The use of factory manifold bolts and studs, especially with an aftermarket header/turbo/intake manifold can result in stripped or broken bolts and inadequate clamping force, resulting in leaks.
SpeedFactory Titanium Stud Kits are made of high quality Ti 6Al-4V and incorporate a hex key tip that allows them to be easily installed using an Allen wrench. Titanium 12-point nuts and washers are included.
