Our M8-1.25 stud kits are ideal for replacing corroded OEM inlet or exhaust manifold bolts. Our studs are made of high-quality Grade 5 titanium alloy, ensuring their durability and longevity. Each kit has a 3mm hex key tip, allowing easy installation with an Allen Key/Wrench without damaging the threads.

Not only are our stud kits visually appealing, but they are also lightweight and will never corrode. They are compatible with combined gasket and manifold depths up to 20mm, making them versatile for various applications.

Using factory exhaust manifold bolts and studs, especially when paired with an aftermarket intake manifold or header/turbo system, can lead to stripped or broken bolts and inadequate clamping force, ultimately resulting in leaks.

Grade 5 Titanium fasteners can replace Grade 8.8 steel fasteners, offering an excellent strength-to-weight ratio and weight savings of approximately 45% compared to equivalent steel bolts. Furthermore, Titanium provides superior corrosion resistance to a wide range of harsh chemicals, leading to a longer service life than standard BZP steel bolts.

We've taken the time to test these on our favourite Honda engines to ensure we have intake and exhaust stud kits for the most used applications. 

In summary, our M8-1.25 stud kits are a reliable and good-looking option for those looking to take their build to the next level.
