I don't think they thought that through at all. Seems to me like they just had access to the 1.8 but not the 1.4. They probably decided to do a test run of 1.8s and when they didn't sell well they put the 1.4 development on the back burner so to speak and went after more popular cars instead.I just don't understand how they thought they were gonna make money with making a 1.8 filter over a 1.4
I'm just guessing though, someone at AEM may have a different take on it, especially if it's one of those canned official statements.
