New Arrival: Banks 42297 Ram-Air Intake for 2025–2026 Silverado & Sierra
Parley's Diesel Performance is excited to announce the addition of two new Banks Power Ram-Air Intake systems built specifically for the 2025–2026 Chevy Silverado HD and GMC Sierra HD with the 6.6L Duramax L5P: the Banks 42297 (Oiled Red Filter) and the Banks 42297-D (Dry Black Washable Filter).
The 2025 Duramax added a new crankcase ventilation pressure sensor that causes most aftermarket intakes to throw a check engine light, or even trigger the reduced engine power mode. Banks solved this with two patented devices included with every kit: the Air Mass Control Module and the Crankcase Ventilation Control Module. Together, they allow the intake to flow freely without triggering trouble codes, something no competitor has figured out yet.
The result is a 45% increase in mass air flow over stock, which means more power across the entire RPM range, quicker turbo spool, reduced turbo lag, fewer DPF regen cycles, and better fuel economy. The turbo even spins nearly 3,000 RPM slower, meaning longer turbo life over time. The enclosed housing connects to the OEM hood and ram-air scoops, keeping heat out and pulling in fresh, dense air whether you're crawling or cruising.
Both kits come with a 5-year limited manufacturer warranty and your choice of filter style, oiled or dry depending on your preference and environment.
These intakes are available to order now and ship directly from Banks Power. Visit the links below to grab yours or reach out to our team with any questions.
