I am trying to find out if any of you fellers have installed a CJ intake on a 2011+? Any pics or tips on tune would be very helpful. Thanks:893karatesmiley-thu

Thank you. I put about 10 hours of labor into it to get to fit properly. More than likely I will be buying the FRPP tube once they are released.

10 hours yikes! What modifications have to be done to get it to fit?

The breather fitting on the passenger side has to be blocked off.

A new hole has to be drilled in the tube for the driver side breather hose to connect to.

The end of the tube where the MAF is located has to be trimmed at varying angles to mount to the airbox assembly.

Basically a lot of measuring, cutting, blending and drilling.

Sheesh, that's a bit much. I was under the impression Ford would build this to bolt right up. Thanks for the info.

So what kind of numbers are you getting out of your setup and do you feel it was worth all of the mod time? looks pretty sick by the way!

It ran 10.92 in the heat last month at Ennis.

Off topic question but, of all the forums I've been on, I've never seen such a disputed performance mod. When I see people post increases in power and torque with things like, cams, headers, blowers, mid pipes, tires, shocks, hell even other intake manifolds on other cars, no one ever goes through this much trouble to prove it's "worth it." On each and every other forum when someone gained power with any mod, the car was faster. Why are you going through so much trouble with this one mod? Was your car not faster or more powerful with this mod? Just curious.

There is quite a history out there of people disputing it's worth (Boss intake). Due to the mis-information floating around, I wanted to clear it up and present facts to dispel the rumors.

On the CJ intake, I like to have data to coincide with results. Without data, it's all heresy. Hopefully it will help those who are interested in making the switch and what it takes to be successful with it.

I didn't want to resurrect that thread to be honest. Just too much emotion lol. You are clearly one of the more level-headed posters here so wanted to ask you directly without getting a ton of drama and biased posts degenerating the information.

It's just really confusing why there is so much debate on this one part on this forum. Even when I ventured corvetteforum or supraforums much more, it was never an argument about power/performance gains. If someones car became more powerful, it went faster. Point blank. There was no debating. If someone posted a dyno sheet of a cam install showing a 40hp increase to the wheels, no one ever said, "Well we really need to go to the track to see if it's worth it."

I think the deal with the Boss intake compared to stock is far too many are pansies that won't bang the gears at 7800 and let the clutch fly on the starting line with the car on the limiter. If you don't drive it that way, it doesn't work very well compared to the stocker. Also needs some driveline upgrades to keep from breaking things and to make that sort of driving actually possible. With an automatic it's simpler, but due to the even larger RPM drop on the gear changes, the shifts become still more critical. If you let it fall into the basement, you're done.

Don't get me wrong, I think the dyno is a great tool to determine where your powerband is for example. You can look at power curves to determine shift points, etc. With certain parts/applications on these cars the numbers don't always translate to better track times.

Thank you and well said. So I understand what you mean then regarding the Boss intake on the standard 5.0 GT. What about the Cobra Jet? In the dyno from the other forum, it did show an increase in power and torque consistently greater than the Boss IM over the entire graph. So why wouldn't a car equipped the CJIM be faster than an equally modded car using the Boss IM?
