Coil Driver Module - Sniper EFI

The Coil Driver Module - Sniper EFI from Holley is a single-channel ignition control module engineered for precision spark timing in modern fuel-injected powerplants. Designed for builders and engine tuners who demand reliable, repeatable ignition control, this module integrates seamlessly into Sniper EFI systems to manage coil firing with electronic precision. Whether you're upgrading a carbureted platform to EFI or fine-tuning an existing fuel-injection setup, the Sniper EFI coil driver delivers the predictable spark delivery critical for consistent combustion and optimal performance across varying load conditions.

This ignition control module operates as the bridge between the Sniper EFI engine management computer and your ignition coil, translating digital timing commands into high-current switching events that fire each cylinder on demand. The single-channel architecture is built for straightforward installation in naturally aspirated and moderately boosted applications where individual coil management ensures stable idle quality, smooth throttle response, and extended ignition dwell times at higher RPM. Complete wiring harness inclusion eliminates guesswork during installation, and the compact footprint (3.3 x 2.3 x 5.7 inches) allows flexible mounting in tight engine bays without sacrificing accessibility for tuning or diagnostics.

Street applications, restorations, and dedicated road-race builds benefit most from this module's universal compatibility with Sniper EFI systems and standard 12-volt ignition architectures. Installers appreciate the included wiring harness, which reduces labor time and eliminates custom fabrication errors that compromise spark delivery. The Coil Driver Module - Sniper EFI is ideal for anyone upgrading to or troubleshooting a Holley EFI platform, delivering bulletproof spark control that pairs perfectly with fuel-injection tuning for maximum power output and reliability.
