WYNNS Petrol EGR Cleaner is an engine cleaning spray for petrol cars that tackles carbon and deposit build-up across the air intake, MAF sensor, inlet valves, turbo and EGR to help restore airflow and combustion. Regain smoother starts and steadier idling, whether tackling a reluctant commuter or a tired family car. Is this the quickest way to sort stubborn intake issues without dismantling the engine?
⚡ At a Glance
- • Cleaning Action: High-pressure spray penetrates crevices to break down gum, lacquer, tar, carbon and varnish
- • Best for: Owners of petrol cars with clogged MAF, EGR, inlet valves or turbo-related breathing issues
- • Not ideal for: Diesel engines and jobs that require full component teardown and precision machining
High-pressure jet formulation targets MAF sensors, inlet valves, turbo and EGR to remove stubborn deposits. The process restores airflow and helps return combustion behaviour to a more stable state.
Restored engine breathing – with a high-pressure jet spray
High-pressure spray delivers solvent deep into the air intake tract and sensor housings, weakening and removing deposits such as carbon, gum and varnish without having to access internal ports. Precision application reaches MAF sensor, inlet valves, turbo inlet and EGR passages to free blocked airflow paths.
Cleaner air reaching the combustion chamber improves fuel burn and throttle response, reducing flat spots and hesitation. Expect more consistent idling and a smoother drive after treatment.
Fast maintenance turnaround – thanks to a five-minute cleaning process
A short contact time is specified where chemicals act immediately on deposits, and the pressurised spray accelerates penetration so dislodged residues flush away. The method avoids dismantling parts for the majority of common build-ups.
Quick servicing makes it practical for routine maintenance or a rapid remedial visit at home or in a workshop. Minimal downtime keeps cars on the road and reduces labour for straightforward clean-ups.
Targeted sensor and valve recovery – with a formulation aimed at MAF, EGR and inlet valves
Formulation chemistry focuses on softening and dissolving contaminants that impair sensor readings and valve movement, helping restore accurate airflow measurement and valve operation. Cleaner sensor passages reduce false readings that lead to unstable mixtures and misfires.
Improved sensor accuracy and freer valve movement help prevent misfires, stabilise idle and reduce hard starts. Drivers should notice firmer acceleration and fewer intermittent faults related to clogged intake components.

❓ Frequently Asked Questions
Q: Can this be used on diesel engines?
A: Formulated specifically for petrol engines, suitability for diesel applications is not indicated in the provided information.
Q: Do I need to remove the inlet manifold or EGR valve first?
A: No dismantling is required for typical applications, the cleaning process is designed to work without dismantling engine parts.
Q: How long does the cleaning take to show results?
A: Cleaning typically takes around five minutes, with performance and idle stability often improving immediately after treatment.
🏆 Our Verdict
Best suited to petrol car owners and workshop technicians dealing with clogged intakes, fouled MAF sensors or sluggish turbo response. High-pressure spray action combined with a five-minute application and targeted chemistry for MAF, inlet valves and EGR is the key selling point. Offers clear long-term value by helping to prevent recurring driveability issues and maintaining efficient combustion.
