Could be. I replaced my 02 sensors, MAF, spark plugs, and ignition coils. I never did an official mpg calculations (not going by the cluster), but I would say I jumped from maybe ~19mpg (the initial reason I changed everything) to ~25mpg (and I like to ). The ignition coils I did maybe 2 months ago, as I had 1 bad coil. So, I figured just upgrade tham all at once to the R version. But brand new R versions are supposed to grant you greater mpg.
