It's an old thread, but for anyone interested. Denso do make aftermarket coils but for Toyota they are OEM, so quality is good. As for using ZRE152 in place of the ZZE122, that is not possible as they are very different coils (see attached images), the one on the left is ZZE122, the right is ZRE152.
Hi Toyota owners and enthusiasts, As a new member to this forum and an Australian branded ignition coil supplier, I want to make a quick introduction to ask that if you have any ignition coil related questions, please feel free to message direct or post a thread. I will try my best to answer any related questions.
