Power duct install
I just installed a Breathless Performance power duct and MAF ends on my 2000 Hardtop. I have the Donaldson filter also installed and mounted on the grommets. I noticed that the air duct sits up higher over the radiator than the stock unit did. The hood closes OK, but I am sure it is touching the duct. I am worried that the hood might crack due to the duct height. Anyone had experiance with this?

Re: Power duct install (halp)
By loosening the clamps between the MAF, duct, and connection to the TB you can move and slide the duct fore/aft which will help you get it to the lowest point possible over the top of the radiator shroud. Don't worry about a small rub on the liner as long as the hood closes and the edges of the front of the hood and the top of the facia are even. :cheers:

How are the MAF ends working out? Few people can run them susfully on your model C5 (without other tuning tools, maft and such).. they generally cause 99+s to run lean and spark-knock.

MAF ends seem fine. I could notice a difference in performance when I installed them and the power duct. I have only put about 100 miles on since the install.

Re: Power duct install (halp)
I have a 2000 convertible with exactly the same setup -- the BPP MAF ends are the one's with the "airfoils," but also have the Donaldson and Power Duct.
c4c5specialist has Tech II checked mine twice, and my fuel trims are +/- 3% and +/-1.5% to the ideal A/F ratio.
The trick is to get the new calibration flashed to your PCM from the dealer -- it's out on the dealer CD and addresses knock and pinging at higher RPM and full throttle.
If you have a 2000, they just upgraded it again recently.
Do it! :smash:
