      More Power. A C&L Performance Throttle Body Spacer will allow you to unleash all the power your Coyote Mustang has to offer. The C&L Performance Throttle Body Spacer increases plenum volume by 0.75" to improve the low to mid-range torque out of your Mustang's stock 5.0L engine, with noticeable gains seen between 800 to 2500 RPM.

      Improves Fuel Economy. The C&L Performance Throttle Body Spacer not only improves the performance of your Coyote Powered Mustang, but with its unique Spiral Bore design, it also increases fuel efficiency. The Spiral Bore spins the incoming air to improve the atomization of the air fuel mixture for better combustion.

      Billet Aluminum Construction. CNC machined from 0.75" thick, high grade billet aluminum, the C&L Performance Throttle Body Spacer features a mild polished finish for an impressive under hood appearance. C&L includes all the necessary hardware and easy to understand instructions for a simple, straightforward installation.

      Application. This C&L Performance Throttle Body Spacer is specifically designed to fit the 2011-2020 GT Mustangs equipped with the 4 valve 5.0L V8 Coyote engine and the factory throttle body installed. No tune is required for operation.

        It’s okay

        I combined it with a CandL Intake and it definitely sounds more aggressive and it increased torque.

        At idle sounds normal, on the throttle has a whistle and sucking sound like a turbo with a rumble in the rear.

        Good product

        Noticed a little low end response pick up and obviously the whine is pretty awesome when you give it some throttle. The kit did not come with the gasket that was supposed to be in it. Had to make my own. Kind of disappointed on that part, but overall it was a good purchase.

        Very well made part

        I added this to my 2017 mustang gt.I already had an after market Cai on the car.I data logged the car before and after the throttle body plate..there was a slite increase in the air to fuel reading on the Graf..more than anything I gain a couple miles per gallon .so to some it up..yrs there are gains in performance when you add this to your coyote.

        Closest sound to forced induction...

        Trust me, I already know the critics are like why are you buying a pointless TB spacer? There's no horsepower gains! Well duh!! I know that, but for a person who wants to stay naturally aspirated and likes the sounds of turbos and prochargers, this mod is the closest I get to it! One thing I will say, since I added my Boss Intake, low end torque was really lagging and took a minute for the car to move. When I added this, that lag disappeared in thin air, and able to take off like a rocket. And I love the whistle sound now. Makes driving so much more enjoyable! Thanks AM!

      Questions & Answers (6 answers)

      5 Top Rated Questions

      Will this restrict a larger than stock throttle body? What is the inside diameter?

      • This C&L Throttle Body Spacer is specifically designed for use on 11-18 GT Mustangs with the factory throttle body installed and will not work with an aftermarket throttle body.

      Helpful (2)

      Are the existing TB screws long enough or do I need longer screws to install this TB?

      • The existing throttle body bolts are not long enough. This kit will include four longer bolts necessary to complete installation.

      How much hp does this add? And no tune required right?

      If I purchase a sniper efi intake manifold with a 90mm throttle opening could I use this to make the factory tb work? If not what product would I need and could you reference it to me? Besides the 90mm tb.

      Will this spacer fit on an 18 gt with a JLT intake?

      • This spacer will fit as long as you do not have a larger aftermarket throttle body.
