Let me guess, masters in electronics, mechanics, aeronautics and always being smarter than everyone else? Guess what, you are not the only engineer on this website.
It's typical of you to take a position and cherry pick the questions that you answer and expect to convince us that you are the only one who is always right on all of the subjects.
Btw, the only mod I've seen you mention is the installation of the $600 Alpine Radio in your Ranger which sounded "screechy". Have you tried a K&N Filter?
Btw, buying a K&N saves me from buying 5 or 6 paper filters over the life of my cars, so it saves cash in filters.
If I was an OE I might argue that it''s better to buy new filters from the Factory and not from K&N.

You are correct; aftermarket CAIs do very little, if anything, to increase power or fuel economy.
It's a common misconception that floats around and refuses to die.

What DOES increase power, and in certain cases fuel economy also, is the TUNE that goes with the CAI.
Alot of new people to the pony car scene always appear to fall for the misconception that the CAI itself gives power and completely disregard the TUNE that comes with the CAI.

There are CAIs that are advertised as increasing power of any significance without a tune; for those ads, I am with you; they are complete BS.

He is an intellectual snob and has no priority in developing any meaningful social interaction. All he cares about is shoving his knowledge in everyone's face to make himself feel proud in his belief that he thinks he knows more than everyone else.

The ignore button is a nifty little weapon; once enough people has used it on him and he is talking only to air, he will move on and become someone else' problem.

And yes, he does get butt hurt when you rebut him and give him strong evidence that is contrary to what he posits.

Many of the CAI-obsessed people here are anti K&N filters because of the oil.

I seriously doubt it improved your MPG....paper filters flow better over the life of it, as it turns out. The gains you are seeing are from the tune.

Really? Are you an "engineer" also?

cruisin5268d

No, and yes. That has nothing to do with my comments though. What I am is someone that doesn't have to follow the herd and can think for himself. I look at all the information that I can and figure things out for myself.

For what it is worth, I have owned K&N filters in the past and they make a good product. But they don't give you magic MPG.

Well I am strictly going by my results with my cars and not "what theoretically should occur"

Other people's results may vary but I saw in increase in mpg with only a drop in filter on one car and a tuneless CAI on the other with no other mods.

Not trying to stir the pot further, but he and jz are correct. The tune gives the power increase, and for me, it gave me a fraction of an MPG more when I did my hand calculations of my own car.

Speaking from my own experience, I bought an AirRaid CAI and BAMA tune.
Upon opening the AirRaid box, and reading the installation instructions, I saw that the AirRaid can be used with or without a tune.
To test this, I installed the AirRaid but didn't upload the tune. Granted, this is all only from my butt dyno, but the AirRaid by itself didn't register anything different than with the stock air intake.
Then, I uploaded the BAMA tune and my car really came to life.

From a more empirical standpoint; a few of my friends did the same thing; ran bone-stock cars with only the aftermarket CAI using stock tune, and then uploading the tune afterwards.
On the dyno, they saw anywhere from 10-15 more RWHP on the aftermarket tune and no RWHP increase with just the CAI and stock tune.

So, this "tune" thing that you speak of changes engine parameters and alters how the engine performs is what actually adds power....and not a hollow plastic tube that feeds into a throttle body that isn't changed? Tell me it isn't so!
