Edelbrock 3674 E-Street 2 EFI Ignition Control Kit for Chevy

The Edelbrock 3674 is a plug-and-play E-Street 2 EFI Ignition Control Kit designed specifically for Chevrolet small block and big block V8 engines. This kit unlocks the full ignition timing control capabilities of the Edelbrock E-Street 2 EFI system, giving tuners complete, software-driven authority over ignition advance without ever disassembling the distributor.

Key Features:

• Plug-and-play Pro-Flo EFI distributor with a special Hall Effect pickup and trigger wheel pattern engineered exclusively for Edelbrock EFI systems
• Full ignition curve control via the free Edelbrock E-Tuner app — adjust timing on the fly from your Android phone or tablet over Bluetooth
• Eliminates mechanical advance limitations — no springs, weights, or vacuum cans to manage; timing is fully software-controlled
• Direct coil drive capability — the E-Street 2 EFI ignition output fires an inductive coil directly without requiring a CDI box (coil primary resistance must be 0.7 ohms or higher)
• Includes the Edelbrock Pro-Flo EFI distributor, ignition coil harness, and distributor adapter harness
• Compatible with Chevy small block and big block V8 applications

Performance Benefits:

• Smoother idle quality
• Improved throttle response and acceleration
• Better peak power output
• Enhanced fuel economy
• Precise detonation control

Important Notes: This ignition control kit is exclusively compatible with Edelbrock E-Street 2 EFI systems and will not work with the original E-Street systems (part numbers 3600, 3602, or 3606). The ignition control feature is an optional add-on and is not required for the E-Street 2 EFI to operate. For medium- to high-performance applications, use of a CDI box is recommended alongside this kit.
