  1. Hey there.  With regards to the RotoFab CAI for the ‘20 GMC Sierra 1500 5.3L as opposed to the factory GM CAI upgrade.....the GM installed CAI gets a dealer tune/recalibration.  What is this recalibration that is being done with the Gm Cai that I’m not getting if I go the RotoFab route?

      While we can't speak for any competing products, I can tell you a few things about our development process:

      During development one of our main goals is to produce a system that will perform great on the factory calibration. This is no easy task, especially on newer GM vehicles. We implement unique development and prototyping methods which allow us to test over 100 different configurations on the road and track. By closely monitoring and logging pertinent data over the course of many months, we arrive at what we consider to be the “perfect” cold air intake for the vehicle. Then we tool up for production and prepare for release. At Roto-fab, the constant chase for perfection is the real motivation for everything we do.
