What would be the advantage in using two EGR spacers together after the throttle body?
Would it lower the maximum torque rpm, or have an affect like the phenolic spacers in increasing torque maybe?
What happens when no EGR spacer is used?
How about modifying two EGR spacers to act like the 'herrod air injection unit'.
Maybe a 65mm TB, into a modified 60mm EGR spacer, into a modified 65mm EGR spacer onto the 70mm intake opening....? (maybe I think too much)
