This is 52mm ported throttle body. We remove the 48mm hour glass shape inside and taper it up to 55mm. Thin out the shaft and install new blades and ss screws. The idle screw plug has also been removed for easer tuning. All cnc machined and ready to bolt on using factory hardware and sensors. $40 will be refunded to you as soon as I receive your old one minus the sensors and brackets. Please let me know what year and model you have because there's some different linkage types. I would suggest you get a throttle body from a junkyard and send me that one. Please feel free to contact me if you have any questions. You can see in the picture the huge difference between the two. This will require you to reset your computer and clean or replace the IAC valve in order for it to re learn the idle speed.
Please note... ONLY CORES FROM A mid 96 AND UP CAN BE MADE INTO A 52mm... If you have something older you may have to find one in a junkyard to send in for core...You also have the option of sending yours in a head of time and avoiding the core charge completely. Please let me know if that is what you want to do. Also, the cores must be somewhat clean! Cores that are returned greasy or have lots of oxidation will only be refunded $15. If there is a broken screw only $10 will be refunded. Cores that are broken in any way will not be refunded at all. Having good clean cores is the only way to keep the price down... Most self help junkyards charge $30 for a used one. If you have multiple cores I can cut the price a bit too....
