How can I improve the acceleration on my Vauxhall Insignia?

I've noticed that my Vauxhall Insignia's acceleration is not as good as it used to be. What can I do to improve it?

One thing you can do is to replace your air filter. A dirty air filter can restrict airflow and decrease engine performance. Also, make sure your spark plugs are clean and in good condition.

Another way to improve acceleration is to check your tire pressure. Low tire pressure can cause your car to work harder and decrease acceleration.

You may also want to check your fuel system. A clogged fuel filter can decrease power and acceleration. Consider having it replaced if it hasn't been changed in a while.
