The ECS Tuning Rear Diffuser Add-On Kit easily installs over the factory rear valance on your 2018+ Volkswagen GTI to provide the appearance of an aggressive diffuser, without the need to remove your OEM valance. Engineered in-house, our rear diffuser overlay will be sure to catch attention and turn heads! Featuring more aggressive outer blades and three new center blades to fill the massive void in the factory valance. Installs easily with our sleek mounting brackets and included hardware. 

 

PART DESIGN

• Designed in-house using state of the art 3D laser scanning and CAD technology for precision fitment 

• Overlays the factory valance to provide aggressive rear diffuser styling 

• Outer blades are designed around the OE blade surfaces and made more aggressive by lengthening and tapering the blade towards the bottom

• Center blades fill the empty cavity of the OE valance and feature countered upper mating surfaces to the OE valance for a seamless fit

• The bottom of the valance has provisions for mounting to the OE body brackets

• Sheet metal brackets are used to mount to the bottom of the OE diffuser using stainless steel hardware and rubber insulated well nuts

• Textured matte black finish resembles the OE valance texture for OE+ appearance 

• Manufactured from ABS vacuum formed plastic with UV additives to stand up to the abuse from the elements
