The housing you receive will mimic the fit and function of the unit that is currently installed.\n \u003c\/li\u003e\n \u003cli\u003e\n  This unit will mount in the exact same location using the same threaded ports as your original. This unit\n  \u003cu\u003e\n   WILL NOT\n  \u003c\/u\u003e\n  come with replacement mounting hardware. However, you will be able to reuse your current hardware without issue.\n \u003c\/li\u003e\n \u003cli\u003e\n  This part is made with OEM Equivalent Materials, Design and Manufacturing Methods.\n \u003c\/li\u003e\n \u003cli\u003e\n  Tubing used is CuNi (Copper Nickel) which is the new industry standard. This material is a significant improvement over the standard copper tubes that are on all original units. The addition of nickel to copper significantly enhances the ability to withstand corrosive environments. It forms a more protective surface film. This will help to reduce pitting, crevice corrosion, and stress corrosion cracking.\n \u003c\/li\u003e\n \u003cli\u003e\n  The Fin count is 25FPI\n  \u003cstrong\u003e\n  \u003c\/strong\u003e\n  as with the OEM\n \u003c\/li\u003e\n \u003cli\u003e\n  Mr Cools headers are made with extruded billet brass\n \u003c\/li\u003e\n \u003cli\u003e\n  \u003cbr\u003e\n \u003c\/li\u003e\n \u003cli\u003e\n  This is better brass material than from other parts of the world where only one substandard brass is allowed for export.\n \u003c\/li\u003e\n \u003cli\u003e\n  Or they use machined cast headers which have a lower density likely leading to a shorter product life.\n \u003c\/li\u003e\n \u003cli\u003e\n  Using lubricant makes it easier to install the part and then remove it when doing your regular maintenance.\n \u003c\/li\u003e\n \u003cli\u003e\n  Smaller which matches the OEM offering plus a larger cross section which may compensate for a worn housing as your system ages.\n \u003c\/li\u003e\n \u003cli\u003e\n  Although this is disregarded by some YouTube installers these stabilizers are quite important.
