Benefits of Small Block Chevy Spark Plugs
If you have a small block Chevy and are looking for the best spark plugs, then you should definitely consider going with the best small block Chevy spark plugs. There are many benefits to using these types of spark plugs, and here are just a few of them.
One benefit is that they will help improve your engine’s performance. They can also help improve fuel economy because they create less emissions than other types of spark plugs. Additionally, they last longer than most other types of spark plugs, so you won’t have to replace them as often.
Buying Guide for Best Small Block Chevy Spark Plugs
In order to select the best small block Chevy spark plugs, you will want to consider several factors including the engine type, operating conditions and expected service life.If you are unsure about which spark plug is best for your application, consult your Chevrolet manual or a qualified automotive technician.
Operating Conditions
The first factor to consider when selecting small block Chevy spark plugs is the operating conditions of the engine. If the engine is mostly operated under light loads, then you will want a hotter-running spark plug. A hotter-running plug will help prevent deposits from building up on the electrode, which can eventually lead to misfires. Conversely, if the engine sees mostly heavy loads, then you will want a cooler-running spark plug so that deposits do not have a chance to build up and cause misfires.
Engine Type
Another factor that must be considered when choosing small block Chevy spark plugs is the type of engine. If you have an older model with cast iron heads, then you will need to use a different kind of spark plug than what is used in newer engines with aluminum heads. Cast iron heads require a larger diameter electrode in order to create an adequate electrical connection, so make sure to purchase plugs that specifically state they are for use in cast iron heads.
Expected Service Life The final factor that should be considered when buying small block Chevy sparks plugs is how long you expect them to last. If you are just looking for something that will get you by until your next oil change, then there are cheaper options available that will still get the job done. However, if you want something that will last longer and provide better performance throughout its lifespan, then it would be worth spending a few extra dollars on premium quality plugs.
