Description

Precise timing control—Holley EFI dual-sync distributors are built with two Hall effect sensors for crankshaft and camshaft signals. The distributors can be used as just a crankshaft speed input or provide a camshaft sync signal for sequential fueling operation. They're also useful for crank and cam signals when running coil-on-plug applications. Dozens of models are available; order the one recommended for your vehicle/engine application.

Some features of Holley EFI dual-sync distributors include:

* CNC-machined billet aluminum housings with integrated LEDs for easy setup
* Hardened steel distributor gear
* Precision-machined shutter wheels that ensure accurate timing—even at very high RPM
* Designed to be plug-and-play with Holley systems, but may be used with other EFI systems that support Hall effect crankshaft and camshaft sensors
* Housings are available in a variety of finishes
