I've been running with the ESIS for a while now and definitly think there's a noticible incremental improvement. now I want to work with someone local to see if they notice a difference as well.
I'll guide the tester through installing the ESIS him/herself (I don't want to touch your car and will not be responsible for any damage). the tester will need to leave thier stock airbox plus a $20 deposit for the hose and my time (I need to make sure and get these items back to continue testing ). the tester would get the ESIS for one week and be asked for comments on it as well as comments on the stock system after having driving with the reverted airbox for another week.
