      • Spiral Bore Design
      • 1" Thick - Increases Plenum Volume
      • Two Pre-drilled 1/8" NPT Ports for Methanol or Nitrous Injection

      More Power. Improve the low to mid-range torque of your Mustang's turbocharged 2.3L engine by installing a C&L Performance Throttle Body Spacer. This Throttle Body Spacer increases plenum volume by 1" to help unleash the hidden power your EcoBoost Mustang has to offer.

      Improves Fuel Economy. The C&L Performance Throttle Body Spacer not only improves the performance of your EcoBoost 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.

      Two Pre-Drilled Ports. This C&L Throttle Spacer features two pre-drilled 1/8" NPT ports to accommodate the installation of a nitrous system, methanol injection or a boost gauge. Stainless pipe plugs are also included for unused ports.

      No Tune Required. No tune is required when installed with the factory intake system alone. However if installed in conjunction with a methanol or nitrous set up a custom tune will be required for proper operation.

      Billet Aluminum Construction. CNC machined from 1" 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 2015-2020 EcoBoost Mustangs equipped with the turbocharged 2.3L in-line 4-cylinder engine and the factory throttle body installed.

        1 2015 EcoBoost - JustinV

        Machined Wildly

        This spacer looked pristine until I took it out of the box. The inside machining work makes this product a 1 out of 5. The grooves are crooked, and so is the entire circle. Super careless mistakes and bad quality control checks at the end before packing. Will be sending back.

        Works like a charm

        Bought this to install methanol injection and it works like a charm. Absolutely would recommend this to any ecoboost owners looking for a little spunk from nitrous or methanol.

        C L Throttle Body Spacer

        Looks amazing under the hood of my car, very good quality. I haven't ran it yet or even started my car at this point because I just got it today, and literally just put it on. It was super easy to install and probably only took me 10 minutes to install.

        More flow will make you go!!!

        Absolutely love my new edition to my S550!!! And that’s a huge compliment being that within the last month alone I’ve added a intercooler, charge pipes, tuner and wastegate haha! Can’t wait to throw this bad boy on along with my new CandL intake manifold spacer!!

        Easy install, not much for gains but is useful if going with nitrous or meth

        The Swirl!

        The best 1st mod for the engine compartment and the final piece you'll ever need for your last mod which is the nitrous. You can feel the air swirling fast and loosen up the engine. It's one great piece.

      Is a tune required, if you're using a aftermarket cold air intake?

      • You should have a tune with the after market cold air intake. But you do not need a tune with just the spacer.
