Upgrade your Nissan SR20 & CA18 with the GRP Engineering Titanium Exhaust Manifold Stud Kit. Factory steel hardware is prone to rusting, seizing, and breaking in the aluminum head. Our titanium studs are corrosion-resistant, much lighter, and designed for extreme heat, ensuring easy removal every time.
| Stud Length Option | Length (Total) | Nut Type | For Wrench Access |
| Short | 42mm | 6-Point Nut | Tight Clearance |
| Full | 52mm | 12-Point Nut | Standard Manifolds / Easy Clearance |
| Half-Half Combo | Half 42mm, Half 52mm | Mixed 6- & 12-Point | Allows for the shorter studs to be used under where clearance is crucial |
Other Information:
For optimal fitment and secure installation, please clean the threads using an M10x1.25 Bottoming Tap before installing the studs. A suitable tap can be supplied via the dropdown option.
