They are. Some people have good luck some don't. I didn't and I followed the TSB to a "T". It seems the sooner you replace them the better off you are. Mine were at 75,ooo and 6 of the 8 broke.

Would love to give up real good advice, seems everytime I get the opportunity to view a 4.6 or 5.4 I walk away thanking God for my little 4.2. Sorry and good luck.
