These factory components create significant internal turbulence and are prone to heat soak, as the plastic absorbs engine bay heat, warming the incoming air charge. This thermal inefficiency results in a less dense oxygen mixture, hindering combustion and limiting the throttle response of the 3.5L V6. Additionally, the standard paper filters provide high resistance and are non-reusable, increasing long-term maintenance costs and limiting volumetric efficiency at higher RPMs.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis system features CNC-mandrel-bent T-6061 billet aluminum piping, providing a smooth internal bore to minimize laminar drag and maximize air velocity toward the throttle body. The aluminum construction is treated with a scratch-resistant coating for thermal durability and structural integrity under high vacuum. By utilizing a high-flow, washable micro-cotton cone filter, the system significantly increases the available surface area for filtration while lowering the pressure drop across the intake. The design specifically accommodates the OEM rectangular mass airflow (MAF) sensor connection, ensuring precise air-fuel ratio readings. This modification allows the VQ35DE to breathe more freely, effectively reducing pumping losses and improving thermal management.\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;\"\u003e2002-2006 Nissan Altima, Maxima\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;\"\u003eVQ35DE \/ L31, A34\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;\"\u003e240-265 hp \/ 246-255 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\u003e2002-2006 Nissan Altima (3.5L V6 Models Only)\u003c\/li\u003e\n  \u003cli\u003e2004-2005 Nissan Maxima (3.5L V6 Models Only)\u003c\/li\u003e\n  \u003cli\u003e[ Please Note: This Air intake fits models with OEM rectangular air mass sensors connection slots only ]\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eThe Nissan VQ-Series Standard\u003c\/h3\u003e\n\u003cp\u003eThe Nissan VQ-series engines are engineered for high-revving performance and a distinct acoustic profile.
