I agree with the above statement for two reasons. First is that new injectors could be poorer than what you have already from reports. Plus yours may check just fine or only one needs attention for example. I believe there is a gentleman with good feedback on ebay with a checked out set for a non turbo engine. On now for 135.00. Get a price for a check locally and if close dollar wise you could grab those. I am not the guy selling them by the way. Really not even 135.00 as he throws in a new filter and the braided hose to connect the returns of the injectors and another thing or two like new heat shields.
