All the fastest 3.7 NA cars in the 1/4 mile run the JLT CAI. Look it up on the sticky, the top 6 NA stangs are JLT. Even though Airaid has better marketing and sold 10 times as many, the good serious racers prefer the JLT.
The airaid does moan a lot, and apparently some guys like that lol. Moan vs. Performance?

According to the video that Mustang saw significant improvement with only the addition of an Airaid CAI. The additional link to a post on this forum shows the results of a dyno run for my vehicle and the numbers were pretty close to the vehicle in the video and they were achieved with no tune on 87 grade pump gas and the installation of an Airaid CAI.

IIRC, the JLT does require a tune and perhaps the reason that JLT's are on most of the top 1/4 mile performers is that most of those owners have either made their mods post warranty expiration or have decided that performance trumps warranty coverage. At any rate, there are many other mods made to those cars than just a CAI and there is almost always a tune involved. I believe that the Airaid is a worthy alternative for someone who is interested in preserving their warranty and wants to avoid the addition of a tune which may or may not cause warranty issues depending on the dealer utilized for service.
The JLT CAI for the 3.7 V6 doesn't require a tune.
