Over time, internal epoxy insulation deteriorates, resulting in micro-arcing, secondary resistance variations, and high-rpm spark blowout. Coupled with eroded standard plug electrodes, this leads to hesitation under load, erratic idle oscillation, reduced thermal efficiency, and intermittent P0300-P0304 misfire codes.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive service kit pairs four heavy-duty coil-on-plug packs with four matched iridium spark plugs. The ignition coils feature high-conductivity internal electrolytic copper windings paired with high-temperature epoxy potting to resist thermal cycling and electrical leakage. The iridium plugs offer a low-voltage-demand, laser-welded center electrode that ensures stable flame kernel propagation, superior anti-fouling characteristics, and consistent dielectric strength under high compression.\u003c\/p\u003e\n\n\u003ch3\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ctable width=\"100%\" style=\"border-collapse: collapse; border: 1px solid #e0e0e0; font-size: 14px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eFitment\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e2013-2019 Nissan Sentra\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eEngine \/ Chassis\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e1.8L MRA8DE \/ B17\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eStock Output\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003e130 hp \/ 128 lb-ft (Approx)\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eUF549, UF-549\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2013-2019 Nissan Sentra (S, SV, SL, SR, FE+ S, FE+ SV) 1.8L L4 Gas (MRA8DE Engine)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Nissan Precision Standard\u003c\/h3\u003e\n\u003cp\u003eDesigned to restore crisp throttle response, clean combustion cycles, and reliable cold starts, this ignition system kit eliminates misfires without triggering check engine lights or ECU mapping errors on your daily commute.\u003c\/p\u003e","brand":"VelocityMax","offers":[{"title":"Default Title","offer_id":50452224475384,"sku":"DS-ECQWQ56KJ","price":78.95,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0800\/1290\/2648\/files\/ignition-coil-and-iridium-spark-plugs-for-nissan-sentra-2013-2019-1-8l-1.jpg?v=1788721204","url":"https:\/\/performancechiptuning.com\/products\/ignition-coil-and-iridium-spark-plugs-for-nissan-sentra-2013-2019-1-8l","provider":"Performance Chip Tuning","version":"1.0","type":"link"}
