The Catch

Deal-breaker: a glow plug may arrive damaged (as reported in at least one SKU review).

Deal-breaker: connector type can vary; mismatched plug connectors may prevent proper installation without modification.

Deal-breaker: gasket packaging may be scratched or torn, risking gasket integrity during replacement.

Deal-breaker: only a single mesh filter is included; some users expect an insertion tool or additional filters.

Trade-off: compatibility may require double-checking plug/connector design for your exact heater model.
