I just put on BWD's. I guess that's the OEM. Advance Auto has em for $40. They were also briefly on Checker's website for $25 but I waited too long and they back to $80. Just google the BWD part# E427.
I had the dreaded P0171 code and the car was hesitating from a stop. Turned out to be the air hose. Like others, there was a rip in the soft rubber accordian area. It was almost ripped in half by the time I got it removed. $60 from the dealer in AZ. Code is cleared and runnin smooth. (wiggle)
I too need to replace a front caliper wheel cylinder boot on my '03 P5. I didn't see one on Amazon, and on Rockauto.com I only saw a rear. Were you able to find one other than the $50 "kit"? And can this be replaced w/out taking apart the whole caliper? It looks like you should be able to...
Anyone know where to get the rubber seal that the piston goes into? Mine is torn. Dealer wants $70 for a "kit" which is just a bag of rubber seals & boots.
