    More Power. A C&L Performance Throttle Body Spacer will allow you to unleash all the power your Coyote Mustang has to offer.

The Spiral Bore spins the incoming air to improve the atomization of the air fuel mixture for better combustion.

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.

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

        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.

        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.

            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!

            C L Throttle Body Spacer (11-17 GT)

            I would have given this 5 stars but it is not a complete kit. They do not include a gasket with the CandL Throttle Body Spacer (11-17 GT). They tell you to use RTV. RTV can damage your engine and void the warranty. I had to make one out of a thin sheet of gasket material. CandL Throttle Body Spacer (11-17 GT) does give a slite quicker throttle response and I feel this across the rev. range. There is a slite gain from idle to 2000 rpm. Others talk about a wistle but I have not heard one and I have taken my daughter along because she has better hearing than I do. She didn't hear a whistle or any offensive noises. I wouldn't say it is a must have but at the price why not. There are better choices. I should have returned ir and got one that includes a gasket, The gasket isnt that hard to make. Cost= 1 sheet of thin gasket material. A sharp raiser knife. Took me about 15 minutes to make.

            Quick and Easy

            Took me about 10 minutes to fully install this Spacer. I have a JLT CAI and have no issue with the CAI fitting. This Throttle Body Spacer makes a whistle whenever you accelerate, best way to explain is it enhances the noise your CAI already makes. I have Flowmaster Outlaw axlebacks and I can hear the whistle clearly over the exhaust tone. I noticed a slight change in my exhaust tone as well but only because it is my daily driver. Not a crazy gain in power or gas mileage but sounds pretty cool.

            5 2015 GT - Larry Installation Time: Afternoon

            C L throttle spacer and cold air intake

            Completed job in 3 hours. Took it easy to be sure all removed and installed equipment fit and looked good. Very pleased! Surprised how much low end power it gave me. Thought it wouldn't be that much but it shocked me. I can tell the acceleration is much quicker. Man, when I got into it "Lil Red" jumped like a missile, spun the tires easily in first gear then wiggled again going to second. Larry G. , MS.

            Save your money

            Bought this on sale in hopes of better throttle response without spending $400 for a BBK one. While yes throttle response is improved the noise it makes is awful and the instructions or lack there of is just bad. I installed it drove around the block and took it off immediately. Save your money and pass on this spacer.
