barneybrendan Posted January 17, 2010 Author Share Posted January 17, 2010 ive got some 550 low imps do i need some sort of resistor to fit them. Quote Link to comment Share on other sites More sharing options...
steve spedd Posted January 17, 2010 Share Posted January 17, 2010 are they from the mkiii? im pretty sure you will need one. Quote Link to comment Share on other sites More sharing options...
barneybrendan Posted January 17, 2010 Author Share Posted January 17, 2010 are they from the mkiii? im pretty sure you will need one. not sure i bought them from here fitted in mk4 na rail cheap.they are denso and after some research are low imp part number 195500-1370 the connector has the nib in the middle and are purple.

Homer Posted January 17, 2010 Share Posted January 17, 2010 They could be either, though the UK spec injectors are lilac in colour and have a low impedance. Easiest way to check is to put a multimeter across the two terminals on an injector and meassure the resistance. Can't recall the exact values, but 12-15 ohms should be high impedance, 1-2 low.

Homer Posted January 17, 2010 Share Posted January 17, 2010 will double check that.is it much to fit resistor if needed. About £50-60 IIRC, plus the costs of the wires and connectors, but they are a PITA to wire in as you have to splice into the main engine loom.

barneybrendan Posted February 3, 2010 Author Share Posted February 3, 2010 just checked them they are 2.1 ohmz.does that mean low imp then and i need a resistor.might see if anybody has high imp ones they want to swap for them. Quote Link to comment Share on other sites More sharing options...
