The factory plenum volume is excessively small, and the runners are relatively narrow and rough-cast, which chokes airflow velocity past 5,500 RPM. This creates a severe bottleneck for modified engines, limiting mid-range torque and stifling top-end horsepower gains. Furthermore, the stock 55mm to 56mm throttle body opening becomes a significant restriction when introducing aggressive cam profiles or forced induction, inducing pressure drops that rob the engine of its breathing capacity and throttle response.\u003c\/p\u003e\n\n\u003ch3\u003eThe Engineering Solution\u003c\/h3\u003e\n\u003cp\u003eThis performance intake manifold addresses these OEM airflow limitations through a completely redesigned, high-volume plenum and optimized, short-runner architecture. Manufactured from premium, heat-dissipating cast aluminum, it maximizes the venturi effect to force high-velocity air into the combustion chambers. The manifold features an oversized 66mm throttle body opening—which can be safely port-matched up to 70mm—allowing for massive improvements in intake charge volume. By combining this larger plenum with smoother runner transitions, the manifold delivers profound increases in mid-range torque and aggressive top-end power, effectively eliminating the factory choke point for serious naturally aspirated or turbocharged D-Series builds.\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;\"\u003e1988-2000 Honda Civic\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;\"\u003eD-Series (D15\/D16) \/ EF, EG, EK\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;\"\u003e108-127 hp \/ 100-107 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\u003e1988-2000 Honda Civic (CX, DX, EX, GX, HX, LX)\u003c\/li\u003e\n  \u003cli\u003e1993-1997 Honda Civic del Sol (S, Si)\u003c\/li\u003e\n  \u003cli\u003e1988-1991 Honda CRX (Base, HF, Si)\u003c\/li\u003e\n  \u003cli\u003e1987 Honda Wagovan (DX)\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCompatible Engine Codes:\u003c\/strong\u003e Honda D15A2, B1, B2, B6, B7, B8, Z1 and D16A6, Y7, Y8, Z6\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eFitment Note 1:\u003c\/strong\u003e Not compatible with OEM D-series throttle body.
