AEM Brute Force Intake and TBS for a 2.5l?

Removing the mechanical cooling fan that is attached to the waterpump, and installing an electric fan onto the radiator. The engine no longer spins the fan, causing less resistance on the motor. Flex-a-lite claims it adds 5 hp, and 12 lbs of torque, but that's probably on the 4.0L.

When you do the TB spacer, apply a liberal amount of gasket spray on to the paper gasket they give you. just a little insurance. Oh ya, make sure everything is plugged back in when you restart the motor, I forgot to plug the TB harness back in and got a error message. Luckily I had a snap on ecu reader handy and was able to erase the codes.

Twistedcopper-- I'm with you on the 2.5l, I liked mine. Slightly shaved head, cleaned up the ports a little, header, 2.5" exhaust with no cat, .75" homemade TBS, homemade intake tube and cone, Mopar roller rockers, chip, and some ignition upgrades. Even with the factory duration camshaft and all the factory injection equipment, it ran really good. I'm pretty sure that not a single soul here will believe me but......If I REALLY got on it (and the rear driveshaft stayed under the Jeep) it would haze the 36" TSLs from a stop. Like you said, the electric fan is a good mod. Anything to reduce drag on that little engine as it tries to rev up will show good results.

The down side? NO bottom end power, if I wasn't turning 3,500 rpm+ then it wasn't doing much. If you drive a 2.5l the way it needs to be driven in order to produce power.....they don't hold together, and there were/are no stronger aftermarket bottom end parts available.

But if that spacer has the ribbing design, it causes the air to (And I use this term loosely) "Swirl" Increasing the velocity of the air

the velocity of air is due to the vacuum of the piston drawing down.... i would think that a "swirl" would actually increase the drag on the incoming air... but since it gives the air a uniform constant pattern of travel... it keeps it very organized and decreases turbulence

I didn't even know you could get some of that stuff for that motor. Man I wish I still didn't, but now I do! RUh roh...
