zfr5f-11 plugs

[03protege5]

So I recently swapped to the zfr5f-11 long reach plugs and is it possible that I’m burning more gas with these plugs than the not long reach? I feel like my car runs worse on these plugs than the standard ones like I was using before. Previously I had the iridium’s in but not the long reach

Regardless I’m definitely getting more fuel smell while driving around than I was before I made the swap

Thanks
