abunda_amazon_reviews Easy 30 minute install, Fired it up and Instantly noticed a difference. From idle through to 3500rpm This definitely makes a difference. This is installed on a 2000 Jeep Cherokee XJ Sport 4.0L. I coupled the Install with an aFe Stage 2 Air Intake system . Will be following up in a couple months to see how the mileage is affected. This was a perfect under the hood upgrade. UPDATE ..... The performance has been awesome. When off road and climbing it nice not to have to push harder it makes crawling and climbing much easier on the throttle. Fuel mileage seems to have remained constant at 21 highway and around 17 city and off-road well.... depends on what your doing. I have let a few people drive my XJ and the first thing that say is what did I do because its so crisp and responsive. Even My Repair Shop Mechanic is interest in getting one now for his Jeep! Update 8/22/2017 .... The Performance is still there And A lot had changed on my Xj including Rehearing to 4.10 with lockers, 33's $.5 Inch Lift. Average mileage has been around 16.5.

The fit and finish of the BBK is fantastic; zero complaints or issues. The straight 62mm bore is a drastic improvement over the stock tapered 55mm TB (~27% increase in cross-sectional area). The one issue I ran into was the throttle shaft tang that mates with the throttle position sensor (TPS) being about 1mm too long, causing a gap between the TPS and mating surface of the TB. This was easily remedied by gently grinding the tang down the appropriate length to close the gap. (I used a Dremel with an abrasive bit; a file, a sander, or any variety of grinding mechanisms would do the trick as well.) I only have 10 miles on it so far, but the most noticeable detail already is the additional throttle response from idle and the addition of some smooth low-end power. I haven't noticed any increased whistling or intake noise, and my ECU - though initially perturbed - quickly compensated for the new dynamics at idle speed. To note, in my particular intake setup, the supplied throttle plate adjustment screw was too long. Therefore I've omitted the screw for now, implying that the throttle plate is fully closed at idle and my idle air control valve (IAC) is fully in charge of idle speed.
