BBK 1724 62mm Throttle Body - High Flow Power Plus Series for Jeep 4.0L

2003 wrangler 215000 miles Daily driver 5 speed 33s 4:10s I replaced the factory throttle body after bad idle issues and ruled out the idle air control and throttle position sensor. Oringinal throttle body had tons of excessive play in the butterfly causing it to stick. Easy to install, reset the computer to zero out. I didnt expect any change in performance due to "the experts' claiming this wouldnt net any. I test drove and the performance improvment was excellent. Better power and throttle response. How much power? Enough that I down shift less up hills, driving in 40 mp headwinds have no affect anymore. Its more pleasant to commute to work in. Conclusion, I wish I wouldnt have waited until I had to buy it. Its that good. Is it a substitute for a gear swap? No. It will take a sorted out, good driving wrangler and make it noticeably better.

Arrived on time, installed in just a few minutes using existing components. The gaskets supplied seal well, and the 5mm hex bolts supplied also fit properly. When bolting this throttle body to my 1994 4.0L intake, you do notice the obvious step down from 62mm in the throttle body, to 60mm on the intake, however I did notice an immediate increase in throttle response! It seemed to smooth out the power band as well, allowing my Cherokee to pull up hill much easier. I live here in Colorado at 6200ft, so a definite improvement! Remember that your intake/head/exhaust is only as strong as it’s weakest link. So if you just put this throttle body on without opening up any other passages, you may not see an obvious improvement. Make sure to go the extra mile and install a cold air intake, and high flow exhaust to compliment this throttle body. As you have to remove the intake to replace the exhaust manifold, you might as well gasket match and port the intake to the head, as well as the inlet to the plenum to the throttle body, which can be done with a marker, new gaskets, and a Dremel with an aluminum burr. Ported the intake inlet for the TB and the runners into the head, definitely feel a difference in overall powerband still! I’ll say that my idle set screw was low enough that the throttle plate sat flush against the TB bore, enough to stick the throttle closed. A minor adjustment and new loctite solved the issue though. Definitely worth it if you’re looking to squeeze performance out of your 4.0.

I installed this on a 4.7 lieter stroker I built 2 years ago. I was running the stock throttle body because at the time was running out of money to throw at it. Finally bought the bbk this summer along with a spacer and a high flow intake every thing worked together quite well ! The only issue I Ran into was with the throttle body spacer bolts the had a regular bolt head on them and could not be used because there was no way to fit a socket on them and the bbk ones were to short because they didn't expect for a spacer so I had to go buy some longer bolts like the bbk bolts at the hardware store. THE POWER INCREASE IS EXPONENTIAL.... keep in mind I put this on a 4.7 but however if you are running a stock 4 leiter and running larger than stock tires you probably have the overdrive gear power loss problem i used to with my stock 4 leiter . My belief is this upgrade along with the spacer and intake you will experience a vast improvement best I can figure this combo probably will add at least 15 possible 25/30 hp to your motor also if you upgrade your injectors and rails you may even get more

Great product. After a little work to get the Idle Air Control motor to fit this bolted right into place and solved my vacuum leak issues that the original throttle body had as it was leaking past the butterfly valve bearings and causing a high idle issue. It is well made and looks like it should last for another 23 years like the last one. Update: I had to knock a star off this review because the throttle body developed a very high pitched squeal right when I would move the gas peddle. Not sure if it was leaking air in some strange way past the o rings or what but it was driving me crazy. I rebuilt my old throttle body with new o rings to seal the leak and that made the squeal go away. Still a well built part so i may just take it apart and rebuild this one as a spare now. Such is the way of new parts on a Jeep though.

Read all the reviews and decided to bite the bullet and order one. Fast shipping and installed less than an hour after getting it on my doorstep! No problem whatsoever with the install, I’ve read that others had to shim the TPS and but I looked at the shafts of both of the TB, where the TPS mounts, on the bench and They were the same exact size. Hardware supplied with the BBK fit perfect and also the gaskets that mates the manifold and TB. Also unplugged my battery and Reset the ECM as well. Specs: 92 Jeep 4.0 Afe cold air intake stage 2 Banks monster 2.5 exhaust system Thunderbolt highflow 2.5 cat Initial Thoughts: It’s makes an awesome sound when you whip the throttle cable Smoothness in the pedal and also responsiveness was instantly noticeable. I would recommend this to anyone.

If your buying it for a 4.0 don’t, it’s an aftermarket part and these engines don’t do well with aftermarket parts. It’s an easy install and definitely gives you a little more power but not $300.00 worth also if you don’t have a cold air intake your going to need one which is another $350.00 , it’s very finicky about TPS I had to purchase a Mopar And it finally ran decent but it would all of a sudden die when using the gas a lot like In traffic. Could be I got a defective one but I got sick of dying in traffic so I put my Mopar throttle body back on. Customer service is terrible especially the guy with Australian accent. If it ain’t broke don’t fix it save the money.

Bought it for my cherokee xj 2000 - big difference in the way it breathes and performs. Brilliant!

Great quallity, comes with all the things you need. Huge positive change in the throttle response.

Nothing to dislike. Good quality from BBK. Nil issues with install. Works well. The TB complements others engine modifications i.e. exhaust, cold air, edelbrock head, cam, roller rockers etc. Feels less restricted. All sensors fit well.
