{"title":"Ignition \u003e Hardware, Fasteners and Fittings","description":"\u003cp\u003eIgnition hardware, fasteners, and fittings are the components that hold your ignition system together and keep high-voltage signals moving where they need to go. Distributor caps and coil boots — which make up the bulk of the 651 parts here — are wear items that degrade from heat cycling, carbon tracking, and moisture intrusion. Distributor caps typically need replacement every 30,000–50,000 miles on older cap-and-rotor systems; coil boots on COP setups often go 60,000–100,000 miles before cracking or arcing. Diesel glow plugs follow their own schedule, usually every 100,000 miles or at the first sign of hard cold-starts. When buying, prioritize correct terminal count and cap diameter for your distributor, and verify boot ID and overall length against your coil tower — fitment varies significantly between makes. OEM-spec silicone coil boots outperform generic rubber in high-heat engine bays.\u003c\/p\u003e\n\n\u003ch3\u003eSigns you need replacement\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eEngine misfires or rough idle at operating temperature.\u003c\/strong\u003e Carbon tracking inside a distributor cap creates a conductive path that bleeds spark to the wrong cylinder or to ground — rough idle and misfires that worsen under load are classic symptoms.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHard starting or extended cranking in cold weather.\u003c\/strong\u003e On diesel engines, a failed or weak glow plug can't bring the combustion chamber to ignition temperature, making cold starts difficult or impossible below 40°F.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCracked, brittle, or oil-soaked coil boot.\u003c\/strong\u003e A coil boot that's hardened, split, or saturated with oil can arc to the valve cover instead of the plug, causing a cylinder-specific misfire and often triggering a P030X code.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eVisible carbon tracks or corrosion inside the distributor cap.\u003c\/strong\u003e White or gray residue between terminals, or a black burn line on the cap's interior, means high-voltage is tracking across the surface — replace before it causes a no-start.\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eIgnition switch doesn't return or sticks in the start position.\u003c\/strong\u003e A worn ignition switch actuator pin can prevent the switch from cycling correctly, leading to a starter that keeps engaging or a key that won't return to the run position.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently asked questions\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHow often should distributor caps and rotors be replaced?\u003c\/strong\u003e\n  On most vehicles with a conventional distributor, replace the cap and rotor together every 30,000–50,000 miles as part of a tune-up. High-performance or high-mileage engines running in humid climates may need replacement sooner — inspect annually for carbon tracking, cracks, or corroded terminals.\u003c\/li\u003e\n\n  \u003cli\u003e\n\u003cstrong\u003eAre aftermarket coil boots as good as OEM on COP ignition systems?\u003c\/strong\u003e\n  Quality varies significantly. Look for boots made from high-temp silicone rated above 500°F, with a snug interference fit on your specific coil tower diameter. Budget rubber boots can harden and crack within 20,000 miles. OEM or OEM-equivalent silicone boots from brands like Standard Motor Products or Denso are worth the modest price difference.\u003c\/li\u003e\n\n  \u003cli\u003e\n\u003cstrong\u003eWhat else should I replace when swapping out a distributor cap?\u003c\/strong\u003e\n  Always replace the distributor rotor at the same time — they wear as a pair. It's also smart to install fresh spark plug wires if yours have more than 50,000 miles on them. The complete job on a typical V8 runs $40–$120 in parts and takes about 30–45 minutes with basic hand tools.\u003c\/li\u003e\n\u003c\/ul\u003e","products":[{"product_id":"delphi-dc1015-distributor-cap","title":"Delphi DC1015 Distributor Cap","description":"\u003ch2\u003eDelphi DC1015 Distributor Cap for HEI Ignition\u003c\/h2\u003e\u003cp\u003eThe Delphi DC1015 is a standard replacement distributor cap for HEI ignition systems.
