While Individual Throttle Bodies dramatically improve airflow, throttle response and engine performance, they also require effective filtration to protect the engine from dust, dirt and airborne contaminants. The Rennen ITG Air Filter Assembly provides this protection while maintaining the unrestricted airflow characteristics that make Barrel ITB conversions so desirable.
Designed to integrate seamlessly with the Rennen by JSR induction system, this filter assembly offers an excellent balance between airflow, filtration efficiency and engine protection, making it ideal for fast road, touring and occasional track use.
What Does the ITG Air Filter Assembly Do?
The ITG Air Filter Assembly protects the engine by filtering incoming air before it enters the throttle bodies and combustion chambers.
Its primary functions include:
- Preventing dirt ingestion
- Protecting cylinders and piston rings
- Protecting valves and valve seats
- Maintaining clean airflow
- Supporting engine longevity
- Preserving performance
- Reducing engine wear
The filters allow the engine to breathe freely while preventing harmful contaminants from entering the intake system.
Why Are Air Filters Essential on ITB Systems?
Individual Throttle Bodies are designed to maximise airflow and engine response. Without air filters, debris and contaminants can be drawn directly into the engine.
Proper filtration helps:
- Protect expensive engine components
- Prevent premature cylinder wear
- Maintain engine reliability
- Reduce intake contamination
- Support consistent tuning
- Preserve airflow characteristics
- Improve long-term performance
For road-driven vehicles, filtration should always be considered an essential part of any ITB installation.
Why Choose ITG Foam Filters?
ITG filters are widely recognised throughout motorsport and performance automotive applications for their excellent combination of airflow and filtration efficiency.
Benefits include:
- High airflow capacity
- Excellent filtration performance
- Lightweight construction
- Washable and reusable design
- Motorsport-proven technology
- Long service life
- Consistent airflow characteristics
- Ideal for high-performance engines
The foam filter construction allows superior airflow while maintaining effective protection against airborne contaminants.
Why Are Barrel ITB Upgrades So Popular?
Rennen by JSR Barrel Throttle Bodies provide one of the most exciting induction upgrades available for Porsche engines.
Benefits include:
- Instant throttle response
- Improved airflow efficiency
- Enhanced engine breathing
- Increased power potential
- Exceptional induction sound
