This is a one time only run of our CPLT Airbox add-on to our Elantra N-Line Carbon intake system.

***Please note, this airbox only fits the SXTH Element Elantra N-Line Intake system***

Air enters the SXTH Carbon snorkel and goes to our high flow / dry flow filter with integrated velocity stack that feeds the air through a 3.5in carbon fiber tube to the turbo. Due to OEM ECU limitations in place (much like current Kia Forte / Veloster Turbo) power gains are limited to 4-6whp across the rev range. With this intake, the OEM bypass valve hose is still used and the EVAP hose connections also remain for a 100% OEM installation.

Closed Box

Designed to suck air from the OEM air feed, fresh air is fed to the filter while looking great in the process. The box is made from stainless steel and powdercoated for ultimate heat protection.

Carbon Snorkel

Our carbon snorkel is constructed from 3K twill 100% carbon fiber and finished with a gloss sealer. We chose carbon for the ultimate combination of strength and heat resistance.

C.A.D. Engineered

Our CPLT Airbox is designed inside a 3D environment using 3D scans of the engine bay. This allows us to design quickly and easily in a real world setting and attain a perfect OEM fit the first time.
