New in the box set of 2 Bosch Super FR 6DC+ spark plugs. Bosch has superceded the old two prong FR6 DDC plugs with this new improved version. These plugs now have a single electrode with a Yttrium center electrode for long life and a V-groove ground electrode. Get improved cold starting and smoother idle/cruise performance along with longer life, all for less than half the cost of the old plugs at the dealer!! These will fit all single spark R850 & R1100 bikes (except R1100S) and the R1200C. |
