I saw this cleaner demonstrated by a popular automotive youtuber so I thought I would give it a try.
It worked extremely well on my Harley Davidson's throttle body.

This power foam seems to work pretty well when used properly. Be sure to take your intake filter and hose off and spray directly into the throttle body, while your engine is running around 1500-2500 rpms. After using the whole can, let it sit for 15 minutes and then drive fairly aggressively to clear out deposits. Your engine may run a little poorly at first and white smoke will flow from your exhaust. I plan on making this a routine with my oil changes.
Bottom Line
Yes, I would recommend this to a friend.

Effective product

Absolutely impressed how well this cleaned out my carbs on my 2 stroke outboard motor. Restored a nice steady idle and honestly I feel a little more response at the throttle. Boat isn’t any faster top end but I can tell it running a lot more steadily and I can climb through the rpm’s better rather than just jumping around from low end to top end speeds. Super impressive results in my experience
Bottom Line
Yes, I would recommend this to a friend.

This product is amazing! If you spray and let it sit in all the diaphragms it removes everything! I hit the carb with an airgun and its like new. Highly Recommended

Great Induction system cleaner

I used this for the first time yesterday. I changed a starter and had to take the intake off to get to the starter, so while I was at it I cleaned everything up. This stuff is amazing. I was surprised at how easy it worked and how munch carbon and gunk it took off. I would def recommend. I will say I flooded the engine with it. It instantly turns from foam to liquid, so less is more if you know what I mean.
Bottom Line
Yes, I would recommend this to a friend.

Didn't work

Used the stuff to try and get improved performance from my outboard, 90 hp Johnson; some cylinders have low compression, engine not achieving full power. Used the foam twice as directed, with no noticeable improvement; in fact, engine performance declined, as did the compression on two cylinders.
I have a twin turbo 3.5 ecoboost f150 and I personally notice a fuel economy difference from 14.6 miles per gallon, to 16.3 average. I’ve also noticed that every oil change the oil comes out cleaner and doesn’t smell burnt. I change my oil between every 1,000 to 2,000 miles. Overall engine performance is a little better, turbos spool up better and hold pressure higher and longer. Highly recommend this to anyone who is looking to switching to AMSOIL. Shipping and handling is also very fast and handled with care.
Bottom Line
Yes, I would recommend this to a friend.

SMOOTHED OUT ROUGH IDLE

My daughter and I did the Power foam on a 2020 KIA Sportage with 105k on it. Followed the directions, enjoyed the "smoke show" as well. Definitely helped clean valves (GDI 2.4), on cooler mornings you can head valve pings lightly when you accelerated while cold. It seems to have fixed that noise and cleaned throttle body to brand new. Great stuff.

It works! I can't see it working, but all their products are the best so I believe this will be too. I use it as a preventive for regular maintenance
