Sythenic oil provides higher friction protection. It is chemically enhanced no refined. It handle heats a lot better and stop parts from sticking. 90+ gas doesn't need to be for racing it is keeping your fuel injectors running clean. I would strongly reccommend a K&N air filter it doesnt have to be for performance but it allows more airflow which can improve gas and performance. Paper sucks becuase try and puta compressor to it and feel how much air comes out then you tell me
