Bosch Spark Plug - WR7DC
During operation, spark plugs are subjected to wear and fouling, so they should be replaced during intervals to ensure optimum engine performance. Worn or corroded spark plugs are no longer capable of igniting the fuel properly and can cut down on your fuel economy. An increasing number of automotive manufacturers install Bosch spark plugs in their vehicles. Bosch OE Specialty Spark Plugs feature the same fit, form, and function as the OE spark plugs currently installed on your vehicle. They ensure optimal performance and a long-lasting spark plug life at a price tag that will suit your pocketbook.

A standard replacement product for the requirement. The similar application Bosch product (platinum electrode) WR7DP tested faulty for 3 out of 6 units, purchased for longer service life, and were not installed (a refund was issued). These standard spark plugs were installed instead.

LPG burning engines are sensitive to out of tune or weak ignition systems that may not be performing at their optimum to provide a strong reliable spark (and/or valve gapping / timing and incorrect fuel/air mixtures). In such instances there is increased probability of backfiring that can do damage to other ... MoreA standard replacement product for the requirement.
