Long story short, this guy measured the temp and at speed (not sitting on a dyno) the temps are about the same.
Now, had he measured on very hot days, I bet that the CAI may actually have shown a higher temp than the pop Charger given the heat coming off of the pavement.
So, IMHO, modified stock or pop charger is the way to go...of course, it may not look as nice as that $200 CAI setup.

You can do the same test and eliminate those variables by using the OBD IAT

You finally give something of substance by giving the link for local dyno shops. After cold calling a bunch of shops from the yellow pages I'd only found one up by Columbia.

Nope, it's been your opinion whereas the companies have backed theirs up with proof.

After reading this I can see the benefit of CAI in city or suburbia driving where you tend to sit at stoplights alot. It would keep the added power more consistent. The only question now is ... INJEN or AEM??

teach me, I want to learn. Most of the pictures of "cold air intakes" I have seen are just a big open filter under the hood where the air will be HOT. Makes no sense. What am I missing?

The "true" CAI extends downward (extended tube).
If you check the link I gave you though, a CAI really doesn't buy you much as far as air temp unless you sit at a stoplight for a long time or are on a dyno. They may (hasn't been proven...just a theory) even do worse than a Pop charger on a hot day whee the pavement radiates a lot of heat.

If you wanted the best setup, I'd either modify the stock one to remove the snorkel neck down restriction (may not be easy to do...never tried) or simply get a pop charger and seal it off.

So far, the only true cold air was made by Place Racing (no longer making parts for cars). To install it, you actually had to drill a hole through the inner fender into the open area in front of the LF wheel well. The main issue with them was that they came with monsterflow foam filters.....which didnt really filter that well and caused restriction at elevated RPM. Anyways, shoot me a PM and we can finish talking about this.

If the dynojet machine automatically converts the data into a runfile, when why would these "other" dyno runs be in excell?

Because savagecat says so. I bet hes the kind of guy that believes the car salesman saying that they have another buyer on the car he is looking at.....

Some places use Adobe, some use Word. If they set up their articles as word documents and don't want to scan in the image then it would explain it.
Again, not saying this is the case...just one possible answer as to why.
BTW, I am still waiting to hear back from Nissan Performance Magazine as to the real reason (I wrote them yesterday).

holy cow, I cannot believe I just read all of this again. ATTN:4th genners, you no longer have a monopoly on stupidity on the .org, savagecat has taken a large percentage of it to the 6th gen forum. btw savagecat, you gene pool could use a bit of chlorine.

He has an opinion, others have theirs. Can't we keep it civil and on topic?
Calling someone stupid won't get us the answer.

You can take screenshots of the runviewer and put them into ANY type of document....

Id love to
them for publishing that BS
How about this. What if they have the runfile and instead of just making it a screen shot and putting into the article, they have to plot out each point twice and take 4x the time. Somehow that doesn't make too much sense
