Stinger® System

B5.9L and C8.3L (12-valve) PUSHER: Cummins Bs and Cs possess diesel durability, but the factory turbo set-up limits the true power potential of these engines. Banks Stinger increases engine airflow and brings the turbo to a higher peak boost, faster. Look for stronger acceleration, faster hill-climbing and gains to +75 hp, +171 lb-ft torque, while improving mileage.

C8.3 Stinger: Banks Stinger makes me feel good!

2007-10-15

"The minute I pulled away from Banks, I knew I had something under me I didn't have before."

"The minute I pulled away from Banks, I knew I had something under me I didn't have before. Banks Stinger makes me feel good! It's like it jumps away from stop signs. Up hills my [Cummins C8.3] motorhome used to take in 4th gear, now it goes in 5th or 6th—and that's towing a Honda Civic. On grade to Las Vegas, we were zipping along without even a grunt." —Harold Mallet; Las Vegas, NV
