Confirm your manifold model before ordering. Fits all Honda\/Acura B-series engines: B16A, B16B, B18C (GSR\/ITR), B18B1 (LS\/RS).\u003c\/p\u003e\n\u003c\/div\u003e\n\n\u003cp\u003eWhether you took your manifold apart, stripped out a bolt, ripped a gasket, or simply lost a fitting — this complete hardware kit includes everything that came with your Skunk2 Ultra Race Centerfeed manifold when new. Gaskets, mounting hardware, fittings, and all ancillary fasteners in one kit. 1.1 lbs. Ships fast across Canada and the US.\u003c\/p\u003e\n\n\u003ch3\u003eWhat’s Included\u003c\/h3\u003e\n\u003cp\u003eThe 907-05-9080 contains the complete original hardware complement for the Ultra Race Centerfeed manifold:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntake manifold-to-head gasket:\u003c\/strong\u003e The primary sealing gasket between the Ultra Race Centerfeed’s runner outlets and the B-series cylinder head intake ports. This gasket is the most commonly needed replacement item — it should not be reused after removal, and any manifold disassembly for porting, cleaning, or repair requires a fresh gasket for reassembly. Using a damaged or improperly seated intake gasket on the B-series results in vacuum leaks that cause idle instability, lean fuelling, and reduced power.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManifold mounting bolts\/studs and hardware:\u003c\/strong\u003e The fasteners securing the manifold to the B-series cylinder head. Stripped manifold studs are a common consequence of over-torquing on aluminium heads — the kit provides OEM-equivalent replacement fasteners to the correct specification for the Ultra Race manifold.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThrottle body gasket:\u003c\/strong\u003e Sealing gasket between the throttle body inlet and the Ultra Race Centerfeed plenum opening. A vacuum leak at the throttle body flange is a frequent source of idle and fuelling issues on B-series builds — replacing this gasket during any throttle body service is good practice.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVacuum and PCV fittings:\u003c\/strong\u003e The barbed fittings for vacuum source ports (brake booster, MAP sensor, FPR reference, IACV, etc.) and PCV routing. Aluminium fittings can corrode, seize, or strip on older B-series builds — having replacements on hand is essential for a clean manifold rebuild.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant bypass and IAC fittings (where applicable):\u003c\/strong\u003e Fittings for idle air control and coolant bypass passages as configured on the Ultra Race Centerfeed’s port layout.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdditional fasteners and hardware:\u003c\/strong\u003e All remaining bolts, washers, and miscellaneous hardware required to fully assemble the manifold to factory-new specification.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhen You Need This Kit\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManifold disassembly:\u003c\/strong\u003e Any removal of the Ultra Race Centerfeed from the B-series head requires a new manifold gasket for reassembly. If the manifold has been off the car — for head work, porting, engine swap, or cleaning — this kit provides the gaskets and hardware for a clean, leak-free reinstall.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStripped or damaged fasteners:\u003c\/strong\u003e Aluminium cylinder heads are susceptible to stripped threads from over-torqued or corroded manifold studs. The replacement hardware in this kit allows correct-specification reinstallation without sourcing individual fasteners from Skunk2 separately.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLost or damaged fittings:\u003c\/strong\u003e Vacuum fittings on B-series manifolds see years of heat cycling, removal, and reinstallation. Cracked, seized, or missing fittings cause vacuum leaks that are disproportionately difficult to diagnose. A complete fitting set eliminates the need to source individual sizes.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEngine swap completion:\u003c\/strong\u003e B-series swaps into EG\/EK Civic, DC2 Integra, and other chassis frequently involve sourcing a used Ultra Race manifold. Used manifolds often arrive incomplete or with damaged hardware. The 907-05-9080 restores a used manifold to complete, new-hardware specification.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBuild documentation:\u003c\/strong\u003e Keeping a hardware kit on the shelf during a B-series build avoids delays caused by a single missing fastener or gasket. At $161 for the complete set, this is straightforward insurance against a stripped bolt holding up an engine bay completion.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eB-Series Application Coverage\u003c\/h3\u003e\n\u003cp\u003eThe Ultra Race Centerfeed manifold and this hardware kit fit all Honda\/Acura B-series DOHC engines:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eB16A \/ B16A2 \/ B16A3 — Honda Civic Si (EG6, EK4), Del Sol VTEC, JDM Civic SiR\u003c\/li\u003e\n\u003cli\u003eB16B — Honda Civic Type R (EK9, JDM)\u003c\/li\u003e\n\u003cli\u003eB18C1 — Acura Integra GSR (DC2\/DB8, 1994–2001)\u003c\/li\u003e\n\u003cli\u003eB18C5 — Acura Integra Type R (DC2, 1997–2001)\u003c\/li\u003e\n\u003cli\u003eB18B1 — Acura Integra LS\/RS (DC2\/DB8, 1994–2001)\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe hardware kit is manifold-specific — confirm your manifold is the Ultra Race Centerfeed variant before ordering.
