X AUTOHAUX Fuel Injector Seal Repair Kit for Audi & VW 6-Set — 2.8L/3.2L V6 V8 Direct-Fit (06E998907G)

X AUTOHAUX 6-set fuel injection valve seal repair kit replaces worn injector seals and associated caps to stop leaks, reduce fuel odor, and restore proper injector seating on compatible Audi and VW V6/V8 engines.

This repair kit provides the common replacement parts needed when fuel injector seals and pintle caps degrade on 2.8L and 3.2L Audi V6/V8 engines and select Volkswagen Touareg models. The set is engineered as a direct-fit service kit for OEM part numbers 06E998907, 06E998907E, 06E998907G and 06E906036P. It includes upper and lower sealing components and retaining caps so you can perform a complete injector-top refresh without sourcing multiple individual pieces.

Which models and engines will these seals fit?

This kit is intended for Audi A4, A5, A6, A8, Q7 and Volkswagen Touareg applications with the relevant 2.8L/3.2L V6 or V8 engines produced across the listed years. Fitment varies by engine code and production year, so always check engine specifications before purchase.

• Compatible with part numbers: 06E998907, 06E998907E, 06E998907G, 06E906036P.
• Works for many Audi A4/A5/A6/A8/Q7 and VW Touareg model years noted in the product listing.
• Not universal—verify engine year/model against the product DESCRIPTION on the listing.

How will replacing these parts affect engine performance?

Worn injector seals and caps can allow fuel or oil to leak around the injector bore, which leads to odors, rough idle, and reduced fuel control. Installing fresh seals and retaining caps helps re-establish a tight injector-to-head interface and can reduce those symptoms while improving combustion consistency.

• Reduces fuel smell inside and around the vehicle by stopping leaks at the injector top.
• Can improve idle smoothness by removing air or fuel seepage at the injector interface.
• Prevents oil dilution and potential engine damage linked to leaking injectors when seals fail.

What parts are included and what do they each do?

The kit bundles the typical upper and lower O-rings, upper seals, and pintle caps needed for a full injector-top service on six cylinders. Each component is sized to replace the OEM items so you get a complete set to swap all injector openings at once.

• 6 upper O-rings to reseal the injector stem to the fuel rail/head interface.
• 6 upper seals that create the primary leak barrier at the injector bore.
• 6 upper and 6 lower retaining pintle caps to protect the injector tip and hold seals in place.
• 6 injector caps that finish the assembly and help center the injector.

Can I install this kit myself, or should a pro handle it?

Installation requires mechanical skill, correct tools, and safe handling of pressurized fuel components. The kit does not include a manual; if you’re not confident in fuel-system service, a qualified technician or garage is recommended to avoid improper installation or injury.

• Professional installation advised for most users; videos and guides are available online.
• Ensure fuel system is depressurized and battery is disconnected before work.
• Use correct lubricant/assembly practice for O-rings and ensure clean injector bores.

Who is this for: This X AUTOHAUX kit is for owners or technicians servicing Audi A4/A5/A6/A8/Q7 and compatible VW Touareg vehicles who need a complete six-cylinder injector-top repair set. It suits those diagnosing fuel smells, rough idle, or suspected injector seal failure and who want an OEM-replacement parts group to restore sealing without buying individual pieces. Always confirm part-number compatibility with your vehicle’s engine code and model year before ordering.
