help? I was told that by replacing my 2000 nissan 1.4L ex stock air filters and rims to cold air intake and rim 15 would improve its fuel efficiency and performance is this true? what air filter and rims should I buy thanks
A cone-type air intake will increase your engine's performance BUT your fuel milage will decrease if you want to take advantage of the increase in engine power.
Increasing your wheel size will also decrease fuel milage (I assume your stock rims are 14s and you are changing them to 15s).
