I was wondering if anyone knew about mazda using a couple different colored tops for the fuel injectors with the same part #. anyway here is the situation and i was hoping that someone could help me resolve it. I got some 550cc low impedence injectors on ebay (he had a perfect rating with over 1200 feedback rating and delt with mazda's but i was wondering if he was wrong) he swore up and down all were low impedence when i questioned him anyway two were brown or tan topped #1995500-1370 and two were the same part number with a redish/purpleish top. both have a notch in the center and fit into the same harness connector. are the both 550's or are two of the 460's? anyway any help would be appreciated.

1370 are turbo 550

1350 are non turbo 460's

Screw colors for identification. Numbers embossed on the side count.
