At a typical garage
The intake manifold distributes air (and fuel on port-injected engines) evenly to each cylinder; carbon buildup on direct-injection engines restricts airflow and reduces performance significantly. BRISTOL 603 intake manifold service costs $2229–$10146.
Warning signs you need this repair
- Rough idle and reduced power (carbon buildup on intake valves)
- Hesitation under acceleration
- Check engine light with lean mixture or vacuum leak codes
- Poor fuel economy
- Misfires caused by uneven air distribution between cylinders
Typical parts included
- Intake manifold
- Intake manifold gasket
What affects the price
- Walnut blasting vs chemical cleaning vs manifold removal (walnut blasting is most effective)
- Direct injection engines require cleaning more frequently than port injection
- Whether gaskets and sensors are replaced during the job
