CAT 3406E "58" Injectors

Step up your CAT game with a set of CAT 0R0958 injectors, also known as “58s” in the Caterpillar community. Originally found in 550HP 3406E engines, these injectors are a favorite for lightly modified 3406E and C15 builds needing a bump in fueling without going overboard. Momentum Worx sells these as a matched set of 6 for a clean, balanced install.

The 58s flow approximately 10% more fuel than 57s, making them perfect for trucks with mild tuning, upgraded turbos, or anyone looking to wake up their CAT without compromising driveability or reliability. This is a performance upgrade straight from the Caterpillar playbook.
