Holley EFI Terminator X High Impedance 220-LB/HR Fuel Injectors

This kit replaces all components and provide a new, larger, free flowing system that flows roughly 34% more than stock.

The APR Throttle Body Inlet System is a comprehensive upgrade to the factory charge pipe system from the intercooler outlet to the throttle body. This kit replaces all components and provide a new, larger, free flowing system that flows roughly 34% more than stock.

This was achieved by increasing the cross sectional area of the system and by reducing the tight radius bend directly in front of the throttle body. This system does away with two potential boost leak points thanks to its single cast design. Holley upgraded the factory rubber intercooler outlet hose to a multi-ply wire-reinforced silicone design with strong t-bolt clamps that resist boost leaks better than their stock counterparts.
