Bought 2 of these after the 5.3L in my '08 Tahoe dropped 2 cylinders at 147K miles. Stuck them in my Tahoe (after a new engine) and '14 Silverado to make sure I don't have problems in the future. Maybe slight decrease in fuel economy, but doesn't appear to be much. Provides some peace of mind which makes it worth it for me.
