Product Description

The GSC 3128-8 intake valve guide set replaces the factory guides on the SR20DET with a stopper-style design engineered for precise, consistent installation depth - a key factor in maintaining accurate valvetrain geometry across 240SX, Silvia, and 200SX applications. Precision manufacturing to exact specifications reduces the risk of valve wobble and leakage, both of which can lead to reduced engine efficiency or long-term damage.

By maintaining proper valve alignment, this guide set supports better combustion, improved power output, and smoother overall engine operation. For SR20DET owners performing a head rebuild or valvetrain refresh, this set installs with standard tools and pairs naturally with GSC's matching valves, springs, and exhaust guides for a complete, application-specific upgrade over factory guide material.
