Denso Hairpin High-Output 1999-2004 Mustang GT


Rated at 185A peak these units offer greater idle performance (up to 140A) with a higher efficiency than any replacement 3G/4G/6G based unit.

When compared to our 1st Generation J2Fab-200A 6G this unit has an idle output 27% greater, will reach peak output 50% sooner, and will hold its peak output longer making it superior to the old J2Fab-200A and any other 3G/4G/6G center mount unit in every practical way.

Ideal for cars with high draw from fuel system, A2W trunk mounted pump, H/E fans, stereo, or OEM 2Valves just looking for an upgrade/replacement with much greater longevity and resistance to overheating!

Customers running a combination of fuel system, Stewart EMP, electric WP, H/E fans and more, please consider upgrading to the 270A Extreme version for your application.

  • 100% new components and direct bolt in case.
  • Custom rotor/stator to decrease air gap to improve idle output.
  • Balanced rotor and 0 run-out slip rings to improve unit life and eliminate battery light flicker.
  • Heavy duty 12 diode twin rectifier plates
  • Improved air flow to ensure long service life in severe conditions
  • NTN premium and NSK USA bearings.

This unit will ship with a similar to OEM sized pulley that is suitable for stock and over-driven balancers. No RPM limit.
