If you have a 7.4 vortec, this is a must have. Just comparing the stock MAF with this one, there is going to be better mass volume AND better velocity. The honeycomb is removed, and the Inner diameter is larger. The noticeable difference is right off throttle all the way up to 4500rpm. It is molded plastic though, so we'll see over time if there is any cracking with the heat cycles of the motor compartment. No CEL came on either.
