OVERVIEW
Genuine VW/Audi intake manifold bolt, part number N-910-973-01. This original fastener secures the intake manifold to the cylinder head at the prescribed mounting position. Its published nominal size is M6 x 45 mm. One bolt is supplied.
Technical details
- Original number: N-910-973-01 / N91097301.
- Published nominal thread diameter and length: M6 x 45 mm.
- Rounded head with internal drive recess, as pictured.
- Assigned application: intake manifold-to-cylinder-head attachment.
- Intake manifold, seals, studs, nuts and other bolts are separate.
The manifold attachment maintains the prescribed assembled joint at the cylinder head. The bolt does not provide the intake port seal by itself; the correct manifold sealing components and the condition of the mating surfaces remain essential.
Different manifold positions can use different hardware. Confirm the original bolt number and length at the position being serviced rather than choosing a fastener only by its thread diameter. This listing supplies a single bolt rather than a manifold installation kit.
Common reasons to replace
Inspect this bolt when removing the intake manifold for manifold replacement, intake port cleaning or access to surrounding components. Replace damaged threads, a rounded internal drive, a visibly bent shank or corrosion affecting proper installation. Follow factory instructions when removed hardware must be renewed.
Previous repairs may leave an incorrect fastener, a missing bolt or damage caused by an improperly fitting tool. Check the original part number and mounting position before ordering. A similar-looking screw is not sufficient confirmation of the required length or bearing arrangement.
If the manifold joint is loose or leaking, inspect the complete connection. A new bolt cannot repair a cracked manifold, stripped cylinder-head threads, damaged sealing components or incorrect manifold alignment. Diagnose the actual condition before replacing parts.
Air leaks, rough running or intake-related fault codes can have several causes. Do not assume that a fastener alone resolves a manifold actuator, sensor, hose or sealing problem. Inspect the affected components and follow the appropriate diagnosis.
Installation and service notes
Follow the factory procedure for the exact engine code and installed manifold. Identify the assigned fastener positions before removal and keep bolts, studs and nuts organized. Protect open intake ports from debris throughout the service.
Inspect the manifold, sealing surfaces and threaded mounting points before assembly. Replace seals and other components as prescribed. Repair damaged threads using the appropriate factory method rather than forcing this bolt into an impaired mounting point.
Seat and align the manifold correctly before tightening its hardware. Do not use the bolt to pull an obstructed or misaligned manifold into place. Check for trapped hoses, connectors or other components that can interfere with normal assembly.
Start the bolt by hand at its designated position. Use the correct fitting bit for the internal drive recess and keep the tool aligned with the bolt. Stop if the bolt binds before seating and recheck the hole, alignment and part selection.
Use the engine-specific tightening sequence and specified torque. No general torque figure is provided because the correct procedure depends on the installed manifold and engine arrangement. Apply lubricant or thread locking compound only when the factory procedure calls for it.
After assembly, reconnect and check the hoses, electrical connections and components disturbed during removal. Perform the prescribed leak and operating checks for the repair. Confirm that all required manifold attachment hardware is present.
For aftermarket manifolds or modified intake systems, verify their hardware requirements separately. The nominal M6 x 45 mm size does not establish compatibility with every intake assembly. Order the required quantity for the specific positions being serviced.
