Our 258° cams are perfect for 3S GTE engines with either OEM turbo or upgraded turbo sizing ranging from 48-54mm. They work well for both street and turbo applications, while still maintaining good drivability. You can expect a significant improvement in mid-range power when compared to OEM cams. Plus, it works great with E85.

• For the best performance, it is recommended to also use the KVS109-3S valve spring upgrade, as suggested by Kelford Cams.
