Accel, Edelbrock, and TPIS TPI Comparison

Q: Are the Accel, Edelbrock and TPIS TPI intake base the same?

A: The Edelbrock and TPIS TPI intake base are both made by Edelbrock. TPIS does go one step further and port matches all the entries and exits on the manifold and the others do not.

Accell makes their own TPI intake base.

All three TPI intake bases are pretty much the same, and you would be hard pressed to tell the difference in performance between the three.
