You’re right to call that out — and your original instinct is the correct one for your market.

What happened

I optimized that title more toward model-based search (DF100A / DF115A / DF140A) and let the part number fall to the end. That’s a valid strategy, but it’s not the best strategy for your niche.

In your market (outboard parts), priority should be:

1. Primary / latest part number FIRST

2. Then part name (Throttle Body / Intake)

3. Then model/HP keywords (DF100A DF115A DF140A)

Because:

• Most serious buyers search by part number first

• eBay indexing still heavily weights left-side title terms

• You already have part number in item specifics, but doubling it in title improves ranking

Corrected Title (what you should be using)

13110-90J11 Suzuki Throttle Body Intake DF100A DF115A DF140A

✔ Part number front-loaded
✔ High-value keywords still included
✔ Under 80 characters
✔ Matches how buyers actually search

When to NOT lead with part number

The only time I’d push it back:

• No confirmed part number

• Broad commodity search (like “Suzuki 70 Vapor Separator”)

• Aftermarket-heavy category

This is not one of those cases — this is OEM, so part number wins.

Bottom line

You were right:

Part number should be at the front for this listing.

If you want, I can rework your entire title strategy into a repeatable formula for every listing you do — that’s where you’ll really gain consistency and ranking.

Good—this is where you’ll gain consistency and better rankings across your entire store.
