The components are made with high-grade materials — copper windings and high-temperature epoxy in the coils, and laser-welded iridium\/platinum tips in the plugs — to deliver stable high-voltage output, long service life and consistent firing over time. The kit is intended as a direct replacement for part numbers such as 06E905115E and UF529, fitting popular 2.0 and 2.0T engines in Audi A4, A6, TT and multiple Volkswagen models like CC, Passat and GTI within the listed years.\u003c\/p\u003e\n\n\u003ch3\u003eHow will this kit affect engine starting and idling?\u003c\/h3\u003e\n\u003cp\u003eReplacing worn coils and plugs typically brings back crisp starts and steadier idle by restoring full spark energy and consistent ignition timing.
