I have 2007 Civic coupe LX 1.8 not sure of gen, car runs great. I just want to make it run better all parts on it now are original. I would like to start with performance before looks, I plan to keep this car. I have had this car for 5 yrs now no major issues. I just want to know where to start and what parts are quality. Not trying to race just want to get the best ride I can out of it. Please assist with recommendations. On where to begin.
