K&n Air Filter For Is350... Is It Good?

[REVO350]

According to Lexus IS350 maintenance manual, the air filter needs to be replace at 15K miles. So, i'm just wondering if anyone here has already use K&N air filter and what your opinions are? Thx in advanced.

You could probably go a little longer.. 15,000 just to get you in more often and make more money if you ask me. I don't think you'll realize a difference by switching to a K&N filter, though it might be a little less restrictive than an oem air filter. The only way you would notice a difference is if you were to install a Cold Air Intake of some sort. An upside to the K&N, though, is they can be "recharged," or cleaned, for less than buying a new filter, so in the long run could actually save you money. Also these are simple to change yourself, so don't pay the dealership to do it.
