Because the rear bank of cylinders sits tightly against the firewall, ambient underhood temperatures soar, leading to premature breakdown of the internal epoxy and primary windings. When these stock coils begin to fail, the engine experiences weak spark delivery. This translates to noticeable hesitation under acceleration, rough idling, decreased fuel economy, and dreaded P0300-series misfire codes. The OEM components simply lack the thermal resistance required for sustained high-temperature operation over high mileage.\u003c\/p\u003e\n  \n  \u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n  \u003cp\u003eThis UF414 high-performance coil pack set is engineered to resolve the thermal degradation issues inherent to the factory setup. Featuring high-grade copper wire for both primary and secondary windings, these coils maximize voltage output to the spark plugs for a more complete burn and improved throttle response. The housings are constructed from a dense, heat-resistant dielectric polymer, reinforced with specialized internal epoxy that prevents voltage leaks and withstands extreme engine bay temperatures. By delivering a hotter, more consistent spark, these upgraded coils prevent spark blowout under heavy load, stabilize idle characteristics, and fully restore the 300-horsepower potential of the LS4 engine.\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;\"\u003e2008-2009 Buick LaCrosse\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;\"\u003e5.3L LS4 V8 \/ W-Body\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;\"\u003e300 hp \/ 323 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;\"\u003eUF414\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003c\/table\u003e\n \n  \u003ch3\u003eCompatibility\u003c\/h3\u003e\n  \u003cul\u003e\n    \u003cli\u003e2008 Buick LaCrosse Super 5.3L V8\u003c\/li\u003e\n    \u003cli\u003e2009 Buick LaCrosse Super 5.3L V8\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003ch3\u003eThe Buick Muscle Caliber\u003c\/h3\u003e\n  \u003cp\u003eFor V8-powered GM sedans, maintaining precise ignition timing and powerful spark delivery is non-negotiable.
