How to improve performance in a Vauxhall Astra?

I have been experiencing some issues with the performance of my Vauxhall Astra. It seems to be struggling when accelerating and has a lack of power. I have tried changing the spark plugs and air filters but the issue persists. Any suggestions on how to improve the performance of my car?

One common cause for poor performance in a Vauxhall Astra can be a clogged fuel filter. It is important to replace this regularly to ensure proper fuel flow and optimal engine performance. You can also try using a fuel system cleaner to remove any build-up in the fuel lines.

Another thing to consider is the state of your tires. Make sure they are properly inflated and have enough tread depth. Worn tires can greatly affect the performance of your car.

Have you checked the condition of your ignition coils? These can wear out over time and affect the performance of your engine. It may be worth replacing them if they are showing signs of wear.
