This 14mm diameter injector adaptor enables ‘short’ injectors (45 to 50mm) to be converted for use on assemblies requiring a length such as 60mm.

Made from red anodised CNC machined aluminium, it incorporates a crimped filter and is supplied with the injector gasket.

In certain configurations (swap, engine preparation, rail conversion), it is common to have a problem with injector length:

➡️ your manifold requires a length of 60mm
but your injectors are only 45 to 50mm long.

Result :

• poor seating in the injector well
• leaky seals
• poor alignment and impossible assembly

✅ This adapter allows you to extend and adapt your injectors for a clean and reliable fit.

It is designed for 14mm diameter injectors ( Siemens / Bosch EV1 type), particularly those used on performance assemblies (Siemens DEKA, EV1…).

✅ Integrated filter
An injector filter is crimped inside the inlet, effectively protecting the injector against :

• micro-particles
• fuel impurities
• circuit pollution

➡️ Ideal solution for serious, long-lasting, “pro” installation on a performance rail.
