MSD 6TN/6ALN NASCAR CD Ignitions

These MSD 6TN and 6ALN ignitions are the ultimate choices for superior performance in harsh racing conditions. With sturdy vibration mounts and CD circuits encased in a clear 2-part silicone elastomer, they are virtually vibration-proof. A specially designed, weathertight, 6-pin connector meets NASCAR's 20-6.1 ignition wiring rule and provides a tight, positive-locking connection with individual seals to keep dirt and moisture from each connection. The 6TNs are equipped with a special 4-pin connector that plugs directly into an MSD soft touch rev control, while the 6ALNs have a built-in rev control. These rev controls are adjustable with plug-in modules and will save your engine from overrev damage caused by missed shifts or driveline failures. They'll work with virtually any 4, 6 (even-fire V6 only), or 8-cylinder engines. Show Less
