FAQ:

Q: Where is the fuel injector in a Vortec?

A: The Vortec Central Sequential Fuel Injection system utilizes a unique fuel injector for each cylinder. The injector coil is located in the central ‘spider’ with a tube sending the injected fuel to a poppet nozzle in the port of each cylinder.

Q: What is the Spider unit on a Vortec?

A: The plastic pintle tube acts as an insulator to the injector tip which decreases the amount of carbon that’s able to develop on the end of the injector. GM has engineered a new Spider unit and it was used on 2002-2007 Vortec motors. This same unit can be installed on your 1996-2001 Vortec with no mods needed.

Q: Can a Vortec Spider be converted to MPFI?

A: Below is an example of the original CSFI Vortec Spider. The Auto Shop’s Vortec MPFI conversion eliminates the poppet nozzles, instead placing the injectors at the end of the tubes as shown below. This system fits under your stock upper intake with no visual changes when fully assembled.

Q: When did the GM Spider come out for Vortec?

A: GM has engineered a new Spider unit and it was used on 2002-2007 Vortec motors. This same unit can be installed on your 1996-2001 Vortec with no mods needed.
