Since both our cars are over 100K miles and I just had 1 injector go bad we probably have ot start thinking about replacing them all. Buying hem from the dealer is out of the question at 135$ each. The second option is the typical Bosch replacement at O'Rieleys but those are 65$ each. SCP and summit has 24# inctors forlike 250$ for a set. Is this a viable alternative?
