OVERVIEW
Genuine VW/Audi internal six-lobe screw, part number N-104-707-03. This original M6 x 50 fastener is cataloged for the specified lower intake manifold attachment to the cylinder head on the S5 4.2L configuration below, from production date November 4, 2008. It also serves as the specified camshaft-bridge mounting screw on the GTI configuration listed in the fitment table.
Technical details
- Original number: N-104-707-03 / N10470703.
- Published nominal size: M6 x 50.
- Rounded head with internal six-lobe drive.
- Cataloged earlier number: N10470701.
- One screw supplied. Manifold, seals and remaining hardware are separate.
- The confirmed intake-manifold application has a production-date restriction.
The intake manifold must sit correctly against its mating cylinder-head surfaces. Its assigned mounting hardware holds the assembly in position while separate seals provide the air seal. Correct fastener length, head form and mounting location matter when renewing hardware.
A screw with an M6 thread is not automatically interchangeable with this part. The selected catalog identifies different intake-manifold hardware before November 4, 2008. Check the actual build date and original fastener number before ordering.
Common reasons to replace
Replace a missing screw, damaged threads, a rounded drive recess, visible deformation or corrosion that affects reliable assembly. Follow the factory renewal requirement after removal whenever the actual manifold service procedure specifies new hardware.
Intake-manifold removal for seal replacement or component service can expose prior tool damage, incorrect substitute screws or damaged mounting threads. Inspect each mounting point and the remaining hardware before reassembling the manifold.
Rough idle, an intake leak or a manifold-related fault requires diagnosis of the complete assembly. A new screw does not repair a cracked manifold, deteriorated gasket, faulty flap mechanism or damaged threaded hole. Do not compensate for a sealing problem by overtightening the mounting hardware.
Installation and service notes
Verify the 4.2L CAUA engine, coupe configuration, production date and assigned lower manifold position. The 3.0L Cabriolet uses a different engine arrangement and is excluded from the confirmed fitment below.
Follow the factory manifold removal and installation procedure. Protect exposed intake openings from debris while the assembly is removed. Inspect and prepare the mating surfaces, separate seals and threaded holes as directed.
Position the manifold correctly and start the screw by hand. Use a correctly fitting six-lobe driver fully engaged in the recess, then follow the specified tightening sequence for the complete manifold attachment.
Use the tightening specification for this exact engine and mounting position. Do not calculate torque from the M6 x 50 size or transfer a specification from another intake assembly. Follow any prescribed thread treatment and fastener replacement instructions.
If the screw binds, fails to seat normally or pulls the manifold out of alignment, inspect the hardware selection and mating threads before proceeding. Complete the applicable leak and functional checks after service.
This listing contains one original screw. It does not include a complete manifold hardware set, replacement intake seals or the manifold itself. Order the quantity required by the actual repair.
Fitment
| Vehicle | Model years | Engine | Configuration | Application restrictions |
|---|---|---|---|---|
| Audi S5 | 2009–2012 | 4.2L naturally aspirated V8, CAUA | B8 coupe, quattro; 6-speed manual | From production date November 4, 2008 only. Specified lower intake manifold-to-cylinder head screw. Earlier mounting hardware differs; confirm build date and original number. Excludes 3.0L S5 Cabriolet. |
| Audi S5 | 2009–2012 | 4.2L naturally aspirated V8, CAUA | B8 coupe, quattro; 6-speed automatic Tiptronic | From production date November 4, 2008 only. Specified lower intake manifold-to-cylinder head screw. Earlier mounting hardware differs; confirm build date and original number. Excludes 3.0L S5 Cabriolet. |
| Volkswagen GTI | 2010–2014 | 2.0L turbocharged gasoline TSI, CCTA/CBFA | Mk6 hatchback, front-wheel drive; Six-speed manual | Specified camshaft-bridge mounting screw. Match original N10470703 at the actual attachment. This application is separate from the S5 lower intake-manifold connection and its production-date split. |
Camshaft-bridge service: On the listed GTI, match this screw to the original bridge mounting position. Inspect the drive recess and threads and replace damaged hardware. Preserve the correct bolt sequence and the engine-specific tightening procedure when servicing the bridge; the S5 intake-manifold production split does not apply to this separate GTI attachment.
Confirm the original screw number, production date and exact lower intake-manifold attachment before ordering. One screw supplied.
