09-14 Acura TSX Under Tray

The OEM plastic splash shield offers no protection from the elements or road debris and essentially is a gaping hole below the engine.  Many newer cars has a plastic panel that covers this whole area which at least offers water and dirt protection.  The 09-14 Acura TSX (CU2) has almost nothing to help protect you under the car.  The TBW under tray has been developed to remedy and fix this problem.  This will affix to the front bumper, and will go back behind the engine so you have a barrier between the road and the oil pan. Designed to take handle typical street use, however if you decide you want to go for a rally version offering added thickness for more regular abuse, let us know and we can customize something for you.

A door for quick oil changes has been built into this - this is designed to allow you to change the oil without having to remove the under tray.  2 simple bolts and you can drain the oil and change the filter.

Installation is relatively simple but does require a rivet nut tool for installation because Honda/Acura didn't thread the holes into the chassis. We will provide the hardware, including rivet nuts, extruded u-nuts bolts and spacers, but you will need to source your own rivet nut tool to install this.

    Excellent Product & Experience

    Posted by Alex on Jul 29th 2025

    Item shipped almost immediately & arrived faster than expected. Overall quality is great & packaging was ok (foam corners would be even better). I got the 50% stronger version & glad I did because it feels sturdy without being too heavy. Personally I got it for the aero benefits so I didn't want the plate flexing at high speeds. Which it did make the car feel a bit more planted on the highway with the bonus of also protecting the underside (not really a concern though, this car is over 15 years old and lowered for most of its life). Installation took about 30-45 minutes. All bolts were 10mm which was great. Overall great product. I was planning on making my own smooth undertray but the cost of the aluminum alone was more than expected & this was already pre-designed so it saved quite a bit of time & effort for what I wanted.
