    4g64 exhaust manifold bolts?

    My daily galant is getting headers installed but I need to replace the bolts or studs that go from the head to the exhaust manifold. Anyone know a part number or what I should look up? I cant find anything on oemmitsubishiparts, rockauto, ebay, or a quick google search.

    I want to assume I can use these, but mine are soo rusted I don't know if the ends are bigger or not like an evo head lol.

    I believe those will work. Iirc the nuts are 12mm and the two end nuts are 14mm

    Just get some studs with the same thread pitch from ACE. They will either be in the bolts section or automotive section. that where I got my extended studs for the manifold.

    I'd rather have the knowledge and ability to do it than the money to buy it already done.

    Oh good lord.

    Just order a OEM Mitsubishi stud, washer, nut kit.
    That flange sees a lot of heat cycling. You want to make sure you use bolts that are designed for this purpose.
    I've never been a fan of stainless steel studs. They WILL snap off, the bolts WILL back off. It only took a week for my turbo manifold to snap them, this is after following property torque procedure and rechecking after one heat cycle.

    This is what you want.
