In a small bowl, stir together the lime zest, chili powder, garlic powder, and salt until evenly combined.
In a medium bowl, toss the warm pasta with the avocado oil, lime juice, and half of the spice mixture. Stir well until evenly coated.
Preheat the air fryer to 390˚F (200°F) for 5 minutes.
Add the pasta to the air fryer basket and cook for 8 minutes, tossing every 2–3 minutes and watching carefully to avoid burning, until the pasta is beginning to brown and crisp.
Return the pasta chips to the same medium bowl and toss with the remaining spice mixture until well coated. Let the pasta chips cool slightly, about 5 minutes. The chips will continue to crisp up as they cool.
Serve the pasta chips with guacamole for dipping.
