I am intersted in finding cheap upgrades that make real differences.
I removed my secondary air filter, don't know if it improved my gas mileage yet but it sure improve my throttle response and acceleration.
I ran some 0-60 passes. 5spd automatic V6 4DR in overdrive.
Factory primary and secondary filters 8.04 seconds
Factory primary no secondary filter 7.86 seconds impressive
This tank of gas has been getting dogged and still achieved 17.84 mpg. I was just wondering if any other ppl have done and can verify any mods. I have the 4.0 5spd auto, 4DR 4x4, 16" steel wheels. No other real upgrades just some vent visors and a bug flector.
I would like to know if anyone simple replaced the air filter and noticed any improvements.
I would also like to know if anyone replaced their muffler and gained improvements. I am not interested in changing the sound, it will be a by product. I don't want to spend the money making it sound different if that is the only gain.
