5.7 manifold TB has been in the same location for 7 years so who knows how many CAI's are out there. Not worth the time and effect to research that.
Below is the only aftermarket CAI i had with the 5.7 manifold. Worked great for 3-4 years. Not show quality but hey - function over form.
AIR RAM CAI w/ Jetscoop
This is what i have now.
