Out with the old, in with the new! Just finished installing my new S&B Cold Air Intake on my Duramax, and I couldn’t be happier. The fit and finish are perfect, installation was straightforward, and the quality is top-notch compared to the factory setup.
I replaced both the hot side and cold side tubes, and the difference is night and day. Throttle response feels sharper, turbo spool is quicker, and the engine just breathes better overall. Plus, I really like the clear lid it looks clean under the hood and makes filter checks easy.
Huge improvement over stock, both in performance and appearance. Highly recommend to anyone looking to upgrade their Duramax
