Its copper-glass seal bonds the insulator, terminal post, and center electrode together, helping provide the required voltage at the spark gap while maintaining a gas-tight, leak-resistant seal.\u003c\/p\u003e\u003cp\u003eA multi-rib insulator helps reduce the risk of flash-over, while the one-piece terminal post adds strength. The integrated resistor helps reduce radio frequency interference (RFI) and electrode erosion. A cold-formed steel shell features precision-rolled threads for reliable installation.\u003c\/p\u003e\u003cp\u003eThis AUTOLITE 4263 spark plug is listed for select BMW applications, including BMW R100RS models from 1988 through 1995, the 1991 BMW R100, and the 1980 BMW R65.
