I have a set of six Injector Dynamics fuel injectors for sale. Part Number 7188.8.131.52.6. They are as new condition and were purchased about 2 years ago, but never installed. They are a direct bolt in replacement for Bosch injectors used on 84 thru 98 Porsche FI engines. $400.00 for the set. Thank you, Rich 805-368-5718.
