Product details
A billet adapter that bolts an HKS blow-off valve onto the factory bypass-valve location of the 2011-2015 Kia Optima 2.0 turbo (G4KH Theta II T-GDi). No welding, no cutting.
- CNC-machined 6061-T6 billet aluminium
- The HKS valve is not included
- Direct fit, about 30 minutes to install
What it changes: the valve you run and its sound. An adapter makes no power, and the factory valve holds boost fine on a stock-turbo car; this suits owners who want the HKS sound or already own the valve. A fully vented valve can upset fuelling between shifts on some setups; a recirculating setting avoids it.
Fits: Kia Optima (TF) 2.0T turbo, 2011-2015. Not the 2.4, not confirmed for the 2016-2020 JF Optima GT; the Sonata 2.0T takes a different adapter.
