So what you are saying is the screen is a filter stop?
Wouldn't it be easier to put a filter stop on the tube itself so any filter can be used on your tube.
Not everyone is running this new filter on your cai.(or might not like that filter)
Thanks,Here, this should clear up the filter install issue for you.
Torque tables in your case.
As for the JLT 127MM, I've addressed /documented this a number of times. But, for those new to the party......
I had one of the very first ones. Tune was dead nuts perfect on the dyno. But, drive it and it went nuts. Surging, bucking, all the issues you read about.
Fortunately, I had a wb air-fuel gauge. It was clear that the sensor was having a field day, adding and deleting fuel, causing massive swings-thus the surging.
My hood has a fresh air "dump" right over the filter. I'd used it with the regular JLT 110MM with no problems.
I assumed (correctly) that the airflow was being rammed too hard/quickly and this must be the culprit. I cut down the edges of the plastic housing to keep it from sealing. Still had the issue, but had to head home. About an hour into the drive the surging got so bad that it failsafed.
In true McGyver fashion I took the back panel of a granola bar box and completely taped my fresh air dump closed.
Viola. Done. Perfect.
As stated above, its turbulence. Jay has recently improved the mouth of the filter by adding a screen to disperse the airflow. Its better, but it doesn't fix it.
He's continuing to fine tune the CAI.
You can mask some of this in the tune, but not all.
Block off the oval fresh air hole that comes from your grille on a 10-13 MY car. Problem solved.
Remove the block if you go to the track. It won't matter because it doesn't occur at WOT.
I have a piece of rubber velcro'd over my fresh air inlet for daily driving. You'll still get plenty of intake air. Don't worry.
I remove it for track use.
The JLT 127MM is a fine piece and performs great, but just like a really large throttle body, it may take a little experimentation.
Block the hole and see what happens.

PLEASE REACH ME VIA EMAIL AT [email protected] AS OPPOSED TO PM. THANKS.
My surging problem is fixed, it's not the tune, you have to install the CAI correctly
Filter needs to be pulled all the way to the end of the tube, until the filter can't be pulled anymore then tighten clamp
Update
Just wanted to give a update to this post. I received the heat shield for the 13-14 and a new style dry filter and installed them. Problems solved car drives like it did when it was stock.:banana::banana:
I also want to give a thank you to JLT for taking the time to listen to their customers and give them what they want and deliver a world class product and the service to back to up.
