Box3 is the complete set of intercooler piping with all the silicone couplers and clamps with optional wrinkle black powder coating.
Intercooler options are as follows-
No intercooler at all (because you bought a used one or such)
Intercooler delete pipe, this is just a 3" aluminum pipe bead rolled on both ends. (for entry level 4-6psi 500-550whp)
Endurance race intercooler 12" wide core (blocks less of the radiator so best for hotter weather or continual aggressive driving)
Drag race intercooler 20" wide core (best for maximum power or cooler climate areas)
