Description

High-Performance EFI Conversion. The Holley Sniper 2 EFI with Polished Finish is an advanced self-tuning electronic fuel injection system designed to replace traditional carburetors on V8 engines. It improves drivability with features such as easy cold starts, smooth throttle response, and real-time fuel map learning, enhancing power delivery and fuel efficiency for classic vehicles without emissions control.

Construction And Appearance. This EFI system features a polished finish for a shiny and modern look while ensuring durability. The throttle bodies are serialized for quality assurance, and the unit incorporates a cast-in fuel crossover for balanced fuel delivery. Hidden harness wiring exits from the rear of the throttle body for a clean engine bay aesthetic. Included is a genuine Bosch wideband oxygen sensor to maintain precise fuel control.

Installation. Installation is designed to be straightforward and suitable for at-home installation with basic tools. The system requires only four main wiring connections, simplifying the wiring typically associated with EFI retrofits.

Warranty. The product comes with a standard two-year warranty, extendable through product registration.

Application. Fits universal applications with some adaptation required. This EFI system is intended for use on non-emissions controlled vehicles and is not legal for installation on emissions-controlled vehicles.
