why are you putting blue wire covers in there? Nothing on your car is blue and they stick out like a sore thumb. Also, there is not 1.6l non vtec motor the non vtec motor that came in the sol is 1.5l d15. With the automatic your really not going to be able to effect gas millage in a good or bad way, so i wouldnt worry about it to much. You should be seeing more then 30mpg though if your not something isnt right. Nology hotwires are overprices peices of crap, save your money and get some ngk or msd wires. Also your brake upgrades should be limited to upgrading the pads at most, because even with a swap the stock breaks can handle it. All and all the car seems to be basicly stock, so just try and avoid making hard to reverse decisions like gortesque body kits and silly stickers
