how to clean intake manifold

Want to avoid loss of power? Getting intake Manifold runner or Swirl Flap issues?

Our diagnosis and engine carbon cleaning is your best option!

Why does it get clogged up? As part of the emissions system, some of the dirty exhaust gases are diverted back into the intake manifold to aid reducing combustion temperatures, this in turn reduces combustion temperature and therefore the poisonous NOx gas that we are all so concerned about breathing in. The downside to this is that some of the carbon, resins, oil vapor residues that present in the exhaust gases coat the inside of the intake manifold forming 'carbon build-up'. Over time this builds up to a point that you'd be shocked the engine is actually able to breath and run!

This leads to symptoms such as poor engine performance, lowered fuel efficiency, engine management warning lights and the limp-home-mode being activated (restricted performance), lowered fuel economy and rough idling. We have a great wealth of knowledge and specialise in the diagnostics and cleaning of the EGRintake manifold and swirl flap system. This includes live data analysis using dealer level diagnostics equipment that we include in all our intake manifold cleaning services.

How do we clean the intake manifold and swirl flaps? Firstly we'll use our dealer level diagnostics equipment to assess the engine management error codes and complete live data analysis. Then assuming the vehicle is fit for cleaning we use our 1, 2, 3 or 4-stage engine carbon cleaning system that includes our world-leading Hydrogen carbon cleaning and our unique chemicals. This means in the majority of instances there is no requirement to remove the manifold for cleaning or replace it with a new part. On completion of the job, which takes approximately 45-60 minutes, we'll reassess the engine management system and reset any fault codes.

Large Diesel but lots of small journeys since using the train a lot, so knew the carbon would be an issue (as cost me £900+ to get it sorted a few years back in similar case).
Anyhow, noticed it was low on power in low revs and running with a K&N air filter so replaced (not recharged) and improved slightly, then cleaned out EGR valve of lots of carbon, issue still there.
Carbon cleaned my car and the other halfs (worth the cash as a prevention and with a generous 2nd car discount to be honest) and the improvement is brilliant. Smoother revving and power delivery, better mpg and quieter tickover undoubtedly. Unfortunately didn't resolve my issue as I later found it was my MAF sensor which I later cleaned and now runs lovely. Still glad I tried the carbon clean as my experience for sheer improvement was way above expectations. I will use again and may even carry out yearly as a preventative maintenance on my cars as they all clog. The treatment makes my car feel like new.

A very friendly and professional service. Adam even worked around me, he came and completed the clean at my work.

Very knowledgeable, and gave me good aftercare advice.

I would highly recommend this service to my friends and family.

Had my Audi s3 remapped. big difference to the car, quick professional service and good knowledge.

Had James out to do a stage 1 map and egr delete on my mk5 golf gttdi and what a difference in power especially when over taking, mpg is also up. Well recommend and will use again. Cheers

Red did amazing job on My Audi A4 2.0TDI Stag 1 carbon clean. You can tell the massive difference and I will be seeing you again for My remapp.
Red is such a great guy. He explained the whole process and spent much longer than was expected to make sure that all was working correctly.

Recently had a stage 1 map put on my golf r and the results are serious definitely worth it for anyone considering James is very accommodating and was able to come out to me at short notice great guy and a great service will definitely use in the future ??
Wayne Doran

He came to me at a convenient time and place that suited me, friendly and polite. The car itself feel's considerably better and a lot smoother. The mpg is better too. I'm a happy and satisfied customer.

Kieran Stewart

The customer service was absolutely outstanding, really put my mind at ease and explained everything very professionally, highly reccmond this guy he will defiantly sort you out. Top notch service I'll be calling again.

the nicest person to talk to. highly recommended. seen a big difference in throttle response and more power and a silent engine in my bmw e46 328ci that you think its off. amazing job thanks mate

Michael Jackson

I was very skeptic all at first and people said it was snake oil but after having it done and the injector additive the car idles and feels a lot better on throttle response, I drove all the way back three hours from jae and the change was very noticeable on a 130 thousand mile engine it was no longer tired and sluggish, I would recommend this to any one with a high miles car.

Why clean the Intake Manifold and Swirl Flaps?

The intake manifold a set of tubes configuration to deliver the air to the cylinders. In all engines, this air comes through a filtered air intake designed to keep the engine and components such as the manifold clean. However, with the need to make engines more efficient and reduce emissions manufacturers have introduced an EGR (Exhaust Gas Recirculation) system into the engine. The problem occurs due to the recirculation including oil, unspent fuel, and other deposits that as they enter the manifold then stick to the walls of the manifold tubes and begin to clog them up. The engine then receives reduced air flow, starts to become inefficient and doesn't burn all the fuel. This leads to loss of performance and increased emissions and pollution.

Problems that may occur from a dirty manifold include uneven and a noisy idle (usually the first sign of the issue), a tendency to stall, misfires and hesitation (especially when the engine is cold).

Cleaning your Intake Manifold and Swirl Flaps

There are numerous ways to resolve a clogged intake manifold and/or swirl flaps with varying prices.

The costliest option is to replace the component. Dependent on the vehicle manufacturer and engine type expect this to be in the region of high £100's, if not £1000's.

The moderately expensive alternative is to if possible manually clean them. Most mechanics will recommend this – Why? Because they'll earn well from the extensive hours it takes to complete the job. The price will be dependant on how bad the clogging within the manifold, labour rates and engine type but expect it to be in the £100's.

The most cost-efficient solution would be our engine carbon cleaning service.
