I think what most of us forget these days is this. The engineers are doing a great job of designing most systems and they are balanced to work with the computer system on board. Mods that affect air flow , cooling, and other things such as that will generally cause more harm than good. Yea back in the day when the engine was not managed with a computer we could do lots of things and found reasons in our minds that it was better. I just don't think we can make there mods now without screwing someother things up - just my opinion
Yea i can definatley go along with that. i know with all my older vehicles i was always adding stuff. but first it was stuff that i knew would give me gains in power and torque. like pistons,heads carbs and so on. then i added exaust for breathing reasons.never did i buy k&n filter. the only reason i had it with the jeep is because i bought it that way. one thing i do know is with the added vacuume and crap i put the 73 chevy 4x4 through im glad i didn't. it would do nothing but suck in crap. as for the monte carlo i couldn't see that tiny bit of performance against the true gains my neighbor,his sons, and i got out of it with what we done.
there are way better mods you can do than a crap sucking airfilter and such. like save your money and have a stroker built, or buy a good 4.2 and build it up and do a 4.0 head conversion. that is if your state allows it as far as emissions. those 2 options will give you true gains.
