Product Description

The Brian Crower BC3928 Intake Valve Guides are engineered for the RB26DETT engine, offering premium intake side guide support that enhances durability and reliability under high-stress conditions. Crafted from manganese silicon aluminum bronze, these guides combine strength, heat resistance, and great wear properties - ideal for high RPM or forced-induction setups.

With a 6.0 mm stem diameter and a full head set (12 pieces), this replacement set is suited for all intake valves in the RB26DETT head. These guides pair directly with Brian Crower stainless steel intake valves, restoring proper valve seal and reducing wear in the intake port. Proper installation requires cylinder head removal and guide pressing with care to lubrication and tolerances.

Fitment is confirmed for model years 1990 through 2002 with the RB26DETT engine. 2025 coverage unconfirmed beyond those years. Match with exhaust valve guides and other valvetrain components for a complete, long-term performance rebuild.
