Ask Away! with Jeff Smith: What’s the Best Rotor Tip and Terminal Spacing for my Ignition System?

Prevent Damage to Delicate AN Fittings with the Proper Tools
Wander through the pits at any drag race or examine enough cars at shows, and sooner or later you’ll find beat-up AN fittings. Some will have a few nicks and bruises.
