Query: Bosch wire set for 2001 Buick Park Ave.

What else can I say, they are BOSCH. Very good quality wire set that will go the distance and provide years of trouble free service. Also, consider changing the three coil packs on 3.8 Buick engines that provide the spark to these wires as precaution to any future problems. I am sure the coils can be found on Amazon and go for the A.C. Delco units as other might be imports and not work well. Good Luck!
