Product Overview
Restore the screaming performance of your inline-four "Baby FZR" with the GOOFIT Precision Intake Manifold. Specifically designed for the 1989-1994 Yamaha FZR250 (3LN Series), this part is a direct replacement for OEM #3LN-13586-00.
The FZR250 is famous for its ultra-high RPM engine. For such a high-revving machine, the slightest vacuum leak in the intake boot can lead to catastrophic engine leaning or erratic idling. Our manifolds are engineered from high-strength, heat-resistant materials that can withstand the extreme thermal environment of this 4-cylinder engine, ensuring a perfect seal and a long-lasting riding experience.
Product Compatibility
Direct replacement for the Yamaha 250cc Inline-Four "Exup" models. Please verify your model's 3LN chassis prefix.

Key Features
- Built for High-RPM Stability: Specially formulated to withstand the high-temperature and high-pressure environment of the FZR’s 20,000 RPM-capable engine block. It effectively resists aging and deformation under intense thermal stress.
- Corrosion-Resistant Material: Made of premium quality materials that resist the corrosive effects of modern ethanol-blended fuels, preventing the internal degradation that causes air leaks and poor fuel atomization.
- Precision Vacuum Integrity: Our strict manufacturing process ensures an exact fit to the cylinder head ports. A perfect airtight seal is critical for this model to prevent "hanging idles" and ensure smooth power delivery across the entire rev range.
- Prolonged Service Life: Engineered to resist the dry-rotting and cracking common in 30-year-old factory rubber. These manifolds are built for long-term durability, providing a reliable solution for restoration projects.
- Direct "Plug-and-Play" Fit: Strictly matches the 3LN-13586-00 dimensions, ensuring the carburetors seat perfectly in the chassis for proper airbox alignment.
