Hello everyone.

I'm trying to understand the benefits of upgrading the airflow system on my diesel truck, especially for towing and daily driving. There are many aftermarket options that claim improvements in throttle response, fuel economy, and overall efficiency, but the results seem mixed.

Can anyone explain 6.7 cummins intake horn makes a noticeable difference in real-world performance, or is it mostly minor?

I'm looking for honest feedback from people who have actually installed it on a 6.7 Cummins, especially regarding towing, daily reliability, and whether supporting modifications are needed to see real gains compared to the stock intake setup.

 

thanks in advance for any help
