I am looking into buying the PTuning ODB for an NA 2005 S2000 but need a measurement between the bottom of the value cover and the top portion of the stock airbox. I need a value less than 4 inches to have adequate clearance for an oil pressure sensor and the other lines attached to the block. It would be greatly appreciated if someone got the measurement for me since I will not be able to check my own car for a while.

For reference refer to the green line in the picture below. I need that length. Thanks!
