They are perfect for those who tow heavy loads and want more responsive power.

very cool that it comes with the 3k or 4k option (using 3 or 4 springs changes it) and wow best investment ever. Really woke the top end up but on a stock turbo I don't recommend these without an egt gauge because you can really do some damage at the temperatures you can reach after the install
