I have two excelerator EQ2 coils (5" and 16.5") for Explorer/Quattro/Safari/Etrac. The 5" coil is in like new condition and the 16.5 shows signs of wear but works perfectly. The larger coil has a cover the smaller one does not. I bought them both from a forum member only a few months ago and haven't used either one since I have two others. $106 for both shipped.
