Bosch OE Fine Wire Spark Plugs

Bosch OE Fine Wire Spark Plugs, including Double Iridium, Double Platinum and Platinum spark plugs, are built around OE technology, have an original equipment specific design and are manufactured to be OE equivalent replacements. As direct injection continues to grow across all makes (Domestic, Asian and European vehicles), and as ignition systems continue to increase in voltage output, things like advanced ceramic technology, spark position and correct gap are more critical than ever. Recognizing this, Bosch created these OE equivalent spark plugs for the aftermarket.
