Vortech Tuner Kit w/ V-3 Si-Trim - Polished - With Charge Cooler (1996-1998 4V 4.6 Mustang Cobra) 4FK218-118L
Polished V-3 Si-Trim Charge-Cooled Tuner Supercharger Kit for 1996-1998 Mustang Cobra 4.6L 4V
The Vortech Superchargers Tuner Kit (PN 4FK218-118L) is a charge-cooled tuner supercharger system designed specifically for 1996-1998 Ford Mustang Cobra models equipped with the 4.6L 4-valve DOHC V8. This configuration combines a polished V-3 Si-Trim internally lubricated centrifugal supercharger with Vortech's air-to-water charge cooler system, providing the airflow efficiency and intake-air temperature control required for serious high-performance Cobra builds.
This exact part number DOES include a charge cooler. It is still classified as a tuner kit, meaning fuel system components and ECM calibration are intentionally excluded so experienced tuners can tailor injectors, pumps, and tuning to their specific horsepower goals.
What This Part Number Is (and Is Not)
- This kit IS: Tuner kit, V-3 Si-Trim, polished finish, WITH air-to-water charge cooler (PN 4FK218-118L)
- This kit is NOT: A complete, street-legal supercharger system

V-3 Si-Trim Supercharger Technology
The V-3 Si-Trim features Vortech's self-contained internal lubrication system, eliminating the need for engine oil feed and return lines. The SQ (Super Quiet) gear drive delivers smooth, quiet operation while maintaining excellent airflow efficiency and reliability.
The advanced impeller and compressor housing - developed in Vortech's supercharger test cell - support aggressive boost levels while minimizing heat generation and parasitic loss.
Integrated Air-to-Water Charge Cooler System
This tuner kit includes Vortech's integrated air-to-water, dual-pass charge cooler, which significantly increases intake-air density and supports higher boost operation. Vortech indicates charge-cooled High Output configurations for this Cobra platform can increase horsepower from 305 to 484 and torque from 285 lb./ft. to 423 lb./ft. when paired with appropriate supporting engine, fuel, and tuning modifications.
Important: Charge-cooled systems require a battery relocation kit (PN 8N150-010, sold separately).
