{"product_id":"the-ignition-guide-coil-boot-rod-2pack","title":"The Ignition Guide | MN158977 Coil Boot Rod Replacement (2-Pack)","description":"\u003cdiv class=\"product-narrative\"\u003e\n\u003cp\u003eA car that hesitates, misses, or idles rough is often telling you something small and specific, and among the first suspects is the ignition coil boot, the quiet connector that carries the spark to the plug. When that boot hardens or cracks, spark energy leaks, and the engine lets you know. The Ignition Guide replaces the worn part with a fresh component engineered to restore clean, reliable delivery to the cylinder.\u003c\/p\u003e\n\u003cp\u003eBuilt to match the original geometry of the factory part, this two-pack is ready for the common MN158977 family of coil boots used across a range of Mitsubishi and Dodge models. It seats properly over the coil and spark plug, restores the insulating seal the old part has lost, and goes in with the same tools you would use on the original, making it a straightforward service you can handle in the garage.\u003c\/p\u003e\n\u003cp\u003eWe made The Ignition Guide for the people who keep their car on the road with their own hands and for shops that want a dependable, correctly-spec part on the shelf. A fresh boot can smooth out a rough idle, clear up an intermittent miss, and stop the slow breakdown that a neglected coil boot causes over time.\u003c\/p\u003e\n\u003cp\u003eWe also believe a serviceable part should be easy to source when you need it, which is why this pair arrives ready for the workbench and clearly referenced to the factory numbers, so you can confirm fitment before you even open the tool drawer. Keeping a spare on the shelf means a rough idle or an intermittent miss does not have to end your weekend. For the home mechanic and the working shop alike, having the right small part at the right moment is worth far more than its price.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eThis is not just a rubber boot. It is the quiet insulator that keeps the spark exactly where the engine needs it.\u003c\/em\u003e\u003c\/p\u003e\n\u003c\/div\u003e\u003chr style=\"margin:20px 0;border:0;border-top:1px solid #eee;\"\u003e\u003cdiv class=\"product-features\"\u003e\n\u003ch3\u003eKey Features\u003c\/h3\u003e\n\u003cul style=\"list-style:none;padding:0;\"\u003e\n\u003cli\u003e✦ Correctly-spec replacement for the common MN158977 coil boot family\u003c\/li\u003e\n\u003cli\u003e✦ Restores spark insulation that cracked or hardened boots lose over time\u003c\/li\u003e\n\u003cli\u003e✦ Fresh seating surfaces for clean coil-to-plug energy delivery\u003c\/li\u003e\n\u003cli\u003e✦ Two boots per pack, so you have the next service covered\u003c\/li\u003e\n\u003cli\u003e✦ Designed to match original factory geometry and fit\u003c\/li\u003e\n\u003cli\u003e✦ Straightforward replacement with standard hand tools\u003c\/li\u003e\n\u003cli\u003e✦ Helps smooth rough idle and intermittent misfire tendencies\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003cdiv class=\"product-specs\"\u003e\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003cul style=\"list-style:none;padding:0;\"\u003e\n\u003cli style=\"border-bottom:1px solid #eee;padding:8px 0;\"\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Ignition coil boot \/ rod replacement\u003c\/li\u003e\n\u003cli style=\"border-bottom:1px solid #eee;padding:8px 0;\"\u003e\n\u003cstrong\u003eReference No.:\u003c\/strong\u003e MN158977 \/ 099700-0480 \/ SPP55E \/ IIS250\u003c\/li\u003e\n\u003cli style=\"border-bottom:1px solid #eee;padding:8px 0;\"\u003e\n\u003cstrong\u003eQuantity:\u003c\/strong\u003e 2 pieces per pack\u003c\/li\u003e\n\u003cli style=\"border-bottom:1px solid #eee;padding:8px 0;\"\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Selected Mitsubishi and Dodge model families (verify fit)\u003c\/li\u003e\n\u003cli style=\"border-bottom:1px solid #eee;padding:8px 0;\"\u003e\n\u003cstrong\u003eFunction:\u003c\/strong\u003e Insulating connector between ignition coil and spark plug\u003c\/li\u003e\n\u003cli style=\"border-bottom:1px solid #eee;padding:8px 0;\"\u003e\n\u003cstrong\u003eRequired Tools:\u003c\/strong\u003e Standard hand tools, same as original service\u003c\/li\u003e\n\u003cli style=\"border-bottom:1px solid #eee;padding:8px 0;\"\u003e\n\u003cstrong\u003eInstall Difficulty:\u003c\/strong\u003e Moderate, suitable for DIY garage work\u003c\/li\u003e\n\u003cli style=\"border-bottom:1px solid #eee;padding:8px 0;\"\u003e\n\u003cstrong\u003eEffect:\u003c\/strong\u003e Restores spark delivery, smoother idle, fewer misfires\u003c\/li\u003e\n\u003cli style=\"border-bottom:1px solid #eee;padding:8px 0;\"\u003e\n\u003cstrong\u003eCare During Install:\u003c\/strong\u003e Keep sealing surfaces clean and dry\u003c\/li\u003e\n\u003cli style=\"border-bottom:1px solid #eee;padding:8px 0;\"\u003e\n\u003cstrong\u003ePackage Includes:\u003c\/strong\u003e 2 x coil boot rod\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003c\/div\u003e\u003cdiv class=\"product-applications\"\u003e\n\u003ch3\u003eApplication Scenarios\u003c\/h3\u003e\n\u003cp\u003eReach for The Ignition Guide when a familiar engine starts idling rough, hesitating under load, or throwing an ignition-related code, and the coil boots are due for inspection.
