Replace Engine Air Filter for Better Performance

The Problem

Dealer charges $40-60. Your engine breathes through a clogged, dirty filter that restricts airflow.

The Hack

Buy an engine air filter for your car on Amazon ($8-15). Open the airbox (usually black box near engine with clips). Remove old filter, drop in new one, close clips. No tools needed.

Why It Works

A clogged air filter restricts oxygen to the engine, reducing power and efficiency. A clean filter can improve acceleration by 6-11% and fuel economy by 2-6%.
