I'm not a fan of K&N filters either...especially after seeing oil analysis comparisons...but your Toyota guy must be unaware that the TRD intake uses an oiled air filter.

Both of these statements are false. The lower the temperature of the air, the less moisture it can contain. This is why the high mountains and polar regions of the earth are also the most arid. The cold air cannot hold moisture as well as warm air. This is also why we experience rain...as warm, humid air rises, it cools and the water vapor condenses into rain drops.

The oxygen content of cold and warm air is exactly the same...roughly 21%. However, cold air is more dense, so a given volume of cold air will contain more oxygen molecules than warm air. The oxygen content doesn't change with temperature...only the density.

Thank you Dallas Rains! But we are talking about a smaller amount of cold air witch does in fact contain more oxygen than the same volume of warm air. I learned all about cumulus and rain in grade school. Your lessons on rain are contradicted by the last two lines in your post Tex. Witch one do you wanna talk about?

Jesus - we're really parshing words here... he had the essence right.

The amount of oxygen is greater in denser (colder) air - just not the percentage. Therefore the oxygen content is higher.

Anyway - cold air works for the same reasons forced induction works. Denser air creats more pressure in the cylinders, and more power.

Yes...but your first post said content and didn't mention volume.

The last two lines of my post deal with the oxygen content of air with respect to temperature and have nothing to do with moisture or precipitation. Unless you know of a new addendum to the laws of physics that somehow relates gaseous oxygen content to the capability of said gas to contain water vapor, there is no contradiction in my statement.

Then lets change a few words and end it here gentlemen.

....and I ment nothing by the "Dallas Rains" crack, we actually have a Dallas Rains weatherman here in LA.

Just goes to show ya that Toyota driver's are Indeed educated. We go from talking cai's to the laws of physics. What and extraoridinary bunch of chaps !!! lol

if we throw in someone comparing something or someone else to nazi's we have your average internet forum.

You're flirting with Godwin's law there mister!

x2, The oil from the K&N will gum up the MAF sensor.

Actually, I was referring to engine oil analysis that showed increased particulates due to inadequate air filtration. However, I've also had to replace two MAF sensors due to oil fouling from K&N filters in the past. I'll never use one again.

Fool me once, shame on you. Fool me twice, shame on me!

That is one of the reasons why I went with the Volant.

Type and price would be nice.
Thanks

Im selling mine for $220 shipped from Los Angeles. Let me know. Its in mint condition and has less than 100 miles on it.

Wow imagine that. Oil free here. AFE
