Yes, for now. I can always ask when I'm looking at parts. I've been seeing this for a long time and wondered if anybody knew why.

Was the 09 using 18mm wide band O2 sensors or 18mm narrow band sensors?

because it complies with emissions regs...

in general to comply with CARB regs you can replace a motor with a same type block (lower end)- so in a camaro that came with a 307, you can;t easily put in a big block 396 without a cert process- but you can put in a 302, 350 or a 400 small block.

so the same may carry onto the 120ST ( street) as opposed to the 120R ( Race)- the 120ST has been certified to comply- and carb certs are available online

with all things performance though the dealer is not your best stop for power or cost- it's just now what they do.

most of us violate the emissions regs with a stage 1, using off road, closed course parts.
luckily testing isn;t done anywhere- but it could always come in.
we had testing in a couple of counties in AZ for many years- I would have to really play some tricks to get my BMW to pass.
