Pros

- Four elements means longer runs between cleanings
- The dealer (non-W3) route is the only multi-year term available in this category
Cons
- The lid needs a strap wrench if the O-ring swells in heat — the common knock against it
- Buying the W3 online costs you the labor coverage and two years of parts
- A dead non-W3 listing on Amazon carries a separate 4.1★/88 base — make sure you are reading the live one
