. Here’s a quick

2013 Honda Civic horsepower care guide

Air Filter: A clogged air filter restricts airflow to the engine, essentially choking it. Replace your air filter every 15,000-30,000 miles, or more often if you drive in dusty conditions. This is a simple, inexpensive DIY that makes a noticeable difference.
Spark Plugs: Worn or fouled spark plugs lead to incomplete combustion, wasting fuel and reducing power. Consult your owner’s manual for the recommended interval (typically 60,000-100,000 miles for iridium plugs) and replace them with OEM-spec plugs or a suitable aftermarket equivalent.
Fuel System: A clean fuel system ensures proper fuel delivery. Use a high-quality fuel system cleaner every few oil changes. If you suspect issues, consider replacing your fuel filter (if serviceable on your model) or having injectors professionally cleaned.
Oil Changes: Fresh, clean engine oil reduces friction, which can rob your engine of horsepower. Stick to Honda’s recommended oil type and change intervals. Synthetic oils often provide better protection and can help the engine run smoother.
Tire Pressure: While not directly engine-related, incorrect tire pressure increases rolling resistance. This means your engine has to work harder to move the car, effectively reducing the power available for acceleration. Check your tire pressure regularly and inflate to the recommended PSI on your door jamb sticker.
Valve Adjustment: For some Honda engines, particularly the K-series in the Si, a periodic valve adjustment is recommended (check your owner’s manual). Improperly adjusted valves can lead to rough idling, reduced power, and decreased fuel economy.

These basic maintenance items are your first, most cost-effective performance upgrades.
