I have just installed a pb, performance is good.
Overally, as claimed:
1) more pickup power.
2) light brighter.
3) Car felt lighter.
FC, not sure as just installed.
Sorry to tell that I am a bit disappointed with the QC issue raised in this post. But, the seller never claimed that he or she is selling the best product or at least the seller never claimed that his or her product is better than Z*****. So, I am ok with what I have bought as it functions as he or she claimed.
If somebody confidence that his or their product is being copied or imitated, please take out rigid proofs (just some photo does not really convincing) and if u are really confidence, goes by law. Maybe somebody is doing this for the sake of all forumers' good but spamming or threatening other's sale thread is not the proper way of proving that somebody's product is "fake or not ori" (unverified assumption).
Well, since somebody claimed that his or her product is better, convince us with your reliability, high humidity and high temp or even water proof TEST REPORT. I believe forumers have enough intelligence to intepret them, this would be much more better than what somebody is doing now, at least acts more pro.

I'm totally agreed what he said. Show us everything in Test Report. Atleast a water proof test report cos this the main subject u all arguing.
