1. A system, comprising: a first pre-combustion chamber configured to removably couple to a cylinder head of an engine, wherein the first pre-combustion chamber comprises at least one of: a first cooling jacket disposed about a first inner body having a first chamber, wherein the first cooling jacket is removably coupled to the first inner body via a removable coupling; and a first frustoconical exterior extending a first distance of at least half of a first axial length of the first pre-combustion chamber from a first annular tip at a first end toward an opposite second end, wherein the first frustoconical exterior has only one angle relative to a first axis of the first pre-combustion chamber. 2. The system of claim 1, wherein the first pre-combustion chamber comprises the first cooling jacket disposed about the first inner body having the first chamber, wherein the first cooling jacket is removably coupled to the first inner body with the removable coupling. 3. The system of claim 2, wherein the removable coupling comprises threads. 4. The system of claim 2, wherein the removable coupling comprises one or more fasteners. 5. The system of claim 2, wherein the removable coupling comprises a clamp. 6. The system of claim 5, wherein the clamp is disposed adjacent axial ends of both the first cooling jacket and the first inner body. 7. The system of claim 5, wherein the clamp comprises an axial extension extending partially axially into the first cooling jacket. 8. The system of claim 7, comprising a seal disposed between the axial extension of the clamp and the first cooling jacket. 9. The system of claim 2, wherein the first inner body comprises an annular exterior portion, the first cooling jacket comprises an annular interior portion, and the annular exterior portion is removably coupled with the annular interior portion via the removable coupling at a first interface. 10. The system of claim 9, comprising a first annular seal disposed between the annular exterior portion and the annular interior portion at the first interface, wherein the first interface is disposed at a first end portion of the first pre-combustion chamber adjacent the first annular tip of the first pre-combustion chamber. 11. The system of claim 2, comprising a coolant passage disposed between the first cooling jacket and the first inner body, wherein the coolant passage is disposed between a first end portion and an opposite second end portion of the first pre-combustion chamber, the first end portion comprises a first seal, and the second end portion comprises a second seal. 12. The system of claim 1, comprising the first frustoconical exterior extending the first distance of at least half of the first axial length of the first pre-combustion chamber from the first annular tip at the first end toward the opposite second end, wherein the first frustoconical exterior has only the one angle relative to the first axis of the first pre-combustion chamber. 13. The system of claim 12, wherein the first frustoconical exterior having only the one angle extends from the first annular tip at the first end to a flange at the opposite second end. 14. The system of claim 12, wherein the first frustoconical exterior having only the one angle extends along an entire length of the first chamber. 15. The system of claim 12, comprising the cylinder head having a first receptacle, wherein the first pre-combustion chamber is removably coupled to the first receptacle, and the first receptacle comprises a first mating frustoconical portion. 16. The system of claim 15, comprising a second pre-combustion chamber removably coupled to a second receptacle in the cylinder head, the second receptacle comprises a second mating frustoconical portion, the second pre-combustion chamber comprises a second frustoconical exterior extending a second distance of at least half of a second axial length of the second pre-combustion chamber from a second annular tip at a third end toward an opposite fourth end, and the second frustoconical exterior has only one angle relative to a second axis of the second pre-combustion chamber. 17. The system of claim 1, comprising the cylinder head having the first pre-combustion chamber. 18. The system of claim 17, comprising the engine having the cylinder head with the first pre-combustion chamber. 19. The system of claim 1, wherein the first pre-combustion chamber comprises: the first cooling jacket disposed about the first inner body having the first chamber, wherein the first cooling jacket is removably coupled to the first inner body via the removable coupling; andthe first frustoconical exterior extending the first distance of at least half of the first axial length of the first pre-combustion chamber from the first annular tip at the first end toward the opposite second end, wherein the first frustoconical exterior has only the one angle relative to the first axis of the first pre-combustion chamber.
