## Overview

MANNOL 400ml Intake Valve Cleaner is a powerful automotive maintenance solution designed to quickly remove tough carbon, soot, and oil deposits from intake valves. It protects against corrosion and oxidation, improves cold starts, stabilizes idle speed, and reduces fuel consumption, ultimately extending the life of your engine’s intake system and lowering repair costs.

## Description

Intake Valve Cleaner-a highly effective tool for cleaning the intake system of gasoline engines up to the intake valves and in the most inaccessible places from all the typical dirt without disassembling the system. In most cases, a single application is sufficient to bring the intake system into perfect condition. As the idling valve (IAC) is operating, deposits gradually accumulate on it, which ultimately affects the circulation of air and gases. This reduces engine power and acceleration, disrupts the smoothness of idling, and significantly increases fuel consumption. Signs of a clogged idle valve may include: - Difficult start-up; - Intermittent idling, as indicated by jumping tachometer readings; - Slow speed reduction when you press the clutch pedal while driving; - Black smoke from the exhaust pipe. Properties: - Quickly, effectively and carefully removes dirt, soot, carbon, resinous and oil deposits and other most difficult to remove and old dirt; - Further protects the intake system elements from corrosion and oxidation, prevents the formation of new dirt and deposits on them, provides functionality and mobility of moving parts, - extending the service life of the intake system and reducing repair costs; - Facilitates cold start, restores the uniformity of idle speed, and reduces fuel consumption; - Contains acetone-aggressive to paint surfaces and plastics; - Safe for catalytic converters, oxygen sensors and turbochargers. Application: shake the balloon well before use. The product must be sprayed behind the air flow meter (the product must not get on it) for at least 30 seconds (depending on the degree of contamination) when the engine is idling (at least 2000 rpm). If there are particularly persistent deposits on the throttle, inside the intake manifold, or on the intake valves, the cleaning procedure can be repeated. After application, allow the engine to run for about 20 seconds at min. 2000 rpm, so that possible residues in the intake system can burn.

Review: Like oxygen to my lungs - 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.
Review: Excellent product and flawless service - Had a problem with my Ford C-max. Irregular idling revs. Very sluggish uptake if you slowed in second gear and then tried to accelerate again in same gear (which you do all the time in London!). Also issues with it spluttering and stalling at junctions and when reversing into parking spots. This product did exactly what I hoped it would do. Sprayed it into the throttle valve and I wiped away the deposits I could see. Image 1 is before, image 2 is after obviously. Gave it a good spray inside the throttle body too to be sure. Here’s a tip, don’t push the valve open manually if it’s electronically operated as that has the potential to damage. Instead turn the ignition to power on (don’t start the engine), then brace the accelerator pedal hard down inside the car to open the valve. The engine will be a bit rough immediately after treatment. I had revs spiking erratically and lots of spluttering. I thought I’d messed up, but it just needed a short run to settle everything down. Back to the product. It’s great stuff! Having used it it’s like driving a different car!!! Seller was great too, despatched promptly, no issues!

### ⭐⭐⭐⭐⭐ Clean intake valve
*by M***E on 10 May 2025*

Cleaned the intake valve very well. I was surprised how much dirt and oil was actually removed. Is a much better car now
