So my 2004.5 truck has 220,000 miles on her and the injectors are going bad so I am asking if the rebuilds are ok or to go with new ones from the dealer. To have a performance shop replace with remanf. it will cost me about $3000. and to have the dealer put in new ones they said $3600. Is there any differance in quality. The performance shop is telling me that he would only do the work if they install new extensions as well. The dealer tells me they do not need to be replaced. Any help would be great. Thanks
