Injector Inserts- Audi 5-Cylinder 20V (Set of 5)

About this kit: This is a set of 5 upgraded injector inserts, designed to perfectly match the original OEM specifications but built to last a lifetime. Nothing fancy here, just heavy-duty engineering. They are so durable that your engine will probably give up before they do! 

Material: CNC-machined from high-grade stainless steel

Outer thread: M22x1.5

Why upgrade? If you are on this page, you likely already know why these are essential. Over time, the factory-installed plastic inserts become brittle and start to crack. If you're unlucky, pieces of broken plastic can fall directly into your intake manifold—which is a nightmare for your engine.

By upgrading to these stainless steel inserts, you permanently eliminate this weak point and get peace of mind.

Note: For proper installation, Loctite 542 might be necessary.
