sure my philosophy is simple ...what makes the engine run is fuel air and spark..anything u can do to make it breath better or clean your fuel injectors once in a while, clean or change out spark plugs or if u are super motto u can get headers and exhaust..but its a family car so don't get carried away...its simple way to make sure u car runs at its best... some people don't care about things like that ..(no one in this forum).. so when the car starts acting up they loose it....my car is a smooth running beast no problems thank god and preventive maintenance..."my soul smiles when i drive"
