11-15 Degree Retard Module Kit

The MSD Ignition 11-15 Degree Retard Module Kit (MPN 8774) is a precision timing control module designed for fine-tuning ignition timing in high-performance and competition engine applications. This set of five retard modules enables users to adjust spark timing in 1-degree increments across an 11 to 15-degree retard range, giving tuners granular control over combustion timing for optimal engine response and performance across different fuel grades and operating conditions.

MSD's modular timing system allows builders and tuners to quickly swap module chips without reprogramming or complex recalibration procedures. Each module in this 5-piece kit represents a different retard value, permitting rapid on-the-fly testing and adjustment at the dyno or in the field. The compact form factor (6.1 × 1.05 × 7.8 inches) and lightweight construction (0.13 lbs) integrate seamlessly into existing MSD ignition systems. Retarding spark timing is commonly used to manage detonation on marginal fuel, reduce peak cylinder pressures under boost, or fine-tune fuel economy and emissions in controlled engine packages.

This kit is ideal for performance engine builders, dyno operators, and serious enthusiasts running MSD ignition controllers who need precise, repeatable timing adjustments without the expense or downtime of full system reprogramming. Whether dialing in a naturally aspirated street engine, tuning a turbocharged platform, or optimizing a competition build, having the full 11-15 degree range available in discrete 1-degree steps eliminates guesswork and speeds the tuning process.

MSD Ignition modules are engineered to OEM specifications and are compatible with MSD's range of digital and programmable ignition systems. Verify your specific MSD controller model supports interchangeable retard module kits before purchase to ensure proper fitment and function.
