How many spark plugs does a car have?
How many spark plugs does an average car have? My dad and I are building a car together for fun. We need to install spark plugs, but I’m not sure how many we need.

Wow, that sounds like a neat way to spend quality with your dad! Spark plugs are essential to generate power for a vehicle, so you definitely want the right amount.
Typically, the number of spark plugs required will depend on the number of cylinders a car has and the size of its engine. There is one spark plug for every cylinder, so if an
engine
has four cylinders, there are four spark plugs.A standard vehicle would usually have four cylinders and four spark plugs. That said, there are exceptions when it comes to HEMI engines, which are usually found in muscle cars. One cylinder will require two spark plugs.
If you’re still unsure after looking at the engine and its cylinders, check the owner’s manual. The manual should give you the exact number of spark plugs needed.
When the car is built and ready for a test drive, remember you’ll need a car insurance policy. If you want to save money on car insurance, the
