These OEM components are highly susceptible to heat soak—a condition where the plastic air box absorbs ambient engine bay heat, significantly increasing intake air temperatures. Higher IATs lead to decreased oxygen density, which triggers the ECU to retard ignition timing, effectively reducing power output during sustained operation. Furthermore, the stock corrugated rubber bellows create significant internal turbulence, disrupting the laminar flow required for optimal volumetric efficiency in the high-revving K-Series platform.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis induction kit utilizes lightweight, mandrel-bent T-304 aluminum piping to provide a smooth internal surface that minimizes friction and maximizes air velocity. Unlike the stock plastic, the T-304 aluminum construction combined with the included heat shield effectively isolates the intake charge from the radiant heat generated by the 2.4L engine block and radiator. The system features a reusable high-flow conical filter that increases the available surface area for air filtration compared to the flat paper OEM panel. This configuration allows the engine to draw a denser, cooler air charge, resulting in increased explosive output and a more pronounced induction sound under load.\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;\"\u003e2004-2008 Acura TSX\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;\"\u003eK24A2 \/ CL9\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;\"\u003e~200 hp \/ 166 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;\"\u003eDR109\u003c\/td\u003e\n\u003c\/tr\u003e\n  \u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"padding:8px;\"\u003e\u003cstrong\u003eMaterial\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd style=\"padding:8px;\"\u003eT-304 Aluminum \/ Steel Heat Shield\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eCompatibility\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e2004 Acura TSX 2.4L Engine\u003c\/li\u003e\n  \u003cli\u003e2005 Acura TSX 2.4L Engine\u003c\/li\u003e\n  \u003cli\u003e2006 Acura TSX 2.4L Engine\u003c\/li\u003e\n  \u003cli\u003e2007 Acura TSX 2.4L Engine\u003c\/li\u003e\n  \u003cli\u003e2008 Acura TSX 2.4L Engine\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Acura Performance Standard\u003c\/h3\u003e\n\u003cp\u003eAs a staple of the JDM tuning scene, the Acura TSX K24 platform thrives on improved breathing.
