It is overwhelmingly effective compared with OEM
I tried some things other than OEM but it worked best in the range that I can use with my car model.
OEM <PROJECT μEco-Sport, SBSRacing sintered (Cold) << SBSRacing sintered (Warm) <JICO CeramicSinter, RKMega alloy, impression is about.
Although Ziku also works, Mega alloy likes Touch himself, and Mika alloy prefers that Cicum Sinter of Ziku will soon disappear. Considering the low price of Mega alloy, I feel like I do not have to try any more.
