Product Overview
Restore a secure and properly sealed connection between the throttle body and engine with this replacement intake manifold, designed for compatible Yamaha Fazer 250, XTZ250 Lander, XTZ250 Ténéré, and YBR250 motorcycles.
This intake manifold replaces an original unit that has become cracked, hardened, loose, distorted, or difficult to seal after prolonged exposure to engine heat, vibration, fuel vapor, and everyday riding conditions.
A damaged intake manifold may allow unmetered air to enter the engine, potentially contributing to unstable idle, difficult starting, hesitation, surging, inconsistent throttle response, or a lean-running condition.
Designed as a replacement for Yamaha OEM 1S4-E3585-00, this manifold features an approximately 41 mm inner opening and an OEM-style throttle-body-to-engine configuration.
Product Compatibility
| Brand | Model | Model / Platform | Year Range | Fitment Notes |
|---|---|---|---|---|
| Yamaha | Fazer 250 | YS250 | 2005–2011 | Verify regional model and OEM number |
| Yamaha | Fazer 250 | YS250 / Brazilian market | 2007–2015 | Yamaha OEM catalog coverage |
| Yamaha | Lander 250 | XTZ250 | 2006–2020 | Primary aftermarket fitment range |
| Yamaha | Ténéré 250 | XTZ250 | 2011–2019 | Confirm OEM number and manifold shape |
| Yamaha | YBR250 | YBR250 | 2007–2011 | OEM intake diagrams use 1S4-E3585-00 |
Yamaha’s official Brazilian parts catalog identifies 1S4E35850000 as the intake manifold for Fazer 250 and Lander 250 applications. The same OEM number is also listed in Yamaha YBR250 intake diagrams.
Exact production years vary by sales market. For example, aftermarket fitment references commonly list YS250 Fazer from 2005–2011 and XTZ250 Lander from 2006–2020, while Yamaha Brazil lists the same OEM manifold on Fazer 250 models from 2007–2015 and Lander 250 models beyond 2020.
For this reason, the OEM number and physical configuration should be used as the final fitment references.

Measurement Note: The supplied 67 mm measurement should not be described as an “installation-hole diameter” unless confirmed by the product drawing. It is more likely a mounting-hole distance, flange measurement, or another installation reference.
Compare the exact measurement points shown in the product images with your original manifold before ordering.

Fitment FAQ
Will this part fit my specific model and year?
This intake manifold is commonly listed for compatible:
2005–2011 Yamaha YS250 Fazer
2006–2020 Yamaha XTZ250 Lander
2011–2019 Yamaha XTZ250 Ténéré
2007–2011 Yamaha YBR250
Yamaha’s official parts catalog also confirms OEM 1S4E35850000 on Fazer 250 and Lander 250 applications, although the exact production ranges differ by market.
Your original manifold should use OEM 1S4-E3585-00 and match the opening, mounting configuration, intake angle, and overall shape shown in the product images.
Do I need to match the OEM part number?
Yes. Matching the OEM number is one of the most reliable ways to confirm compatibility.
This intake manifold replaces:
1S4-E3585-00
1S4E35850000
1S4-E3585-00-00
These are different formatting versions of the same Yamaha reference.
If your original manifold or Yamaha parts diagram shows a different number, do not assume compatibility based only on the engine displacement or model family.
What models or situations does this part not fit?
This intake manifold is not confirmed for:
Yamaha FZ25 models unless OEM 1S4-E3585-00 is independently verified
Yamaha XT250 models using OEM 5XT-13585-00
Yamaha WR250 or YZ250 models
Motorcycles using a different intake-manifold OEM number
Models with a different throttle-body opening
Applications with different mounting-hole positions
Motorcycles fitted with modified throttle bodies
Engine-swapped or heavily modified motorcycles
Applications where the original manifold has a different sensor or vacuum-port configuration
Carbureted motorcycles requiring a different carburetor intake boot
For example, Yamaha XT250 parts diagrams use 5XT-13585-00, not the 1S4 manifold offered here.
What should I check before ordering?
Before ordering, confirm:
Yamaha model and complete model name
Exact production year
YS250, XTZ250, or YBR250 model designation
Regional-market configuration
OEM number 1S4-E3585-00
Approximately 41 mm / 1.61 in inner diameter
Listed 67 mm / 2.64 in mounting measurement
Exact measurement locations shown in the product images
Throttle-body-side opening
Engine-side mounting flange
Mounting-hole locations
Intake angle and orientation
Vacuum or sensor ports
O-ring or gasket arrangement
Product photos compared with the original part
Also inspect the throttle body, O-ring, clamps, vacuum hoses, injector connections, sensors, airbox duct, and surrounding intake components for additional leaks or deterioration.
