Replace your restrictive stock throttle body with this 1986-1993 Mustang Accufab 90mm throttle body! Accufab's throttle body features a 90mm throttle opening, as well as a new and improved full body stainless steel shaft. The linkage arm is a 3-position system with an anodized black threaded ball stud to make sure your throttle blade is in the correct position at all times. Accufab includes an O-ring to ensure a leak resistant seal up to 100 psi. An idle air control provision is now in place to ensure a factory idle is achieved.

Accufab manufactures this throttle body in the USA for the ultimate peace of mind!

    Lmr. Thank you for fast shipping and update is order processed. My first order from you all and it was a good one.

    Now for the ACCUFLOPS F90. Recieved my order and opened it.I Outside appearance was great. Inside the throttle blade, thou not seen was poorly processed at there machine shop. I even reached out to accufab's George Klass who did respond. Function wise it will do its job. But when the ACCUFAB was stamped into the blade someone was clearly not indexing the blade correctly at the process. Call me anal or over OCD but when dropping my money on a unit I expect it to arrive without flaw. After being told by MR. Klass I could ship it back to fix it is just not feasible. Incurred expense on a QA issue that should never left there facility. Upon the disatifaction that they would not take responsibility and hanging up at my request for a new throttle blade I hung up. Recieve an immediate voicemail back that it would then be free. Sorry but a throttle blade that was correct should have been the first answer since I provided photo evidence. Thumbs down on there qualily management. A simple blade would been much appreciated. Though I wont see this with intake plumbing its a bother.
    From LMR.com: Hey Shane, I'm glad that we were able to speak on this matter! -Trey
