Advance auto Beck/ Arnley P/N 158-0431. For the kit, 9.99

 

thanks guys thats a hard part to find

 

thanks for posting that, reminded me that I need all those O rings for when I swap in the 1.8 injectors LOL

 

some day it'd be great to compile all the part number threads for obscure parts that everyone needs cheap and local sources that stock them.

 

They're cheapest at the dealer I've found, I had to special order some from napa and they were like 11 bucker per injector, whereas the dealer has them for half that
