 This is a set of three replacement OFNA manifold springs, intended for use with the OFNA Hyper 9 Pro Manifold. These are the small short springs that attach the tuned pipe to the
manifold. These springs will generally get weaker over time due to the
amount of heat generated by the engine, so it is a good idea to replace
these springs if they become loose (you should also replace the
manifold gasket at the same time). If your tuned pipe is leaking around
the manifold/pipe connection, it will make the engine behave
erratically.
