Corksport SRI and check engine light

[vdsracing]

I've tried both Denso IK20 and NGK IFR5E11 on my zy-ve.
They are both ok,not a big difference from stock but I can feel little less power at low rpm and a bit more power at high rpm.
Between these two,I would chose the IK20 but I'm judging according to the greek climate,gas quality etc.
