NRT Autosports Throttle Bodies are CAD designed to provide the ultimate solution to EFI air flow control. 6061-T6 aluminum billet construction on full CNC machining systems create the largest bores possible in the factory mounting envelope without sacrificing strength or durability like a modified casting.
 
These Throttle Bodies will fit all Jeep 4.0L engines model years 1991 through 2006 with 2 wire IAC and 1 Wire IAC. The TBs are fully compatable with the stock ecms
 
The NRT Autosports two piece construction provides the largest inlet for each throttle body while still maintaining a tapered approach to the throttle blade, flowing more air than a straight bore.  The 17-4 precipitation hardened stainless steel profiled throttle shaft used in these throttle bodies is tough enough to withstand all forms of on and off-road racing. Due to the strength of the stainless steel the shaft can be halved and profiled to present minimal resistance to flow at WOT, out flowing the competition's full round profile shaft. The NRT Autosports Throttle Body also uses only high strength sealed ball bearings with high temperature grease to assure a lifetime of operation under all conditions.  The dual wound stainless steel springs assure long service and excellent throttle control through the careful selection of spring rate for each application. The throttle blade is made from thin but tough .05" thick 5052 aluminum, elliptically profiled for quick response and clean shut-off.  The 0.100" thick laser cut steel linkage is designed to handle any driving condition and style and replicates all of the factory cable mounting positions. All NRT Autosports throttle bodies are designed with pressurization and nitrous use in mind, using materials and tolerances compatible with modern power-adders! 
 
These throttle bodies come as complete kits, allowing fast installation without modifying the factory cables, controls or brackets.
