Brand new oem bosch injectors for an LML 2011 through 2016. $2,600 for the complete set of (8) shipped anywhere in the contiguous U.S. NO cores are required.

Looking for help/instructions on replacing fuel injector/s for a 2017 5.3L Silverado. Truck has 80K miles on it and a #5 misfire. Dealer ran a diagnostics and said the injector needs to be replaced. I found a couple pictures on the forum of the fuel injectors but very little information on steps to replace them. The only videos I could find online were for older models with a different injector diagram. Talking to the dealer they quoted me $770 to replace a single injector, gaskets and piping associated with the job. 4 hours or labor and $240 in parts. Are there any good instructions or videos out there on replacing fuel injectors on a 2017 Silverado? I've never done a job like this but consider myself mechanically include, is this an easy enough job or should I leave this to the dealer to do? I know they say if your replacing a single injector you might as well replace all 4 on one bank but is that really necessary, $110 a piece and if the other 3 are fine why replace them? The dealer said the piping and gaskets must be replaced even for a single injector replacement job. Is this all necessary? I've never had another vehicle with injector problems so this will be a first. Parts quoted- 12687650 (1) injector 12626354 (8) gaskets 12677002 (1) pipe 12677004 (1) pipe Any help, links to instruction/diagrams or videos would be awesome! I enjoy working on these projects rather than paying someone else to do the work since you learn something every time. I also want it done right. Thanks all in advance!
