Product Description

New Power Transistor Kit. PTUs are known for going bad causing all sorts of poor running conditions or even shutting down completely. Connectors on the original harness aren't sealed, so really bad corrosion, at this point in the ignition circuit, is really common and often causes the same running issues, or worse not running at all. Sometimes the connections can simply be cleaned from the connector, but often problems will persist because the corrosion has worked its way into the harness.

This OEM Power Transistor Kit is a perfect replacement for any PTU that has gone bad or is on its way to failure. 

Includes:

  • (2) Plastic Fastener
  • (4) Short Bolts
  • (2) Long Bolts
  • (1) PTU Unit Bracket
  • (1) PTU Unit
  • (1) PTU Harness
  • (1) PTU Harness Bracket

Fits:

  • 1990-1996 300ZX (Z32)

My vehicle had no hesitation symptoms. I increased thew boost with an electronic boost controller. This raised the heat in my engine compartment. I got the Z1 wire harness which fit perfectly, and that made the relocation of the PTU a breeze. I had intermittent total power cut hesitation under load. It was fine at idle. Once I ruled out fuel pressure, I replaced this. Totally fixed the issue. Get this PTU before it goes way up in price! Some say the PTU either works or does not work., This part was failing intermittently under load! Replace it!
