QPKING Walnut Sand DE-Carbon Cleaner HTS558 Walnut Blaster Cleaner Automotive Valvetronic System Carbon Deposition Cleaning Engine Intake Pipe Valve Clean Machine 110V/220V

This thing is nice! It's a vacuum ans sandblasted all in 1. Cleanest carbon buildup, gunk, gum, varnish, deposits on intake valves the by product from burning gasoline. Frees up horsepower and fuel economy! I'm a professional mechanic and there are lots of times that I remove an intake manifold to change plugs or valve cover gasket and when I see the valves and the carbon buildup, sometimes I cannot believe my eyes! And I try to clean it out but still can only reach half of the valve. This product solves that problem. This product cleans the intake valves like new, with no harm to the engine. This is a must have for every technician to add to their tool arsenal. Atleast in my opinion, each automotive repair facility should have 1! The one that I'm employed at does not, so I bought one, and I think it's amazing!

I have a direct injection motor with 93k miles and the valves were caked with deposits. After a quick clean up of the bulk of the crusty mess, this blaster made quick work of making the valves look like new. Huge improvement in throttle response.

could use some more adapters for it. however, there was enough in the box to make it work so it’s still going to get a 5 star from me.

Peace of crap. Does not suck up the walnuts with the adapters that it came with and the trigger on gun does not stop the flow of air when you let go of trigger. Only chose one star because I had to. It's a no star for me since the item does nothing that it's intended to do.

Works as advertised. You may need specialised nozzles for certain vehicles. I had to replace the air fitting as it was not Nitto.

This blaster its bin used at the shop works very well
