It restores airflow and combustion efficiency within 5 minutes, enhancing power, fuel economy, and reducing emissions. Ideal for routine maintenance, it prevents engine hesitation and starting issues, ensuring long-term reliability for diesel vehicles. ## Description Product Description Designed to provide an immediate and thorough cleaning effect, this advanced air intake cleaner targets the most critical components of a diesel engine’s air system. With a powerful formula that dissolves stubborn deposits such as gum, lacquer, tar, carbon, and varnish, it ensures that airflow remains unobstructed and combustion efficiency is maintained. Over time, these harmful residues accumulate in essential parts, leading to performance issues such as reduced power, increased emissions, and difficulties in starting the engine. This cleaner effectively removes these contaminants, restoring smooth and efficient operation. Equipped with a high-pressure jet spray, this cleaner ensures deep penetration into hard-to-reach areas. The strong spraying action enhances the cleaning effect, ensuring that deposits are quickly dissolved and eliminated. Unlike standard cleaning solutions that may require manual scrubbing or additional procedures, this powerful jet spray simplifies the process, making it faster and more effective. The targeted application method allows the formula to reach crucial components, including the air intake manifold, air flow sensor, inlet valves, turbo, and EGR system, ensuring a complete and thorough clean. By restoring optimal airflow towards the combustion chamber, this cleaner significantly enhances engine performance. A clear and unobstructed air passage is essential for efficient fuel combustion, leading to better power output, improved fuel economy, and reduced emissions. Regular use helps maintain these benefits, preventing the negative effects of carbon buildup and ensuring that the engine operates at peak efficiency. One of the standout features of this cleaner is its quick and easy application process. In just five minutes, it delivers a complete cleaning effect, making it an ideal solution for routine maintenance or addressing performance issues. Without requiring extensive mechanical work, it provides an immediate improvement in engine function, helping to prevent costly repairs and prolonging the lifespan of key components. In addition to restoring performance, this cleaner also plays a crucial role in preventing starting problems and irregular idling. Carbon accumulation in the air intake system, EGR valve, or air flow sensor can cause unstable idling, engine hesitation, and difficulties in starting. By keeping these components free from harmful deposits, this cleaner ensures smooth engine operation and long-term reliability. Regular application as part of an engine maintenance routine helps minimise the risk of unexpected issues, making it an essential product for maintaining diesel engines in optimal condition. Legal Disclaimer WE WILL NOT BE ABLE TO DISPATCHED THIS ITEM TO IRELAND, SCOTLAND OR CHANNEL ISLANDS DUE TO ROYAL MAIL RESTRICTIONS Box Contains 1 x Wynn's diesel EGR cleaner Review: Good stuff - Does the job when you take off the egr valve assembly.clean.with this and reassemble half hour job Review: Low end is as smooth as a hot knife through butter - I've had my car for 2 and a bit years, it's a moderately old car, 11 years and counting. I used this after some wynns 7in1 fuel additive. It was running considerably better after but decided to give it some egr/air intake cleaner anyway to keep on top of things. Honestly, the difference was subtle but noticeable, but I don't think there was much wrong with the engine to begin with. I only used half a can of this on my car, I don't think it needed more, and it took 20 minutes as it was, compared to the advertised 10. Maybe I just wasn't being aggressive enough with it. One thing I will note is that most people say to spray it into your air intake or just after the MAF, I read the instructions online and it tells you to put the spray in AFTER the intercooler, preferably into the air intake manifold directly (I put it in after the intercooler just before the throttle body), and also that the car should be run at just under 2k rpm, not idle like a lot of people do. After this, I took it on a run and instantly knew it had done something. The low rpm acceleration was as smooth as silk; I didn't even know there was anything wrong with the car before this. I just thought it was how diesels were. Again, I can't claim it helped my mpg or total power, but I didn't have much of a problem with that after the fuel additive, and my engine wasn't too dirty anyway, but smoothness it helped with. I will definitely be making this a part of my yearly maintenance schedule. ## Features - Causes serious eye irritation. - Extremely flammable aerosol. - May cause drowsiness or dizziness. - May cause respiratory irritation. - Pressurised container: May burst if heated. - Repeated exposure may cause skin dryness or cracking. - Toxic to aquatic life with long lasting effects. - car parts ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00BKC9LHA | | Best Sellers Rank | 570 in Automotive ( See Top 100 in Automotive ) 24 in Fuel Systems | | Brand | Wynn's | | Customer Reviews | 4.3 4.3 out of 5 stars (2,102) | | Date First Available | 24 Feb. 2013 | | Delivery information | We cannot deliver certain products outside mainland UK ( Details ).

If it is just a sticky valve then yes. This stuff is brilliant. Follow instructions to a tee, and don't worry if the engine chokes or makes weird noise during application. It's normal. All the best **Q: Could this damage the intercooler if sprayed into the inlet / MAF sensors?** A: This EGR cleaner won’t damage intercooler ( or hoses) providing you only spray in 1or 2 seconds at a time ,can spray in a few times providing you wait for engine revs to settle before next 1or 2 seconds spray. Best way is to remove MAF and clean off car. **Q: Will this work on a range rover sport v6** A: It should work on all diesel engines. However, if the fault/problem still persists, there may be a more serious problem with your EGR valve. The roller bearing had dropped out of mine, so it was a 'hard mechanical fault'. This cleaner may help, temporarily. **Q: Does it come with a straw to help with spraying correctly ?** A: Hi, yes it has a straw ## Customer Reviews ### ⭐⭐⭐⭐⭐ Good stuff *by M***H on 9 August 2026* Does the job when you take off the egr valve assembly.clean.with this and reassemble half hour job ### ⭐⭐⭐⭐⭐ Low end is as smooth as a hot knife through butter *by C***I on 4 August 2025* I've had my car for 2 and a bit years, it's a moderately old car, 11 years and counting.
