I have a MK2 Ford Focus Zetec and the engine noise is not overly loud, but id like to quieten it down a bit. Ive changed oil, sparkplugs etc to see if it had anything to do with this, also tried injector cleaners etc. Still the same
Ive heard that Zetecs just have this noise even on the newer vehicles....... or im just being picky.
Ive heard of these
Does anyone have any advice on these?. Do they quieten down the sound of the engine from inside and outside of the vehicle?
I was also looking at this for lining my bonnet with as well
Would lining my boot with this be safe?
If anyone can suggest any other products instead of the ones ive listed, please do
