Got a Nissan or Infiniti from '89 to '04 that's running rough?

A bad fuel pressure regulator could be the culprit.

This Herko PR4154 is a brand new, direct replacement unit that runs at 3.0 bar.

It's a solid aftermarket piece that crosses over with a ton of OEM numbers like 22670-74T00, 22670-40F01, 19164585, and many more from brands like AC Delco, Delphi, and Denso.

It comes in its original Herko box and is ready to bolt on.

Plus, it comes with a 1-year replacement warranty, so you're covered.

Just a heads up for California folks: there's a Prop 65 warning for lead, but otherwise, it's good to go.

Get that fuel pressure back in spec!
