I was thinking about getting Steeda 4.6L Underdrive Pulleys (Mid 2001-2004 GT) on my car. however since my car is a DD, I have a few questions.

Would I need to worry about blowing/loosing power on any accessories?

Would this "hurt" my car since its a DD and has around 100k+ clock?

Thank you!

 

I never had an issue on my GT for the 20,000 miles they were on. I'm planing on getting some soon for the snake...
