Product Overview
Restore the legendary brute force and smooth acceleration of your vintage Kawasaki with the GOOFIT High-Performance Intake Manifold Adapter. Specifically designed for the heavy-hitting GPZ1100 (ZXT10A), KZ1000, and ZX1100 series, this boot is a direct replacement for OEM #16065-1131.
In high-displacement vintage engines, an airtight vacuum seal is the difference between a smooth ride and a frustrating one. Old, hardened boots allow air to leak past the carburetor, causing dangerous lean-run conditions and engine overheating. Our replacement is built from high-quality, fuel-resistant materials to ensure your engine breathes perfectly and delivers "like-new" power.
Product Compatibility
Direct replacement for Kawasaki 1000cc - 1100cc 4-cylinder engines. Please verify your OEM part number before ordering.

- Stable Idle & Throttle Response: Eliminates the phantom air leaks that cause "hanging idles" or engine hesitation during acceleration—common issues in large-displacement Kawasaki inline-fours.
- Fuel & Heat Resistance: Built to withstand the harsh chemicals in modern fuels (including ethanol) and the intense thermal radiation from air-cooled engine blocks.
- Durable & Reliable: Strict quality control ensures that each adapter meets high-standard requirements, providing a long-lasting solution for restoration projects and daily riders alike.
