disappointed in the aftermarket

[cali yaris]

^ yep. Like I said it was an observation and not a criticism. It's also an explanation why where aren't more aftermarket parts that require more extensive R&D.

Making an intake manifold that (1) makes power and (2) doesn't cause CELs is not just throwing some piping together, for example.

I'm grateful for the business that is out there, it keeps me in the scene, at least partly.

Let's take a look at the Honda aftermarket scene in the year 1980 (about the same age as the Yaris is now, 5 years into sales). I was there, and there wasn't much available. This is no different.
