Hmmm. OK. Fully 'whoa'd'. I run 93 fuel (yes I have a tune for it). So what your saying is 'try a set' and see. FYI: currently, I replace my plugs A104's ~3-5K (cause that was what I read somewhere). There always 'pristine' which made my think I was replacing them too often.
P.S. your running A103 or AR103?
Steeda SRI w/CAI intake. Trubendz SS 2.5" . FR Susp/Struts. Tune by Tom (FocusPower). Rota Grids. SAP rear spoiler. Custom front air dam, rocker panel bits and Rear valance.
