With variable pitch winding, they deliver ultra-low resistance, creating a spark so powerful it's like fireworks for your cylinders. But that's not all – these leads are also champs at noise suppression, keeping EMI/RFI interference at bay. Numbered for easy cylinder identification and color-coded for a straightforward installation, they're like the paint-by-numbers of engine maintenance. Plus, the positive-locking, corrosion-resistant stainless steel terminal ends mean these leads are in it for the long haul, resisting vibration and separation. And to top it off, the high-temp silicone outer jacket laughs in the face of moisture, oil, and temperature extremes, making sure these leads are built to last.
