Volkswagen / Audi spark plug 101905631A F7KPP332U factory-grade efficient combustion quality

This spark plug directly replaces original factory numbers 101905631A and F7KPP332U, with strong universality and compatible with many old-generation Volkswagen and Audi engines. Its core function is to provide stable and efficient ignition; iridium alloy electrode material ensures ignition strength does not decay over long-term use, enabling more complete combustion. Fits Volkswagen models after 2000, such as Passat, Bora, Golf, and also Audi A4, A6, etc. After installation, the most noticeable improvements are steadier idle, no rough acceleration, and slightly improved fuel economy. If you experience cold-start difficulty, acceleration hesitation, or sudden fuel economy drop, the spark plug is likely aging and should be replaced.
