Just The Facts

Multi-Port Fuel Injection (MFI) System

GM’s Vortec engines come with a Sequential Port Injection System (SCPI). Standard’s Multi-Port Fuel Injection (MFI) system has several advantages over the original Sequential Central Port Injection (SCPI) system, including port fuel delivery and high reliability, better hot starts and reduced vapor emissions, and faster prime on hot restarts.

The above Multi-Port Fuel Injector is also available for the GM V8.

Manufacturing and Testing

Designed and Built in the USA

Standard® injectors are designed and built at SMP’s vertically integrated TS16949-certified manufacturing plant in Greenville, SC. As a result, we’re able to yield fuel injectors that meet our strict quality control standards. In addition to designing and engineering, we subject our injectors to extensive end-of-line and life cycle testing.

Passing the Test

To make sure every fuel injector meets our strict standards for precision quality, enhanced performance, and extra durability, Standard® perform initial life-cycle validation and 100% end-of-line testing. What’s more, we subject our fuel injectors to more than 35 different tests and inspections. Here are just a few of the elements and components that we test and inspect:
