it's easy to remove the throttle body, but you will still struggle to see where to fit the blanking plate ('coin')
the inlet manifold takes about 30 minutes to remove, due to loads of wiring loom clips underneath, but it's easy to fit the blanking plate with the inlet out of the car.
All the inlet gaskets can be reused, as they are rubber
still use the 'O' ring, then fit the 'coin', then the clip, you might have to fit a washer as well as the 'coin' to ensure a tight fit 🙂
