        Better throttle response but at 3rd going into fourth gear it acts funny.

        Don’t buy!

        After speaking with the guy she at Lund Racing I found out this particular throttle body is no good. Causes jerking, stalling and vehicle shut-off. I returned for a refund. Researching online I found the same complaints and issues with this throttle body. I ended up keeping OEM.

        Throttle body review

        This item isn’t what you are looking for to add tremendous amount of horsepower but you definitely can feel a quicker acceleration with this mod. Easy install that took about a hour or less to complete and very straight forward but if you can save your money I would say do so.

        4 2019 GT - Hoop Installation Time: Less than 1 Hour

        Most Good to go

        The installation went pretty much as advertised. I did have a struggle connection the inlet tube to the TB afterward. It is positioned a little differently than the stock unit. I have the Roush cold Air Kit. I had to do some serious wiggling to get it reconnected. Once on I followed the instruction to the letter the car as advertised idles properly with and without the AC running. Only issue is under cold start conditions the engine races even higher than normal. That is annoying to my neighbors early in the morning. Aside from that I like how the car performs. I did not modify my tune for the larger TB.

        Perfect fit

        Fits perfect install took maybe 30 min car idles normal from start had no problems with that just follow there ecu relearning procedures and should run perfect only thing I had to get extra was a different coupler from JLT I have the 120mm cold air and had to get a different adapter that will fit from the 90mm throttle body to the intake but install went super smooth and easy

      Hello American Muscle, I'm planning to get this 90mm Throttle Body but just want to make sure first that it will fit properly with my 18-19 Roush Intake. I know it might be little hard to get it in but is it possible ? Thanks !!

      • The Roush intake should work with this throttle body. More than likely the coupler will need to be stretched to fit.
