Re: decoke?
 

sorry to resurrect an old thread, but I am about to add an aquamist HSF-4 to my MINI. I'm hoping any carbon build up will be taken care of with that.

Is that a correct assumption or should I see about getting a walnut blast too?

Thanks

Re: decoke?
 

Add wmi will not remove the existing build up. But it will minimise or eliminate the future build up after walnut blast.

A few new cars come with two sets of injectors, direct and port to combat build up.

port injection also reduces the particulates emissions at low to mid loads
