This article applies to the Acura TSX (all years K24 engine models).

The air filter is the gate between the outside world and the inside of the Acura TSX's engine. Over time, the engine air filter gets dirty and clogged, which starts restricting the air going into the engine, thus decreasing its performance. When the engine feels restriction, it works harder to maintain normal performance, which results in burning more fuel. Replacing the engine air filter is one of the most basic pieces of maintenance, which means you should replace it at least once ever two years if you really want the full engine performance. Read on to learn how to replace the engine air filter in the Acura TSX yourself.

Step 2 – Remove air filter

Don't yank the lid out, since it's still connected to the intake tube; instead, just pull it up a little bit, then pull the air filter out.
