Yamaji also advises checking parts around the turbo carefully. Heat shielding surrounds the exhaust manifold, and even the hose in the piping between turbo and intercooler is wrapped in insulation. Exhaust leaks, particularly at the manifold, sharply reduce power.
Minor dents in the exhaust apparently have less effect. The airflow meter and air filter also matter: clean them whenever needed. These are straightforward maintenance jobs worth doing regularly...

Clean the airflow meter regularly: a quick spray
Blow dust out of a mesh air filter! Its coarse mesh can be cleaned by blowing air from the inside outward with an air gun. Even this simple job improves intake efficiency.
Cleaning the airflow meter matters too. The article suggests washing dirt from its wire with parts cleaner.
Dedicated cleaners are sold for cotton filters, but...
Clean a cotton air filter with kerosene!

Cracks occur at the collector
Manifolds usually crack where the four runners merge rather than at the engine flange. There is little preventative maintenance, so buying a reputable HKS or Trust manifold can reduce concern about cracking.
