Spark plugs are like the heartbeat of your car. Simply put, if they stop working properly it will make your car slow, sluggish and difficult to start. The good news is changing your spark plugs is, in most cases, an easy job, taking no more than 1/2 hour.
Normally you’d replace your plugs annually with a standard spark plug, but it’s worth considering the benefits a premium spark plug will give you.
Premium spark plugs produce a brighter, more consistent spark and will make sure your getting the most from your engine. With fuel prices going through the roof, it’s worth fitting a part that will improve the power and efficiency of your engine. Premium spark plugs are known to have an improving effect on your petrol consumption.
Import cars are going to see the biggest benefit, as premium plugs can help reduce the impact of fuel differences between Japan and the UK.
Sure-fire signs your plugs are not working properly are:
- Getting less mpg out of your car
- An erratic idle
- Not starting easily (think we’ve all had this on a cold morning)
- Poor acceleration (will get worse over time)
- Stalling for no good reason
If you have any of these symptoms it might just be time to check and change your plugs.
