Wanna try an NA or JDM long runner manifold? You need these to clear the AVCS. Made from 6061 billet aluminum and left raw to look pretty as possible. Both sides have o-ring grooves so you never have to worry about leaks or using silly gaskets. Don't forget about our 2.5i/JDM Fuel Rail Adpater either!! Click Here. These also work great in reverse manifold setups.
