2005 4x4 tacoma, V6, stock except a K&N intake and rear springs.
I frequently tow a travel trailer with it, about 4500 pounds.
I put the K&N in mostly to improve fuel economy and it worked well adding almost 2 mpg. It may have added more power and more towing power, but it may be my imagination due to the increased sound.
The kid in me would love to make my truck sound more bas @ss, but the responsible adult in me says that is really not a priority. If I were to do it, it would be for fuel economy and/or better power/towing power.
I came across a guy at a campground recently that had a cherry bomb exhaust in his taco with stock intake. he said it made a difference in tow power and fuel economy, and it sounded bad @ss (even at idle), which is what got me interested in it.
Thanks for any opinions, thoughts, or anything. I'm just starting my research so anything helps.
