Spark Plug Upgrade for Turbocharged Cars: Achieving 10-15 Hp Gains with $50 Parts
Upgrading the spark plugs in your turbocharged vehicle can lead to noticeable performance improvements. This simple modification can yield gains of 10-15 horsepower, all for a relatively low cost of around $50. In this article, we will explore the benefits of spark plug upgrades, the types of spark plugs available, and the installation process.
Why Upgrade Spark Plugs?
Turbocharged engines operate under higher pressures and temperatures, making the choice of spark plug critical. Standard plugs may not be able to handle the demands of a turbo setup, leading to misfires and decreased performance. Upgrading to high-performance spark plugs can improve combustion efficiency and overall engine performance.
- Improved combustion efficiency
- Increased horsepower
- Better fuel economy
- Enhanced throttle response
Types of Spark Plugs for Turbocharged Cars
When selecting spark plugs for a turbocharged vehicle, there are several types to consider. Each type has its own advantages and is suited for different applications.
- Iridium Spark Plugs: Known for their durability and longevity, iridium plugs can handle higher temperatures and pressures.
- Platinum Spark Plugs: These offer a good balance between performance and lifespan, making them a popular choice for many turbo applications.
- Copper Spark Plugs: While they provide excellent conductivity, they have a shorter lifespan and are best for racing applications.
- Multi-Ground Electrode Plugs: These plugs can improve ignition and combustion efficiency by providing multiple points of spark.
Choosing the Right Spark Plug
When choosing the right spark plug for your turbocharged engine, consider the following factors:
- Heat Range: Select a spark plug with a heat range appropriate for your engine’s performance level.
- Gap Size: Ensure the gap is set according to your manufacturer’s specifications for optimal performance.
- Brand Reputation: Choose reputable brands known for high-performance spark plugs.
Installation Process
Installing new spark plugs is a straightforward process that can be done at home with basic tools. Here’s a step-by-step guide:
- Gather Tools: You will need a socket wrench, spark plug socket, torque wrench, and anti-seize lubricant.
- Remove Engine Cover: If applicable, remove the engine cover to access the spark plugs.
- Disconnect Spark Plug Wires: Carefully disconnect the wires from the old spark plugs.
- Remove Old Spark Plugs: Use the spark plug socket to remove the old plugs, turning counter-clockwise.
- Prepare New Spark Plugs: Apply a small amount of anti-seize lubricant to the threads of the new plugs.
- Install New Spark Plugs: Hand-tighten the new plugs and then use a torque wrench to tighten them to the manufacturer’s specifications.
- Reconnect Wires: Reattach the spark plug wires in the correct order.
- Replace Engine Cover: If removed, put the engine cover back in place.
Expected Results
After upgrading your spark plugs, you can expect to see improvements in your vehicle’s performance. Many drivers report gains of 10-15 horsepower, enhanced throttle response, and better fuel efficiency. Additionally, your engine may run smoother and more reliably.
Conclusion
Upgrading the spark plugs in your turbocharged car is a cost-effective way to boost performance and enhance your driving experience. With just $50 and a few hours of your time, you can achieve significant horsepower gains and improve overall engine efficiency. Consider this upgrade as part of your vehicle’s performance tuning strategy.
