Billet Injector Cups (1.8T small port)

After dealing with cracked or leaky injector cups, we decided it was time we do something about it. Machined from 6061 aluminum and (most models) anodized for durability and corrosion resistance. Installation tool, brush, new o-rings and such are included for convenience. Our Billet 1.8T Fuel Injector Cups are a direct replacement for stock and are priced per set of four. Shipping is free within USA (including AK & HI). Contact us about export details.

1.8T injector bungs

Installation kit consists of the following elements:

  • 17/20mm machined hex to remove stock cups and install the replacements
  • Stainless steel wire brush to remove OEM thread sealant from the intake manifold threads
  • Loctite thread sealant to replace original sealant and ensure a leak free fitment

Note: Installation should be done with the intake manifold out of the car. This is to prevent sealant and whatever other grime is on or around your stock injector cups from dropping into and contaminating the engine. Upon removal of the stock injector cups the intake manifold threads will need to be cleaned prior to installation. We strongly suggest adding an installation kit if you don't have the necessary items to remove, clean and reseal the injector cups properly.
