Improved Airflow and Performance for GM 6.6L Gas Models

If you're looking to let your 6.6L gas-powered HD breathe a little easier, the S&B 75-5158D Cold Air Intake is the kind of upgrade that delivers noticeable gains without overcomplicating your setup. This system is built to replace the restrictive factory airbox and drop in a more efficient, better-flowing design—all while protecting your engine from heat and debris. It’s a smart way to unlock more performance, improve throttle response, and support future upgrades. What's more, the fully enclosed airbox does a great job of isolating the filter from engine heat, while still pulling in cool outside air from dual inlet points. There’s even a removable box plug that lets you control how much air enters the system, which comes in handy depending on the climate or your specific tuning needs.

Snap-In Lid Upgrade with Simple Install

S&B's new snap-in lid design is a big bonus—no screws or clips to fumble with. Just pop it open for a quick filter check or cleaning and you’re back on the road. The dry extendable filter media is a low-maintenance option that still delivers excellent filtration and airflow, so it’s ideal for anyone who wants solid performance without the mess of oiling. Everything about this intake feels well thought out. From the high-temp silicone couplers to the powder-coated airbox and molded intake tube, the quality is exactly what you'd expect from S&B. Install is straightforward with basic tools, and thanks to their careful mass airflow sensor calibration, you won’t run into check engine lights or tuning headaches. This cold air intake works great as a standalone upgrade, but it really shines when paired with a custom exhaust, throttle body spacer, or tuner.
