So I went and bought some replacement injectors as shown above. Unfortunately, this is the response I received from Ferrari when I took them there to be checked:
We have checked those injectors you have supplied us. Knee jerk reaction – they’re different, they have pink housings opposed to the standard orange. Checking the bosch numbers on them and they are different there again. These ones are 0280 150 449 which I don’t believe are compatible?
Checked anyway to see differences:
– O ring height/ position is different between OEM and supplied injectors
– Rated impedance is different, 15.5 ohm for OEM vs 16.4 ohm on supplied injectors
– Injector nozzle is different – OEM is pintle type, supplied are multi point
– Flow testing differently as well, OEM are around 82-83mm over 15 seconds, vs only 75-76ml on supplied ones.
They may physically fit, however given the differences, I don’t believe it would be an appropriate replacement.
The bosch numbers on the original injectors is 0280 155 013
According to a quick look on Internet:
- 2.7 0280 155 013 15.4 Ohm Single Spray; 0 280 155 003 appears to be identical to 013, all parameters are same and both have 291 ml/min static flow at 3 Bar
- 2.7 0280 155 869 14.4 Ohm Dual Spray, slightly higher flow than the above two, 305 ml/min static flow at 3 Bar (I do not know the VIN/year of change)
- 5.2 0280 150 449 15.9 Ohm Dual Spray, 267 ml/min static flow at 3 Bar possible alternative
- 5.2 0280 150 786 15.9 Ohm Single Spray, 260 ml/min static flow at 3 Bar (but it has single spray pattern)
So it appears the ones I found are 0280 150 449 which seem to be for a 5.2 Motronic engine not a 2.7 as I need. Seems I need any of these:
0280 155 013
0280 155 003
0280 155 869
What a challenge this is proving to be.
Love the F355
