I use it since 2017 every 6 months to clean up the throttle gate for my subaru WRX and jeep wrangler does the job well

Lovely

Very good product took off all the carbon and my car is running so good

Amazing product, top quality and the attached hose makes it super easy.

better than ACDelco

Lo utilice como especifiba, gasté medio bote y al circular con el coche varios kilómetros el testigo de avería se apagó. Ahora funciona perfectamente.

it is very good, it do the job exactly. Highly recommended ... sure i will buy again.... already done :)

No hose in bottle Package very bad

Gave my engine’s lungs a shower — and now it breathes like a champ. I grabbed this MANNOL Intake Valve Cleaner because my van’s engine was beginning to grumble, cough, and act like it was trying to sing for help every time I stopped at traffic lights. The intake tract was probably uglier than my DIY paint jobs. One spray later, and I swear the engine took a deep, relieved breath. All that built-up soot, oil and carbon – you know, the stuff that accumulates on idle valves, throttle-bodies and intake passages – dissolved like it got an eviction notice. After a short run at idle (as per instructions), the rough idling and hesitation vanished. Things started smoother, the idle steadied, and the revs responded properly — no more lag when pressing the clutch or gunning the throttle. Pros: Cleans carbon, oil, resin and soot from intake valves and throttle areas without needing to dismantle the intake. Can improve idle smoothness, throttle response, and fuel-air flow — good for older engines or ones that get stressed often (like vans doing plumbing runs). Simple spray-on application. Quick job, minimal faff compared to a full intake teardown. Potential caveats: It’s a strong aerosol (contains solvents) — so don’t be messing about with painted plastics or bare paint around the engine bay when spraying. You still need to follow instructions (engine temperature, revs, after-spray run) — otherwise you’ll get less benefit. Five stars. If your engine’s breathing feels clogged, this cleaner is like a plumbing snake for your intake — it clears the crap, gets airflow flowing, and makes everything run smoother.
