The air filter stops the engine from sucking in physical pollutants like dust or leaves, which are abrasive to the engine components. When the filter is dirty, air doesn't flow as freely, resulting in less power and a rough idle. The air filter should be examined at around 6,000 miles. If you live in a dusty area, it’s advisable to check the filter more frequently. Replacing it depends on its condition, but the recommended interval is when your Lexus IS has clocked 10,000 miles.

This moderately difficult job takes 15 to 30 minutes and costs from $10 to $70 dollars, depending on the air filter you purchase. You can expect to pay an extra $50 dollars or so for labor at a repair shop.

For this job you’ll need a Phillips screwdriver and a new air filter.

Step One - Unscrew the air intake assembly cover

After opening the car hood, look to the passenger side where the plastic covering for the air intake assembly sits. There are three push-pins and a one flat head screw holding the plastic cover in. Press the center of the pins in to pop them out. Remove the cover to get access to the air intake assembly.

Step Two - Unclip the air box

There are four metal clips securing the air filter cover to the assembly. Squeeze the clips, and pull them from the cover.

Be attentive when pulling the clips; they can fall off and get lost under the engine.

Step Three - Replace the air filter

Remove the worn out filter and insert the new one. Then, replace every component earlier removed in the reverse manner.
