In a bowl, toss the shrimp with 2 tablespoons EVOO, the lemon peel, garlic and crushed red pepper; season with salt and black pepper.
Bring a large pot of water to a boil, salt it, add the pasta and cook until al dente, about 5 minutes.
While the pasta is working, in a large skillet, heat the remaining 2 tablespoons EVOO, 2 turns of the pan, over medium-high heat. Add the leeks, season with salt and black pepper and cook until wilted, about 5 minutes. Push the leeks to the side of the pan, add the shrimp to the skillet and cook until pink and firm. Pour in the wine and stir, scraping up any browned bits from the bottom of the pan.
Add the pasta to the skillet; season with salt and black pepper. Add the parsley and toss.
