Built with a 3‑ohm primary winding and a round oil‑filled canister, it’s optimized for PerTronix Ignitor systems while remaining broadly compatible with many inductive distributors. The design emphasizes heat management and steady spark delivery for street use when installed vertically with the terminal facing up.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this coil affect throttle response and combustion?\u003c\/h3\u003e\n\u003cp\u003eStronger secondary voltage helps the spark bridge the gap under load and burn the air\/fuel mixture more completely.
