Based on what your signals were reading that'd effect only shifts? Or would it effect horsepower as well? Also, because of those testing are you running your stock cai?
If you know how to fit the stock airbox to the CJ intake manifold I am all ears. As is, I am using a custom Airaid setup where I modified a 2010 GT Airaid intake tube to mate to the GT500 TB and Airaid airbox.



kdanner posted some of the technical finding from the testing: http://www.dfw50s.com/showpost.php?p...&postcount=404

Keep an eye on those JLT fittings. Eventually they will break if they are not the metal pieces.

We did back to back testing at the track between the stock airbox and the JLT. Both using the same tune minus the changes for the MAF transfer function. There was a .06 difference between the two. That falls within the margin of error. In a nutshell, buy an aftermarket CAI for looks/sound.

The video about IAT's prove nothing. What he doesn't discuss is that when using the stock intake, the IAT's sitting still in traffic will not increase nearly as fast vs. using an aftermarket CAI. We all live in Texas and know how hot it gets here. A DD car will fare much better with the stock intake.

Regarding dyno numbers, dyno'ing with the hood open will show an open air filter producing gains over stock but that is a false positive. The minute the hood closes those gains disappear. We drive our cars with the hood closed, not open.

I do like the stock box, especially the fact it's a closed element design to help negate any effect from under hood temps on the IATs. I just don't like the accordion style couples and tube they use on it because I would imagine the interference in airflow that would cause. Why not just make a straight flow through tube from the factory and be done?...
It is one without the filter stop. The unit I have we tested with is what led the brand "j" owner to put a filter stop on his product.
