Stock Intake vs Flashark Intake
Upgrade your engine with the Flashark 4" Cold Air Intake and feel the difference immediately. Compared to the stock intake, here’s what you can expect:
- Airflow: The stock intake restricts airflow, limiting engine potential. Flashark’s design allows maximum airflow, feeding your Vortec engine more cold, oxygen-rich air.
- Throttle Response: Stock systems often feel sluggish, especially at low and mid RPM. Flashark improves throttle response, giving you quicker, smoother acceleration.
- Sound: Stock intake is quiet but uninspiring. The Flashark intake produces a deeper, more aggressive intake sound that enhances the driving experience.
- Maintenance & Cost: Stock filters are disposable and need frequent replacement. Flashark’s high-quality cone filter is washable and reusable, saving you money over time.
Experience more power, torque, and excitement with every drive—your GM truck or SUV will feel transformed.
Washable, Reusable Filter
The Flashark cold air intake isn’t just about performance—it’s designed for long-term convenience and savings.
- Washable Filter: The high-quality cone air filter can be cleaned and reused, eliminating frequent replacements.
- Cost-Effective: Save money on disposable filters while maintaining peak engine performance.
- Long-Lasting Performance: Designed to last the life of your vehicle with proper care.
- Maintenance Interval: Simply clean your filter every 10,000–15,000 miles to keep airflow and performance at their best.
With easy maintenance and reusable components, the Flashark intake ensures your engine keeps performing at its peak while reducing ongoing costs.
