The Foundation of Power: Essential 2017 Honda Accord Horsepower Care Guide
Before you even think about modifications, the single most impactful thing you can do to ensure your 2017 Honda Accord performs at its peak is meticulous maintenance. Neglecting routine service is the quickest way to lose horsepower and efficiency. This section covers the core elements of a robust 2017 Honda Accord horsepower care guide.
Regular Oil Changes: The Engine’s Lifeblood
Clean engine oil is vital for reducing friction, cooling engine components, and ensuring all moving parts operate smoothly. Dirty, old oil increases wear and can actually rob your engine of power.
- Frequency: Follow Honda’s recommended schedule, typically every 5,000-7,500 miles or as indicated by your Maintenance Minder system.
- Type: Use the recommended synthetic or semi-synthetic oil (e.g., 0W-20 for the 4-cylinder, 5W-20 for the V6). Check your owner’s manual.
- DIY Tip: Always use a new oil filter (e.g., Fram Tough Guard, Bosch Premium) with every oil change. Have a drain pan, a wrench for the drain plug, and an oil filter wrench ready.
Air Filter: Breathe Easy, Perform Better
Your engine needs a steady supply of clean, cool air to make power. A clogged air filter restricts airflow, forcing your engine to work harder and reducing horsepower. Think of it like trying to run with a hand over your mouth.
- Check Regularly: Inspect your air filter every 15,000 miles or once a year, more often if you drive in dusty conditions.
- Replacement: If it’s dirty, replace it with a quality OEM or aftermarket filter. This is an easy DIY job, usually requiring just a screwdriver to open the airbox.
Spark Plugs: Igniting Performance
Spark plugs are responsible for igniting the air-fuel mixture in your cylinders. Worn-out or fouled spark plugs lead to misfires, reduced fuel efficiency, and a noticeable drop in horsepower. The V6 engine, with its six plugs, is particularly sensitive to this.
- Lifespan: Modern iridium-tipped spark plugs can last 60,000-100,000 miles. Don’t wait until you feel a problem.
- Replacement: This can be a bit more involved, especially for the V6 where you might need to remove the intake manifold for the rear bank of cylinders. If you’re not comfortable, this is a job for a professional technician.
Fuel System Health: Injecting Power
A clean fuel system ensures your engine receives the correct amount of atomized fuel. Clogged fuel injectors or a dirty fuel filter can starve your engine of fuel, impacting power.
- Fuel Filter: The 2017 Accord’s fuel filter is typically integrated into the fuel pump assembly inside the fuel tank and is usually considered a “lifetime” part. However, using quality fuel and occasional fuel system cleaner can help.
- Fuel Injectors: If you suspect issues, a professional can test and clean your injectors. Regular use of a quality fuel system cleaner (e.g., Techron, Sea Foam) every few thousand miles can help prevent deposits.
Transmission Fluid: Smooth Shifts, Efficient Power Delivery
The transmission plays a crucial role in getting power from the engine to the wheels. Clean, fresh transmission fluid ensures smooth shifts and efficient power transfer. Old, burnt fluid can lead to slippage and power loss.
- CVT Care (4-Cylinder): CVTs are particular about fluid. Use only Honda Genuine CVT Fluid. Follow the recommended change intervals, often around 30,000-60,000 miles, depending on driving conditions. This is often a DIY job for careful mechanics.
- Automatic Transmission Care (V6): Use Honda Genuine ATF DW-1. Change intervals are similar to CVTs.
By keeping up with these fundamental maintenance items, you’re not just preserving your Accord’s reliability; you’re ensuring you’re getting every single bit of the original 2017 Honda Accord horsepower it was designed to deliver.
