These studs are available for all 12a 13B and 20b engines including the MSP-13B Rx-8 engine, 13REW, 13RE, 13B, & 13BT. This stud kit is a more linear, and precise medium of torqueing the engine compared to stock tension bolts. Torqueing the stock bolts creates friction at both the threads, and head of the bolt.
Made out of high tensile steel.
These are designed to be a direct drop in stud to replace your factory ones but designed for high power/ boost engines.
Come complete with 10mm studs, grade 10 nuts, o-rings and washers.
Install tool available.
