This chromoly black oxide ARP bolt kit is for the Evo 4-9 with a FP cast manifold to replace the bolts and washers that secure your manifold to the turbo. Includes a set of four black ARP bolts with washers. We definitely suggest a touch of anti-seize on your bolt threads before install.
May Require Grinding – Read Before Purchase!
When we initially test fit these ARP bolts on the FP cast manifold, they fit perfect, no issues whatsoever. The more kits we sold, the more feedback we got that the ARP bolt heads weren’t clearing the manifold. It seems some of the manifold castings are slightly different. Just be aware, there is a possibility you may have to grind the casting down a touch to clear the bolt head. So if you have a ceramic coated FP manifold… do you want to take that chance? So far, the STM OEM Bolt Kit has had no fitment issues whatsoever with the two piece stud/nut combination on the shorter ends.
