    Reviews

    Street Performance High-Flow 58mm EFI Throttle Body is rated 5.0 out of 5 by 1.
    Rated 5 out of 5 by from Necessary building block for greater HP gains The SE 58mm EFI throttle body is in my opinion one of the basic building blocks in getting started on your quest for more HP. This product is an easy bolt on part with the addition of a 58mm backing plate for your air cleaner. Couple this with a high flow air filter and you have removed the first bottleneck in moving air through your engine. I would definitely invest in this part again.

    Q & A

    Compatibility w/2015 Limited and 110 Stage lll Bolt-On with 585 cams

    I have a 2015 Ultra Limited with the Stage lll 110 Bolt-On kit and 585 cams (92500035). I would like to know if the CNC ported heads and this throttle body are compatible with the currently installed kit. Thanks10Bom
    Asked by: 10Bom

    Will my stock air filter assembly on my 2017 Softail Slim S work or will I need to up grade to a different air cleaner.

    Are there any other parts required, other than remaping the EFI.

    What is the stock throttle body size of a 2016 Fat Boy S?

    Hi Char42, The stock throttle body of an American 2016 FLSTFBS is 50mm. Thank you for your question.

    110 bolt on kit application Part Number 92500035

    I do not see Part Number 92500035 listed as a compatible 110 bolt on kit. could you elaborate on this, as I was thinking of moving to this 58mm now that my 110 bolt on kit is seasoned with 15,000 miles. Big R
    Asked by: BigRmilwaukeetransplant
    Big R, The 58mm TB is compatible with your new 110 upgrade. The question you have to answer is what will you do engine wise with the increased flow to the combustion chamber. The 110 unmodified is a relatively low compression engine and will not improve in performance without either porting and decking your OEM heads or looking at the MVA heads and high compression pistons. I've gone through this process with a 2015 CVO by starting first with the 58mm TB and highflow injectors. Results on the Dyno, zip. Cut the heads, .030 head gasket, and put the 117 kit in with its own compression increase. Current numbers with the SE585 cams 120 ho, 130 tq. Pulls in every gear with no runout. Good luck with you build.

    Will the 58mm TB work on my '10 street glide that has a 96 built up to a 103 stage 3? and will it help its performance?

    My '10 Street Glide has had the motor modified from the 96 to the 103. Im not positive if it is a true Stage 3 kit or if it was pieced together by Saddle Back Harley, but the Dyno map is identical to the stage 3 dyne map in the SE catalog, hence the assumption. My other consideration is the 120ST motor. Any suggestions?
