MAGNUM Spark Plug Wires - Blue - FLT 3033B

Your ignition system is only as reliable as the wires delivering spark to the cylinders. MAGNUM Spark Plug Wires replace worn or degraded ignition wires with precision-engineered components that eliminate misfire, improve cold-start performance, and ensure consistent ignition timing across all cylinders. Built specifically for Harley-Davidson motorcycles, these wires integrate seamlessly with your bike's electrical architecture while rejecting the electromagnetic interference that plagues older designs.

The heavy-walled FEP fluoropolymer insulation and suppression conductor core deliver voltage without signal noise—critical for keeping your fuel injection and engine management systems running clean. Backed by domestic manufacturing and engineered for extreme duty, MAGNUM wires are the upgrade serious riders choose when OEM replacements won't cut it.
