The S&B 75-5150 Cold Air Intake is engineered specifically for the 2021-2024 Ram 1500 TRX with the supercharged 6.2L Gen 3 HEMI, delivering substantially improved airflow while adding horsepower, torque, and more of the supercharger sound TRX owners want to hear. S&B reports gains of approximately 20-25 horsepower and 20-25 lb-ft of torque, with its published testing showing as much as 23.38 horsepower and 20.53 lb-ft of torque gained. The system improves airflow by approximately 30 percent compared with the factory configuration while maintaining filtration efficiency above 99 percent, giving performance-minded TRX owners increased breathing capacity without sacrificing engine protection. A massive air filter, oversized intake tube, enlarged air scoop inlet, and sealed airbox work together to feed the factory supercharger with a less restrictive supply of air while helping isolate the filter from unwanted engine-bay heat. For stock trucks and modified Gen 3 HEMI builds alike, the S&B intake provides a bolt-on upgrade that combines measurable performance with more aggressive supercharger sound and additional airflow capacity for future modifications.

One of the standout features of the S&B TRX intake is its enormous filter. At nearly two feet long, the filter provides extensive surface area to support the airflow demands of the supercharged 6.2L HEMI. S&B offers the system with either an 8-layer Cotton Cleanable filter or a Dry Extendable filter, allowing owners to choose the filtration and maintenance style that best fits their needs.

S&B also designed the intake tube with future performance modifications in mind. The tube features a large 4.125 x 6.75-inch oval inlet at the filter and transitions to a 4-inch opening at the supercharger. According to S&B, this large-volume design provides unrestricted airflow and leaves the intake prepared for future supercharger upgrades. For TRX owners planning pulley changes, custom tuning, fuel system upgrades, or more serious supercharger combinations, that additional airflow capacity gives the intake room to support the build as it progresses.

Fresh-air delivery is improved through an air scoop inlet that is 30 percent larger than stock. S&B includes a branded radiator cover with a larger opening to the airbox while retaining isolation from engine heat. The airbox also uses S&B’s patented snap-in lid seal, eliminating screws while providing a secure barrier against hot engine-bay air and debris. The result is a cleaner installation that also makes filter inspection and maintenance easier.

The 75-5150 is designed specifically for 2021-2024 Ram 1500 TRX models equipped with the 6.2L gas engine and stock supercharger. It also carries CARB exemption D-590-52, and S&B lists the system as street legal in all U.S. states.

For TRX owners looking for a bolt-on modification that delivers measurable airflow and power gains while making that 6.2L supercharger considerably harder to ignore, the S&B 75-5150 Cold Air Intake is a strong addition to both stock and performance-focused Gen 3 HEMI builds.
