This item really sucks

I installed this on my 2011 GMC Sierra 2500 HD. It really sucks. The 6-liter was noticeably louder and had better throttle response. However, do not leave the hood open while the engine is running and small children or small animals are nearby. This thing will suck her out of the ground and suddenly your wife starts yelling at you and you're the bad guy. But the product works just as well as the more expensive ones and comes with good packaging.

Pros
  • DESIGNED FOR INCREASED POWER AND TORQUE: Bench tested: 50% more airflow than factory air cleaner and intake manifold.
Cons
  • Some errors
