Choosing an intake for your Yamaha GP1800 SVHO
Start with your exact model, year and engine. The GT40 Yamaha cold-air intake kit is for listed supercharged 1.8L SHO/SVHO applications. Confirm the intake connection and clearance on your ski before ordering.
GP1800 and GP1800R SVHO owners comparing an intake kit
Compare the options
| Option | Best for | Before ordering | Notes |
|---|---|---|---|
| GP1800 / GP1800R SVHO | Selecting a kit for your GP model | Model year and intake layout | Check the product listing against your exact ski. GP intake families differ by generation; send photos if the connection or clearance is unclear. |
| FX / FZR / FZS SHO/SVHO | Checking a different Yamaha hull family | Model, year and engine | Use the application listed for your ski. A shared SHO/SVHO engine label alone does not confirm the intake layout. |
| 1.9L HO or TR-1 | Ruling out the wrong intake family | Not compatible with this kit | The GT40 Yamaha 1.8L SHO/SVHO intake kit does not fit these naturally aspirated platforms. |
Identify the ski before choosing the kit
Use the full model name, model year and engine designation when checking the product page. Keep GP1800, GP1800R, GP, FX, FZR and FZS applications separate until the exact listing has been matched to your ski.
- Confirm that your ski has the listed supercharged 1.8L SHO/SVHO engine.
- Compare the intake connection, diameter and available clearance with the product information.
- If your existing intake has been changed, include photos when asking for a fitment check.
What to check on the intake product page
Review the stated application, included components and any additional parts or installation information before ordering. If a detail you need is missing, ask GT40 to confirm it for your model and year.
Keep other upgrades separate
Choosing an intake does not confirm that an intercooler, exhaust part or package fits the same ski. Check each product separately and use its current availability and application information when planning the work.
Get help with the match
Send support@gt40marine.com your model, year, engine designation and clear photos of the current intake connection. Include the product link you are considering so GT40 can review the same kit with you.
Common questions
Does an SVHO intake fit every GP1800 model?
Check the exact model year and intake layout before ordering. The GT40 fitment information separates GP generations and calls for confirmation of the connection on your ski.
Can I use this 1.8L kit on a 1.9L HO or TR-1 Yamaha?
No. The GT40 Yamaha 1.8L SHO/SVHO cold-air intake kit is not compatible with the naturally aspirated 1.9L HO or TR-1 platforms.
What should I send for an intake fitment check?
Send the model, year, engine designation, product link and photos of the existing intake connection. Mention any changes to the current intake setup.
