Bosch Injector length comparsion:

An illustration to compare the different sizes of injectors. The size is measured between the o-rings if you want to check the length of your existing injector.

Some injectors (not this one) have an extension (xT) from the lower o-ring measuring 24mm. This can be inserted to the intake manifold or rebuilt with the help of a lower adapter to get the standard 11mm protrusion.

Flow Matching:

These injectors are delivered directly with factory tolerances unless you choose to match those with much less tolerances than factory. Choosing to match the injectors with our top of line machines before delivery will get the matching much more correct, we always recommend if you do that. Or you can choose to drive them unmatched with greater tolerances, match the injectors themselves or compensate for the diffusers to divert slightly in flow when mapping the ECU system. How much they differ from the factory always vary.

When you choose to match the injectors, this is done with our top equipment! Documentation and certificates from us are included with the injectors when you choose this option.
