Is it easy to change spark plugs?

Changing spark plugs takes about an hour (for a four-cylinder engine) and will save you at least a hundred bucks in labor. You can use the same old tune-up tools (ratchet, spark plug socket and gap gauge). You should use a torque wrench to tighten the plugs. But there's a way to get around that if you don't have one.

What does engine misfire feel like?

Engine Misfires
An engine misfire is a sensation that you should instantly recognize. Misfiring will cause increased exhaust emissions, reduced fuel economy and reduced engine power. A single misfiring spark plug can dump enough raw fuel into the exhaust to overheat and damage the catalytic converter.

Can new spark plugs increase horsepower?

In short, yes, in some situations spark plugs can increase horsepower. These 'massive' gains of one or two per cent generally won't be exceeded, even if you're replacing really old and worn spark plugs for new ones. In this case, your essentially just restoring your car back to its peak performance.

Are Iridium plugs worth it?

It is estimated that iridium spark plugs will last for at least 40,000 miles but they've been known to go up to 60,000 miles or even 80,000 miles. This is the amount of mileage that most people put on their cars before they get a new one. So, an investment in these spark plugs would surely be worth it for this.

Can bad spark plugs cause transmission problems?

Wait, a bad spark plug? So, if a spark plug is worn, the extra load, combined with the leaner mixture can degrade the spark, causing an intermittent misfire. And since there's no cushion between the engine and transmission, you feel every misfire through the entire car.

Which is better iridium or platinum spark plugs?

Iridium is said to be six times harder and eight times stronger than platinum with a 700° higher melting point. Iridium spark plugs have extremely fine electrodes while retaining excellent wear characteristics. Thanks to its strength, iridium spark plugs can last up to 25% longer than comparable platinum spark plugs.

Do you have to replace all spark plugs at once?

Spark plugs are cheap, you change them in sets as you do with brakes or spark plug wires. You want all of your spark plugs to match and have nearly the same levels of electrical resistance as all of the other plugs. I don't think anyone on this site would only change one spark plug on their own vehicle. Exhale.
