So a few months back, I traded for an evo. It came with some uninstalled upgrades, one of which was a supposed set of Denso 720s.

Now, I'm pretty damn sure they arent denso's, as they look like FIC style ball/disc to me.

Numbers on them are scratched in the side, just like an old set of FIC 650s I bought for my dsm back when.

The numbers on them are
2475 / 08175
14375 / 08175
5875/ 08175
13675 / 08175

First number doesnt match on any of them, but hte last set is the same on all 4. wtf are they? Any help is appreciated.

Wondering if they are worth running, maybe get them cleaned/flowed or just toss them and buy 4 new ones.

 

Definately look like FIC's to me. Hard to say what size they are though.
