Product Description

The GSC Power-Division 3045-12 Exhaust Valve Guide Set is engineered for the **Nissan VR38DETT 3.8 L twin-turbo V6 engine** used in the R35 GT-R platform. Made from precision CNC-machined manganese bronze, these **standard-size guides** replace the original exhaust side guides with superior heat dissipation and wear resistance - key points for turbocharged high-performance engines where exhaust temperatures and stress can be elevated.

This set of 12 exhaust guides is a direct OEM-style replacement that maintains tight valve stem alignment through high RPM and boost conditions, helping reduce premature wear and improving durability during engine rebuilds or head service. Professional installation with correct pressing tools is recommended to achieve proper seating and performance. The guides are suitable for both stock and modified GT-Rs running high-boost or track applications.
