Restore Performance and Efficiency Without Replacement
Improve airflow, throttle response and fuel economy
Over time, carbon deposits and oil residue build up in intake systems, throttling airflow and reducing engine efficiency. On large American vehicles, especially turbocharged V6 and V8 engines, this buildup can cause rough idling, poor throttle response, increased fuel consumption, and even fault codes.
At Welshpool Auto Service, we specialise in cleaning intake manifolds, EGR pathways, and throttle bodies – helping your engine breathe easy again.
What We Clean
We clean all key air and fuel delivery components, including:
- Intake manifolds
- Inlet ports
- Throttle bodies
- EGR valves
- Intercooler piping
- Upper and lower plenums
- Boost sensors and MAP sensors
This service is ideal for vehicles like the RAM 1500, Chevrolet Silverado, Ford F-Series, GMC Sierra, and other large petrol or diesel-powered utes and trucks.
Why It Matters
Carbon and soot buildup can:
- Restrict airflow
- Affect fuel-air mixture
- Reduce power and torque
- Cause check engine lights
- Trigger limp mode or poor fuel economy
Cleaning the intake and manifold helps restore lost performance and reduce long-term wear on your engine.
Our Process
- Component Removal – We remove and inspect all parts to be cleaned.
- Chemical & Vapour Cleaning – We use non-corrosive chemicals and vapour blasting to remove carbon, soot, and oil film.
- Ultrasonic Treatment (if required) – For stubborn buildup and internal galleries.
- Sensor and Surface Inspection – MAP, boost, and IAT sensors are cleaned and checked.
- Reassembly with New Gaskets – Ensures airtight sealing and correct torque specs.
When Should You Get It Done?
- During major servicing intervals (e.g. 90,000km+)
- When you notice sluggish performance
- After a tune or intake modification
- As part of a DPF or EGR clean
