The naturally aspirated \u003cstrong\u003eMZR 2.3L (L3-VE)\u003c\/strong\u003e engine subjects factory ignition assemblies to high cylinder head temperatures, degrading the silicone boots and breaking down internal epoxy insulation. Over time, micro-cracks cause secondary winding resistance drift, resulting in spark blowout, rough cold starts, and random misfire codes (DTC P0300–P0304). Worn standard plugs further strain tired coil packs, accelerating unburned fuel wash across downstream catalysts.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis comprehensive ignition service kit resolves secondary ignition collapse by matching heavy-duty pencil coils with high-conductivity fine-wire iridium spark plugs. The replacement coils feature reinforced thermoplastic housings, vacuum-potted high-dielectric epoxy, and low-resistance copper windings that maintain steady dwell times under load without thermal degradation. Paired with laser-welded iridium center electrodes that minimize electrical quench and resist electrode erosion, this kit ensures rapid flame kernel propagation, razor-sharp throttle response, and reduced fuel consumption across the factory operating band.\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; margin-bottom: 20px;\"\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eFitment\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e2006-2007 Mazda 5\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eEngine \/ Chassis\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eMZR 2.3L (L3-VE)\u003c\/strong\u003e \/ \u003cstrong\u003eCR\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eStock Output\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e157 hp \/ 148 lb-ft\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr\u003e\n\u003cth style=\"padding:10px; text-align: left; border: 1px solid #e0e0e0;\"\u003eReplaces OEM Part #\u003c\/th\u003e\n\u003ctd style=\"padding:10px; border: 1px solid #e0e0e0;\"\u003e\n\u003cstrong\u003eLFB618100C9U\u003c\/strong\u003e, \u003cstrong\u003eUF541\u003c\/strong\u003e, 5C1741, \u003cstrong\u003eLFB618100C\u003c\/strong\u003e, C779, COP271, GN10400, 1788395, U5204, 48736\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2006 Mazda 5 Sport (2.3L L4 Gas)\u003c\/li\u003e\n  \u003cli\u003e2006 Mazda 5 Touring (2.3L L4 Gas)\u003c\/li\u003e\n  \u003cli\u003e2006 Mazda 5 Grand Touring (2.3L L4 Gas)\u003c\/li\u003e\n  \u003cli\u003e2007 Mazda 5 Sport (2.3L L4 Gas)\u003c\/li\u003e\n  \u003cli\u003e2007 Mazda 5 Touring (2.3L L4 Gas)\u003c\/li\u003e\n  \u003cli\u003e2007 Mazda 5 Grand Touring (2.3L L4 Gas)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eDoes this fit the CR 5?\u003c\/strong\u003e\u003cbr\u003e Yes, this is a direct fit for the 2006-2007 Mazda 5 equipped with the \u003cstrong\u003eMZR 2.3L (L3-VE)\u003c\/strong\u003e engine.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAre the iridium plugs pre-gapped for this application?\u003c\/strong\u003e\u003cbr\u003e Yes, the spark plugs come pre-gapped to factory specification, though checking clearance with a non-contact wire gauge prior to torquing is recommended.\u003c\/p\u003e\n\n\u003ch3\u003eThe Mazda Performance Caliber\u003c\/h3\u003e\n\u003cp\u003eMazda naturally aspirated platforms demand consistent spark delivery to maintain optimal thermal efficiency and linear power.
