Will changing my spark plugs improve performance?
The short answer is Yes, when you replace the spark plugs and wires can increase your vehicle’s performance. New spark plugs help keep your engine at its peak performance and efficiency levels. Misfires caused by worn spark plugs will cause older vehicles to buck, stall, run rough or start slow.
Should engine be warm or cold when changing spark plugs?
Changing Spark Plugs When The Engine Is Cold Installing a spark plug with the engine hot can change the torque specification. Installing a spark plug with the engine hot can change the torque specification and how the threads on the engine and spark plug interact.

What do cars have instead of sparkplugs?
Newer vehicles have a coil-on-plug ignition system that eliminates electrical problems caused by worn-out spark plug wires. The industry required a more accurate control of spark and fuel delivery because of the need to annually boost fuel economy and reduce emissions.
Do modern cars use spark plugs?
We asked the experts and here’s what we found out. Modern gas-powered engines still come with spark plugs to initiate ignition of the air-fuel mixture in the cylinder. They are responsible for providing the energy that these vehicles need to get the engines to start and propel them forward on the road.
Can spark plugs add horsepower?

What is the cheapest way to increase horsepower?
More fuel/air equals more horsepower. Cold-air intakes also (as the name implies) draw cooler air from outside the car engine compartment. Cooler air is denser, again resulting in the computer increasing the amount of fuel, helping the engine increase horsepower.
What is a tune-up?
A car tune-up is a type of preventive maintenance performed on a vehicle to ensure it continues to perform well. The tune-up should also include cleaning or replacing the spark plugs and, on older cars, the distributor cap and rotor.
