The GKTECH air diversion panels sit between your front bumper and the radiator support and not only make your engine bay look cleaner they also serve a purpose. The air diversion panels help to direct air into the radiator as opposed to around it and you will see a drop in water temperatures on the track (nothing to write home about but it all adds up) - CNC laser cut 0.07" (2mm) aluminium plate - Anodized black for that stealth look Vehicle Compatibility: - - Nissan S14 (Kouki) 240sx NOTE: Designed for the JDM grill however if you have a USDM grill it can still be used but you will need to trim the air diversion panel around 3/4" along the front
