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.
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. |
See, that's what always makes it so hard to swallow about CAIs. Could they be effective? Yes, but not everyone wants to tune their vehicle to support them. I'm sure that a CAI would become beneficial with a matching diameter throttle body, but then you don't know how much the CAI is really doing.
I love the change in exhaust note that mine gave me, and it's a little extra insurance towards my goal of getting a legit 400 rwhp out of my car.
Thanks for the insight, wbt.
