Yeah I forget most people don't like to do things like this and cam installs in their garage like I do. lol But yeah gear installs at a shop are stupid expensive so best bang for your buck would be cai+tune combo especially if you get a good tune.

This is true, but you'll gain more HP out of the JLT or K&N piping since its wider and less air flow distance. Throwing on a K&N filter is just as pointless.. Gears will wake up the car but you will not gain HP out of it. You'll just get through the gears faster. Personally Id do the CAI+Tuner Package because installing the gears is something I don't recommend doing yourself vs a professional. The CAI package you can do yourself without spending more money to get the gears installed but unless you have the extra dough to spit out either way is a good option.

Both filters are tested to ISO5011 standards by outside labs(in this case Southwest Research Institute in San Antonio, Texas) and Spectre test showed 98%-99% cumulative fractional efficiency, which is the percentage of dust particulates that the filter traps. IIRC filter testing does 5 microns to like 170ish.
I personally think their cai's are pieces of crap, but I haven't had a problem with their filters....yet lol

THAT being said if you increase the tube AND TB/plenum, there is point of diminishing return. you will only gain so much as you increase in size, then you will start to slow down the velocity of the air, which will hinder performance. this is not my opinion, it is facts based on fluid dynamics. it's proportional in terms of volumetric flow rate. given the same volume, if you increase tube size, velocity decreases.
So getting a JLT 4" monstrosity only looks good. and the stock setup is a good CAI as it is. So by putting in a quality K&N filter will be beneficial.
The most effective/efficient setup would be a good filter, 70mm TB/plenum and a good DYNO tune. None of that email canned tune stuff.
OK I'm out lol

Link to said results/reports? Otherwise it's a bunch of mumbo jumbo from someone on a car forum which = useless...no offense.
Do research before throwing out ideas. A larger piping intake tube does nothing since the motor takes in a given volume of air at any given rpm. The stock combo of intake tube and t/b size is set into the cars computer. making the intake tube larger will do nothing for you. the TB then acts as a choke point as the most air you can take in is only the amount the SMALLEST point in the intake tract will allow.

Yea.. If you don't get it tuned properly lol.. It may not give you a ton of HP out of it or feel as noticable as gears but you still gain more then just slapping on a K&N filter, and it's cheaper( vs gear install). Hence it's one of the first stages of modding cars along with the exhaust.. Getting a real CAI vs a short ram CAI (take stock cai with removed airbox/silencer for example), is going to give you some sort of gain over the stock cai with a k&n slapped on it. Removing the silencer box your going to be sucking in heat which is going to hurt him.. its a fact. Normally when you do a CAI intake install normally you consider upgrading the throttle body someday down the road.. I may have not said it earlier on but it kinda makes sense.. enough research for you? -_-

lol you would start **** Buckley.. I said in my post earlier that he wouldn't. Read buddy, read. Bang for your buck is not the phrase to use for the gears package. Your forgetting install. Cheapest place I ever found for gear installs were $175, and that's if you find a mechanic that wants to do it. My point is take that $40 and put it somewhere else if your telling him to slap on a K&N because unless the paper filter is old and dirty as hell then it's pointless aswell. And there is nothing hypocritical about this convo at all dumbass lol...
