Re: Insulated Air Box and Intake

For naturally aspirated engines, the stock intake on these modern vehicles is 99% able to develop rated HP. What you might get is 'recovered' HP from a true CAI for horses the stock doesn't quite deliver. It will be small, very small. And not during traffic, either. Engine bay temps saturate the intake until a strong, steady airflow is developed.

A heat shield surround would probably do the most good in keeping ambient and engine heat away from the intake tube and slow the saturation effect.

The real improvement is in throttle response and maybe fuel mileage. Watch your tach and see if you run at lower engine revs for a known highway speed. Most helpful in hot weather when the greatest HP loss occurs. Small gains but more fun from the pedal...
