These are Jet-Hot coated headers originally purchased for an M54 engine. They are coated with the toughest coating available. This is the recommended coating when using forced induction due to the heat generated. They can also be used in a non supercharged or turbo car. Either way these headers can free up some HORSEPOWER. They are brand NEW and NEVER USED.
The M54 egine came in the:
330, e46 boby
3.0 Z4, E85 body
530, E39 body
Headers may fit 2.8, 2.5, 328, 325, 528, 525 (To be honest I'm not sure of fitment) My X bought these for Christmas and had them coated. She was a top shelf kinda gal. I beleive they are SuperSprint, but cannot guarantee this since we have split up.
If they are SS:
Jet-Hot coating $295
Headers $1200
$800 takes them before they goto E-bay
