Re:
There isn't any CARB legal CAI for the V8's. The TRD CAI is only for the V6, and it won't fit on the V8. If the CAI is 03-08, it *should* fit the 09. Nothing was changed in that department for the final year. Like, my Borla system says v6, v8 03-08, and I asked them about the 2009, and they confirmed it will fit the 2009 as well. Some products out there will fit both v6's and v8's but not all products are manufactured to do so. It sucks for me I have to get my vehicle smog'd for base stickers frequently so I'm constantly changing out my Volant CAI for the stock airbox.
Oh and last but not least you can still get a TRD exhaust system but they stopped making the CAI. You'll have to buy one used or hopefully overstocked.
