the only thing i can really think of is its much much less restrictive, but i'm surpirsed the heat from the engine doesn't offset this

Unfortunately there is no room for a cold air unit of course that would be ideal. The increase is partly suction and partly air temp.
We were able to measure the amount of vacuum suction in stock form and compare that to the vacuum suction after the intake install.
The stock box measured as 3%.
Britalman measured at 7%.
A cold air intake would be less suction but colder air. These dyno runs are proof that a good heat shield and an increase in suction are the keys to producing some good HP numbers.
