Tomei Valve Springs
Tomei

In terms of transferring the exact movement of the camshaft, the highest quality valve spring is required to the high RPM, high powered tuned engines. We developed our products with the most careful choice of the material, coating and the other technologies. Then we repeated severe tests to our pre-production in order to give the best quality that is performed in any situations.

Features

  • 163022 - Valve Spring Set for RB25DET for Solid Camshaft  Note: Intake valve springs of RB25DET are short, so they are not used on the High lift camshaft. So only the intake uses the offset retainer and longer valve springs set on the cylinder head for getting the spring stroke.
