Check Regularly: Inspect your air filter every 15,000-30,000 miles, or more often if you drive in dusty conditions.
Replacement: A new, clean air filter allows your engine to ingest the maximum amount of oxygen, leading to better combustion and preserving horsepower.

This is a simple DIY job that can yield noticeable benefits for your engine’s breathing and overall power.

Spark Plugs: Igniting Your Potential

Spark plugs provide the crucial spark that ignites the air-fuel mixture in your cylinders. Worn or fouled plugs lead to misfires, reduced combustion efficiency, and a significant drop in power.

Interval: Refer to your owner’s manual, but generally, quality iridium spark plugs can last 60,000-100,000 miles.
Symptoms of Bad Plugs: Rough idle, sluggish acceleration, reduced fuel economy.

Replacing spark plugs can restore lost power and improve overall engine smoothness. For turbo engines, proper spark is even more critical for consistent power delivery.

Fuel System Health: Clean Power Delivery

Clean fuel injectors ensure a precise spray pattern for optimal fuel combustion. Over time, injectors can get clogged, leading to poor fuel atomization and reduced power.

Fuel Quality: Use reputable brands of gasoline. While the 1.5L can run on regular, the 2.0L turbo benefits from premium fuel for maximum performance and to prevent pre-ignition.
Fuel System Cleaner: Occasionally using a high-quality fuel system cleaner (e.g., Techron, Sea Foam) can help keep injectors clean.

A healthy fuel system is paramount for consistent and efficient honda accord 2018 horsepower.

Transmission Care: Putting Power to the Pavement

The best engine in the world is useless if the transmission can’t efficiently transfer power to the wheels. Your Accord’s continuously variable transmission (CVT) in the 1.5L, or 10-speed automatic in the 2.0L, requires specific care.

Fluid Changes: Follow Honda’s recommended intervals for transmission fluid changes. This is crucial for smooth operation and preventing wear.
Proper Operation: Avoid aggressive driving when the transmission is cold.

A well-maintained transmission ensures that every bit of that honda accord 2018 horsepower reaches the pavement effectively.
