I removed the big one on the airbox intake, the white one I opened it and covered all the holes with electrical tape and re-installed the two halves of the white silencer and re-installed it. I kept it just because it looks like an old velocity stack and I prefer that the air enters thru this item than the angled corner of the airbox cover.
In racing issues, Living in an island on the caribean gives me constant temperatures and humidity: 87*, 90% humidity and 7 feet above sea level. I guess no altitude corrections are required. In previous experience my times improve by about almost a full second when the same car goes to the states.
I guess I am also an Old head but from Puerto Rico.
