3" High-Performance Intake Filter Kit – Sea-Doo 1503cc & 1603cc 2005+

Description

The 3-inch high-performance intake filter kit for Sea-Doo is designed to replace the original airbox on 1503cc and 1603cc supercharged Sea-Doo personal watercraft. This kit continuously supplies fresh air to the supercharger via a large-volume intake duct connected directly to the supercharger through a 3" adapter. The integrated high-filtration K&N-type filter ensures maximum airflow while protecting the engine from impurities, resulting in improved acceleration and quicker throttle response. Installation is simple and removal is quick for easy engine access during servicing.

Why Install a High-Performance Intake Filter Kit?

The original airbox on supercharged Sea-Doos is designed to meet standard requirements, but it limits airflow to the supercharger. By replacing it with a large-volume direct intake kit, you allow the engine to breathe freely and fully exploit the supercharger's potential.

• Improved acceleration and quicker throttle response
• Optimized fresh air supply for the supercharger
• Reduced engine resonance thanks to the rubber tube
• Easier engine access during servicing (quick removal)
• Washable and reusable filter: economical maintenance in the long run

This kit is ideal for riders looking to improve the performance of their supercharged Sea-Doo without invasive engine modification. It is recommended to pair it with a complete supercharger overhaul for optimal results.
