I am in a process of inatalling a paxton novi 1200sl kit, ive recently acquired this kit which came with everything i should need minus the tune and the maf sensor. I have 2 questions that go as fallows ---> 1. with the kit installed which maf sensor do i need to use?(the kit came with 39psi ford racing injectors and the ford racing spark plugs for SS aplication and kennibell boosta pump)2.How do i clean the air filter, the kit was used before and the filter appears to be dirty, with my current K&N cai i just used the k&n refresh kit but i am not sure if i can use same cleaner and oil on the air filter for the supercharger. Any help would be appreciated thank you.
