Not sure. I have the 1.6 gdi engine in mine and it is 11:1 cr. Yours has the 2.0 right? Not sure of the cr on it though or if you have any knock. I only have slight knock/ticking using oem plugs with 87 octane, high map pressures, high load, and at varying rpm. Sometimes you have to know what to listen for and sometimes it is obvious.
