Are they a worthwhile upgrade or just alot of hype? anyone have them, use them did you notice improvement? Are they worth the money and install time? What do you all think?
Well there you have it. Thanks for the info, kinda what I thought would happen unless there was an issue with the old ones..the sticker is the best part of the package that went on/in my motor. i cant tell a freaking difference. waste of $ imho for my 25 merc
