Re: #1. There are different part numbers for all the different cars involved and remember there are different fixes as well (some involve replacing just one hose, some more then one hose, some wrapping hoses, etc.). What is your model and production date and I'll try to find out for you. Also what is the p/n of the separator that you got last year?

Re: #2. Thanks for the tips. BTW anything special I need to know to clean an MAF?

Re: #3. Very cool idea. Can't wait to see it!
