Hi guys,
While web surfing I came across an Australian web site advertising HEUI injectors for our 4JX1 Jackaroos. Current price is $1,452 for a set of 4 or $577.50 for one. Price can be even less using their 'core exchange' service. Note that these are reconditioned, not new, but could be a good choice for those looking to replace faulty injectors. They come with a 12 month, 20,000km warranty.
For more information go to http://www.dieselcenter.com.au/diesel-fuel-injectors/?subcats=Y&features_hash=V1900.
I have no affiliation with this web site or Diesel Centre Australia.
Cheers,
JackDriver
