The Tomei SR Series valve spring seat is a precision component engineered for NISSAN SR20DE and SR20DET engines. This 0.3mm thick seat is part of an 8-piece set, designed to ensure uniform specifications crucial for high-performance engine builds. These valve spring seats are a critical part of any engine build where precise valve train geometry and consistency are paramount.

The SR Series is specifically tailored for popular Nissan engines. This particular set is compatible with the NISSAN 13 SILVIA, NISSAN 14 SILVIA, NISSAN 15 SILVIA, and NISSAN 180SX models. As with many performance-oriented engine components, professional installation by a trained mechanic utilizing specialized tools is recommended to ensure proper fitment and function.
