Types of Cummins Performance Parts
Cold Air Intakes
Cold air intakes are designed to improve the airflow entering the engine. By replacing factory air intake systems with high-performance options, you can increase horsepower and torque. Brands like AFE and S&B offer options tailored for various Cummins models. These intakes often feature larger diameter tubing and high-flow air filters for optimal performance.
Exhaust Systems
Upgrading your exhaust system can dramatically improve engine performance. High-flow exhaust systems reduce back pressure and enhance the engine’s ability to expel exhaust gases. This not only adds power but can also contribute to a more aggressive exhaust note. Popular brands such as MBRP and Flo-Pro provide a range of options for Cummins trucks.
Tuning Modules
Tuning modules allow you to optimize your engine’s performance by adjusting fuel maps, timing, and other parameters. Products from EFI Live and Edge Products can significantly increase horsepower and torque while improving fuel efficiency. These modules are easy to install and can often be adjusted according to specific driving conditions.
Turbochargers
Turbochargers are critical for increasing engine power and efficiency. By compressing more air into the engine, they enable more fuel to be burned, resulting in greater power output. Brands like BorgWarner and ATS offer turbocharger upgrades that can lead to substantial performance gains.
Fuel Injectors
Upgrading fuel injectors can enhance fuel delivery and combustion efficiency. High-performance injectors from brands like DDP and Industrial Injection can improve throttle response and overall power production. Replacing stock injectors is essential for any significant power upgrades, especially in modified engines.
Intercoolers
Intercoolers play a vital role in reducing intake air temperatures, which can lead to improved engine performance. Cooler air is denser, allowing for more oxygen to enter the engine and thus improving combustion. Brands like Mishimoto and MaxSpool offer intercoolers designed for specific Cummins applications.
Performance Chips
Performance chips are an excellent way to increase horsepower and torque without major mechanical changes. By reprogramming the engine’s computer, chips from Superchips and Bully Dog can provide power gains and improved fuel economy. These chips are often adjustable, allowing for fine-tuning based on modifications.
Suspension Kits
For those who take their Cummins off-road or require improved towing capabilities, upgrading the suspension can enhance handling and ride quality. Kits from BDS and Fox Racing can improve your vehicle’s stability and control under various driving conditions.
Transmission Upgrades
High-performance transmission upgrades can help manage the increased power levels from engine modifications. Brands like Suncoast and BD Diesel offer transmission kits designed to handle additional torque and improve shifting performance, which is vital for those pushing their Cummins to the limit.
