If you have leaking or carboned injector nozzles in your Chevy Duramax LLY, SPRINT 1385 nozzles will directly replace them with high quality nozzles from Fratelli Bosio.

The unrivaled flow tolerance of +/-2% will make your truck run better than when it was new.

Avoid core charges and uncertain exchange parts by doing it yourself on your own injectors. You keep your old nozzles, no core required. Fratelli Bosio, SRL
