What BuckParts verified

BuckParts lists EDR4RXD1 for WRX735SDHZ in compatibility data. Retailer-path checks are separate—an eligible verified link appears only when current gates allow it.

What’s still unknown

This is a base-model example, not a check for your appliance. Confirm the full model on the rating plate—do not rely on the model row alone for fit.

A fresh fit-evidence review date is not re-established here. Suffix-wide coverage and current retailer availability are not asserted on this page.

UNKNOWN means UNKNOWN

Missing evidence stays missing—we do not convert unknown into a guessed fit or a disguised buying link.

Where to buy

Buying comes after the fit check

When a BuckParts Verified Link appears, we checked that retailer product page against the part number on that page—not every result includes a way to buy.
