After a long journey of curiosity to see if the 2013 Toyota camry 3.5L V6 K&N Short ram intake would fit in the lexus ES 350 or not, I have a confirmation. After I ordered the intake for my ES, and installed it, I can confirm that it does fit properly, and I did not record any check engine lights or any warning lights. The intake fits and works fully functionally and properly. It sounds very nice. Not too loud. In fact, you can only hear it if you press down on the gas a little more than half way. Otherwise, it doesn't make not a sound. I did like having the intake, but unfortunately I had to uninstall it due to the fact I accidentally over-tightened the clamps on the k&n Intake tube, which caused the k&n tube to bend in, making the sound just a tad weird. The sound is nice and deep. Sounds like, I don't know, something different, a sweet sexy beast, if you know what that sounds like. Anyways, I reconnect you try this figment if you want a little more thrill out of the ES. Chow!
