Just wondering how reliable these are and if anyone has any experience with them. Heard some stories of these leaking on some 55 cars but what about the 63s? Are they worth it?

 

told u i have them . no leaks and my car runs great , especially under tough driving conditions .

prime example ' Track last year in October 55-60 degrees hot lapped 20+ times and the car stayed between a tenth or two at most .

Based on the mods u have done ur pretty much "already dirty " so just do it man lol
