      Excellent results
      By  KEVIN,  a  Verified Buyer  on  April 18, 2026
      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.
      Bottom Line
      Yes, I would recommend this to a friend.

      It actually works
      By  DAMON,  a  Verified Buyer  on  February 08, 2026
      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
      By  CHRIS,  a  Verified Buyer  on  January 03, 2026
      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.

      Power Foam
      By  Paramotor School,  a  Verified Buyer  from  PA, VA, GA, FL  on  November 19, 2025
      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
      Bottom Line
      Yes, I would recommend this to a friend.

      Great Induction system cleaner
      By  TIM,  a  Verified Buyer  on  October 17, 2025
      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
      By  joe AL,  a  Verified Buyer  on  June 22, 2025
      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 like the foam
      By  JAMES,  a  Verified Buyer  from  Georgia  on  February 28, 2025
      The best part of this product is the foaming action. It doesn't evaporate very quicky so it cleans longer.
