K&N High Flow Air Filter for Yamaha YZF R1 (2007-2008)- YA-1007

K&N High-Flow Air Filter | Yamaha YZF-R1 (YA-1007)

The YA-1007 is the high-performance intake upgrade for the "Generation 4" Yamaha R1. This specific model (2007–2008) was a landmark for Yamaha, introducing the 16-valve engine (moving away from the 5-valve design) and the revolutionary YCC-I (Yamaha Chip Controlled Intake) variable-length velocity stacks. The YA-1007 is engineered to support this high-tech intake system by providing the massive air volume it demands.

Key Features

• Variable Intake Optimization: Engineered to provide up to 50% more airflow than standard paper filters. This ensures that when the YCC-I funnels lift at high RPM, the engine isn't restricted, allowing for maximum top-end horsepower.

• Superior Filtration: Features K&N’s signature multi-layered oiled cotton gauze media, trapping up to 99% of contaminants while maintaining the high air velocity required by the large 45mm throttle bodies.

• Washable & Reusable: A permanent "Lifetime" upgrade. Simply wash, re-oil, and reinstall the filter. It typically only needs cleaning every 80,000 km (50,000 miles) under normal highway conditions.

   

• Direct Drop-In Fit: Precision-molded for a perfect, airtight seal in the factory airbox. It replaces Yamaha OEM part number 4C8-14451-00-00.

• Increased Intake Howl: Provides a more aggressive and visceral intake sound as the engine climbs toward its 13,750 RPM redline.

Why Choose K&N for your 2007–2008 R1?

The 4C8-generation R1 is known for its incredible top-end rush. Because this engine uses variable intake stacks, it is extremely sensitive to intake pressure. The YA-1007 "uncorks" the airbox, providing a sharper throttle snap and ensuring the engine breathes at 100% efficiency throughout the entire powerband. It is a vital modification for riders looking to maximize the performance of this 16-valve screaming inline-four.
