Does anyone know if the MAC cold air kits come pre-oiled, or do you have to oil them before installing them? Also, can you use the same filter charger kit (cleaner and re-oil) as the K&N's? I just bought the MAC fenderwell kit and can't tell if it is oiled or not. I have the K&N filter charger kit from another car that I had, and was wondering if the are all the same. The filter looks very much like a K&N.Thanks.
