Holley Sniper EFI SNP550-552 Autolite 1100 sku-775947405

Holley Sniper EFI SNP550-552 (sku-775947405, UPC 090127100622) is a Multicolor item in Performance Fuel, Carburetors and Intakes. This bolt-on throttle-body EFI system has a flange for intake manifolds originally fitted with an Autolite 1100 carburetor. Applications include 1963 to 1967 Ford Inline 6 engines from 144ci to 300ci, found in Mustangs, Falcons, Fairlanes and Ford trucks.

The throttle-body-mounted ECU needs no separate box and supports up to 175 HP with one 100lb/hr injector. Installation requires 4 wiring connections: battery positive, battery negative, switched ignition and RPM. An internal fuel-pressure regulator is preset to 58.5 PSI, and the system includes ignition timing control.

A full-color touchscreen handles setup, tuning and gauge displays; a calibration wizard creates a base map and begins self-tuning without a laptop. The included Bosch LSU 4.9 wideband oxygen sensor supports fuel-map learning. It also has OEM-style TPS/IAC and a fuel-pressure regulator.

A clamp-on oxygen-sensor kit fits 2" exhaust and includes stainless-steel T-bolt clamps and a weldable stainless-steel sensor flange. The source title describes the finish as Gold.
