Finally, we made it to our day of testing! We had previously confirmed fitment and made a few minor adjustments to some external end-tank features to improve coolant flow and ease of installation. A member of E90post was kind enough to lend us his vehicle for this round of testing. This 2007 sedan was equipped with a manual transmission, JB4 software and an intake. This vehicle would be ideal for collecting testing data, we have found that the “Average” E9X owner has similar modifications.
