or Post- throttle body/carburetor?
• Performance: It makes almost no difference. Before or after the throttle plate(s) wont change the effectiveness of the fluid. A given amount of fluid will absorb a given amount of heat, whether it is done more before or after the throttle plate really doesnt matter. • Installation: It is usually easier to inject pre-throttle body in the intake tube. Easy access, no solenoid required (unless rear-mounting a reservoir). On a carburetor, it can actually be easier to use the #40050 carb spacer plate and a #40060 solenoid for a bolt-in installation. These components are included in our RT and MC series systems. • In a blow-through carburetor setup with an air-box enclosure around the entire carburetor, injecting after the carburetor is preferable.
