5″ Budget Intake Manifold provides superior airflow (487 CFM) and mass air flow (43.5 lbs/min), giving a substantial performance improvement at a reduced cost.
