These internal ridges create air pockets and boundary layer separation, which increases the friction coefficient of the intake charge and slows velocity. Furthermore, the factory plastic sound chambers are undersized and tuned primarily for noise suppression rather than resonant quality, resulting in a muffled engine note and restricted volume in the upper RPM range where the Ferrari-derived V8 thrives. Over time, the factory rubber snorkel is also prone to heat soak and potential structural softening.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis URUTU upgrade utilizes multi-layer reinforced silicone with a high-gloss, smooth internal bore, significantly reducing drag and optimizing airflow directly into the throttle body. The kit includes dual oversized sound chambers fabricated from high-grade carbon fiber. These chambers offer increased internal volume compared to stock, enhancing the natural induction acoustic profile of the 4.2L and 4.7L engines while providing superior thermal resistance against engine bay heat soak. To ensure a leak-proof seal, the kit provides USA-made Murray Gold-Seal clamps and German-engineered NORMA hose clamps, ensuring structural integrity under high vacuum conditions. Note: This configuration is specifically for models utilizing a single (01) vacuum line inlet.\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;\"\u003e2008-2020 Maserati GranTurismo\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;\"\u003eF136U, F136Y \/ M145\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;\"\u003e405-460 hp \/ 339-384 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;\"\u003eN\/A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2008-2019 Maserati GranTurismo 4.2L F136U V8\u003c\/li\u003e\n  \u003cli\u003e2008-2020 Maserati GranTurismo 4.7L F136Y V8\u003c\/li\u003e\n  \u003cli\u003eFits GranTurismo S, MC, and Sport trims with single vacuum inlet\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Maserati European Precision Standard\u003c\/h3\u003e\n\u003cp\u003eEngineered specifically for the F136 engine family, this intake modification maintains factory sensor calibration to ensure no CEL (Check Engine Light) issues.
