While reading the latest issue of 5.0 Magazine (yes, I know I own a 4.6) there's an ad in the back for JLT Performance http://www.jlttruecoldair.com/

They claim 25-35rwhp from their cold air intake. Sounds good IF it's true. Has anyone actually used a JLT intake on here or any other forums?

 

seems a little high

 

I would call bs on that one. the biggest gain is probably a densecharger or now tuneableinduction. and its probably not even half that.

 

I would call BS on that also. MAYBE in conjuction with an entire air/exhaust overhall which would include (as a minimum) CAI, headers, mid-pipe and cat-back.

You can jam all the air you want into the front, it still has to get out. Conversly, you can make the exhaust as 'free' as you want, there is only so much air being taken in to begin with. The entire system ought to be redone for maximum gains, which is certainly what they are claiming.

 

You will not gain THAT much from a JLT, but it is probally one of the best CAI's on the market right now. His design dramatically reduces IAT Temps by about 20* and improves airflow like you would not believe.

The vehicle will need to have a tune on it (for 03 cobra's at least, not sure on standard 4.6) because the car runs lean with this kit on it.

We are a distributor for JLT, so let me know

 

E-mailed JLT.......No tune needed

 

KB blower kits also say you can use the stock fuel pump too.

Don't trust everything someone sells you.

 

I have not personally seen one on a N/A Application, and based on how the electronics and computer work a tune is probally not needed...on a blower car you WILL need a retune.

 

I dont believe that much h/p, not even on a cobra

 

They get so much hp from them by installing them and running them on the dyno before the computer has a chance to relearn, there for they run very lean at first (some even stall).
