Cook pasta according to package directions until al dente. Drain, rinse under cold water, and set aside.
If using fresh corn, grill or sauté until slightly charred for extra flavor. If using canned or frozen corn, drain well and lightly sauté to enhance flavor.
In a large bowl, whisk together mayonnaise, sour cream, lime juice, garlic, chili powder, smoked paprika, cayenne (if using), salt, and pepper.
Add cooked pasta, corn, cotija cheese, and cilantro. Toss until evenly coated.
Chill in the refrigerator for at least 30 minutes before serving for best flavor.
Garnish with extra cotija, cilantro, lime wedges, and a sprinkle of chili powder.
