COBB Sound Symposer Delete Kit for all 2013, 2014, 2015, 2016, 2017 and 2018 Focus STs.

Give your 2013-2018 Focus ST a nice, clean look under the hood with this all-new sound symposer delete kit from COBB!

Ford designed the 2013-2018 Focus ST with a sound symposer system that generates false engine noise which is carried into the cabin. Many agree this is a bit much, especially after you have upgraded your intake to an aftermarket one like the COBB cold air intake system. To remedy this, the masterminds over at COBB came up with this beautifully engineered delete kit that includes a physical block-off plate to allow the complete or partial removal of the symposer system from your Focus ST.

Features and Benefits:
- Durable 6061 Aluminum Block-Off Plate
- Stylish Black Anodized Finish
- Custom Laser Etched COBB Logo
- Easily Reversible Back to Stock
- Uses Factory Mounting Hardware

Kit Includes:
- Sound Symposer Delete Plate
- 1/8" NPT Plug
- 1/8" NPT 90 Degree Elbow
- COBB Stickers
- Zip Tie
- Allen Key

*The COBB Sound Symposer Delete Kit is NOT compatible with the 2016-2018 Focus RS.

COBB provides two options with every sound symposer delete kit, a plug and a boost port. If your Focus ST's setup could make good use of an accurate boost source off of the intake manifold, install the 90 degree brass elbow and connect it your gauge or other necessary hardware. If you don’t require a boost source, simply install the plug that came with your kit using the supplied Allen key.

With tuners, shifters, exhausts and more, you can give your EcoBoost powered Focus ST a big boost with some help from COBB and CJ Pony Parts. Order a COBB Sound Symposer Delete Kit for your 2013, 2014, 2015, 2016, 2017 or 2018 Focus ST from CJ Pony Parts today!

We’re here with a Cobb sound symposer delete fitting your 2013 through 2016 Focus ST. The sound symposer tube goes from the front of the engine into your interior, and basically funnels a fake intake sound into your car. Once you add an aftermarket air intake it basically does nothing but clog up your engine bay. This will allow you to delete it using the 6061 aluminum plate. Cobb also provides two fittings. One [inaudible 00:00:32] fitting for stock use, or this 90 degree elbow if you're running an aftermarket relocated blow off valve.
