What is your guys thoughts on an air intake for the 4.0? Is it worth it or is it a waste of money?
True on the Wrangler TJ. It can help on some cars though, some air intakes have purposely added restrictions for reasons that include making it quieter to (surprisingly) reducing power. The Corvette brass at GM forced the Camaro people to reduce the power of the Z-28 because it was found to be faster than the standard Corvette... they did do by restricting its air intake. The Mustang 5.0L also has a restrictive air intake. Replacing their intakes with a performance/non-restrictive air intake can really boost their power.The myth of an air intake has to be one of the Internets oldest ones.

The TJ, however, does not have a restrictive air intake so its performance won't be enhanced by swapping on an aftermarket air intake.
I really want a new intake, simply for a little more throaty sound.
The one I want was like $300.
So no. Heh.
Ha yep I'm an old guy and I know what you mean on that Quadrajet carburetor, it could really make some noise with its air cleaner off. I was a kid in '64-65 driving my dad's '62 Olds Starfire with a 394 and Quadrajet and used to take the air cleaner off when we'd go cruising, it sounded pretty awesome to us high school kids for sure. I was sure shocked how badly it got beat by a buddy's 327 Chevy Nova in a street race behind the school. I was was even more shocked to hear him chirp his tires shifting into 3rd gear about a hundred yards in front of me on the street as his Nova blew my doors off lol. Those were the days... big V8s that rumbled!Ok for the old guys..... back in the day 60s and 70s, we would turn the top of the air cleaner over on our small block chevy powered pickups. Did it help with power? Who knows, we did it because it sounded pretty cool when you opened up that quadrajet carb.
