Spark plugs for minor mods?
i'm running JWT pop charger, HFC, y-pipe and my car isn't getting good mileage. After many searches I decided it's best to replace the spark plugs. Can I use NGK Iridium (LFR5AIX11) or the OEM Platinum plugs? My car getting 14.7 mpg and 17 mph which i think is low.

How many miles do you have on your car?

my average mpg under normal conditions is 26-29 mpg on the highway, depending on how heavy my foot is that day, and i get between 18-20 in town. if you are getting low mileage i would def start with the spark plugs. 45k on the odo.
