AUTOOL HTS558 Automotive Engine Intake Pipe Valve Clean Machine Valvetronic System Walnut Powder Sand Carbon Deposition Cleaner 110V

Have done 3 or 4 cars the results are incredible. Buy it you won't regret it. And the warranty is awesome 😎

Work as it states, I wish the vacuum suction was more powerful thou. Other than that, really made quick work out of these carbonized valve,

I bought this for blasting the intake valves of my 3.5 ecoboost v6 in my F150, worked great and made a 4 hour job a 20 minute job!

The Autool HTS558 worked well on a N14 Mini engine right out of the box with little modification to the nozzle length. I can’t wait to try it out on a engine with less awkwardly placed intake ports.My only complaint was that one of the vacuum wheels were broken when the unit arrived. I assume the wheel was broken from harsh shipping as the box was a little beat up when it arrived.

I still think it's pricey at closer to $500 but having a 2018 Kio Rio and a 2020 Subaru WRX but with direct injectors makes it worth it how easy it is to set up and use.First time was on the WRX and takes longer to close the valves than to do the blasting. didn't think the silicone inserts would be useful but used it out of the box and had no issues. I didn't see it came with walnut and bought some. Seems you can get more than one use per batch. 4 star cause to early to tell how good it really is or long it last.If you're in the fence about it just get and sell the service to make the money back or for multiple GDI you'll thank yourself having the all in one

Saved me hours of hand cleaning valves. Had a good seal with adaptors that removed a majority of the walnut media. Still recommend to blow out with air gun after cleaning to be careful. 3 minutes per valve had them looking like brand new!

This tool is very easy to use. It does an amazing job in no time. I wish I would have bought it sooner.

Works better than expected. Professional mechanic use.
