− | The 1985 Astro van had this intake; passenger cars came standard with TBI fuel injection). Passenger cars (B- and G-body) as well as trucks/vans manufactured after the 1986 model year (including 1988-94 S-series trucks) came with TBI intakes. A central port injection intake manifold (with an upper and lower casting) was introduced in 1992 which has a central fuel injector with six poppet valves (used with the Astro/Safari and S-series SUVs (Blazer, Jimmy, Bravada), later revised in 1996. | + | The 1985 Astro van had this intake; passenger cars came standard with TBI fuel injection).

A central port injection intake manifold (with an upper and lower casting) was introduced in 1992 which has a central fuel injector with six poppet valves (used with the Astro/Safari and S-series SUVs (Blazer, Jimmy, Bravada), later revised in 1996 with sequential fuel injection. Central port injector used with 1996-01 were known to have fuel leakage where GM redesigned the fuel spider which converts the CSFI system to a multipoint injection system. |
The limited production Syclone/Typhoon has an intake manifold which uses a multipoint injection setup (with a throttle body similar to the one used with the tune port injected Corvettes and IROC-Z Camaro/Trans Am) - parts for such a conversion do not exist from the aftermarket. | The limited production Syclone/Typhoon has an intake manifold which uses a multipoint injection setup (with a throttle body similar to the one used with the tune port injected Corvettes and IROC-Z Camaro/Trans Am) - parts for such a conversion do not exist from the aftermarket. |
