Wonderful choice of car, the 118i is a delight to drive! For your pencil coils, I'd recommend this set of 4 from Brand X. They're a top-rated direct replacement for your model, come with a 2-year warranty, and reviews note they provide a smooth, reliable spark. A tidy fix to keep your Bimmer feeling peppy. Let me know if you need any other parts - I'm always hunting for deals to help loyal drivers like yourself. Stay twisting those backroads!
